Star Trek VI: The Undiscovered Country

Corrected entry: During the mashed potatoes scene, Lt. Valeris demonstrates that it's impossible to fire a phaser on board the Enterprise without setting off a ship-wide alarm. However later in the film, she murders the two assassins, Burke and Samnoe using, according to McCoy, "a phaser on stun at close range." Yet no alarm sounded in the ship, alerting the crew that a phaser had been fired on board.


Correction: That was the whole point he was making when he said it was set to stun. When the phasers are set to stun, they don't set off the alarm, but if fired at close enough range they're still able to cause enough trauma to kill. Checkov also explains this when another crew member asks why it wasn't just set to kill.


Corrected entry: If only two months went by between the explosion of the Klingon moon and the meeting at Starfleet Headquarters, when exactly did Chang and his cohorts have the time to construct the bird-of-prey that can fire while cloaked? Two months would not have been long enough to build such a vessel, and since there was no reason for the peace talks until after the moon exploded, there would be no reason to have such a vessel being built before the events of the movie happen.

Correction: No reason? Seriously? Up until the destruction of Praxis, the Klingon Empire has been in a state of cold war against the Federation for over twenty years - while outright conflict was banned under the Treaty of Organia, this certainly didn't prevent a number of incidents from occurring. And the Federation is only one of their neighbours who could potentially threaten them. Developing the technology to allow a ship to fire while cloaked would be of obvious interest to the Klingon High Command, so it's not remotely unreasonable that a prototype could exist that Chang could commandeer to disrupt the peace process.

Corrected entry: At the start of Kirk and McCoy's trial, the clock on the Enterprise shows the time to be 11:15:07, but when the trial is over and the crew discuss the sentence, the clock shows 10:45:17.

00:45:40 - 00:53:05


Correction: This was not a ten-minute trial and actually took several days.

JC Fernandez

Corrected entry: Valeris informs the crew that her comrades will make sure to jam ship to ship transmissions, yet minutes later the Enterprise is able to contact the Excelsior. In addition, why wouldn't the Excelsior contact Khitomer to warn them of the impending assassination attempt?

01:27:40 - 01:30:35


Correction: Valeris specifically says "ship to shore" not "ship to ship." Different communication protocols and hence one could be jammed without necessarily causing a problem with the other. And as to why Excelsior didn't contact anyone, that may or may not be an error. It would depend on how the ship to shore transmissions were being blocked. In order to block the Enterprise's communications at all without an active agent on the ship anymore would require blocking the transmission at the receiving end. In this case, they probably had communication to or from Khitomer blocked, since that is infinitely easier than blocking all communication in the whole quadrant. And if that's the case, Excelsior would be just as unable to warn Khitomer and stop the assassination as Enterprise was.

Corrected entry: Why would Valeris leave the bodies of Burke and Samno in the halls to be discovered so easily? Wouldn't it have been better to stow their bodies away to delay discovery as long as possible (at least until after the Peace Conference)?



Correction: Because it would be illogical. She had to do away with both of them at the same time (if one goes missing, the other might get suspicious and talk) and perhaps she didn't have the time to plan an arrangement where she could meet with them and arrange a hit. So her best bet was to sneak up on both of them and shoot them. It's a lot easier and faster to shoot two people and run away than it is to drag two bodies through the ship's corridors and risk discovery.

Corrected entry: After the cloaked Bird of Prey attacks the U.S.S Excelsior, Chekov turns around and informs Kirk that "Excelsior's been hit," but it is not Chekov's voice or accent saying it. The accent sounds American.


Correction: Chekov doesn't say anything. He turns to look at Kirk in shock, but if you look at his mouth, his lips don't move. It's someone else entirely announcing that the Excelsior has been hit.

Garlonuss Premium member

Corrected entry: After Spock and McCoy rig the photon torpedo to lock on to plasma discharge, why did the torpedo only detect Chang's vessel and not the Excelsior's?



Correction: They 'doctored' the torpedo specifically to track the exhaust trail generated by a Klingon Bird of Prey's warp drive signature.

Quantom X Premium member

Corrected entry: When Lt. Valeris is exposed as a conspirator, she states to Kirk: "'Let them die' you said. Did I misinterpret you?" However she could not have known this, because when he said it he was alone with Spock (after the original mission briefing at Starfleet Headquarters).

00:11:05 - 01:23:45

Correction: Plenty of time after he said that for Spock to pass along that information to Valeris; it would have been logical for him to advise her of Kirk's feelings since they had a direct impact on the mission. Even if Spock didn't tell Valeris you must remember that she was part of a huge conspiracy to keep the war going between humans and Klingons. It would have made sense for someone to be listening in on the conversation in the briefing room. In fact, during the scene where Kirk says that, there is a shadow in the back of the room that many believe to be Valeris listening in. This is best seen in the widescreen version.

BocaDavie Premium member

Corrected entry: Why is Chekov, who is Chief of Security aboard the Enterprise-A, unaware that firing a phaser aboard ship sets off an alarm?


Correction: Because, as can be seen throughout this movie (crewmen beaming off the ship to assassinate the Klingon ambassador, then tampering with files to make it look like the Enterprise fired the torpedoes) he's not a very good security officer.

JC Fernandez

Corrected entry: Towards the end of the film, the Enterprise is getting an audio/visual transmission from Captain Sulu on the Excelsior. You see Captain Sulu on a big screen. Female Vulcan, Lt. Valeris, is standing right in front of the screen. You can see a ledge at the bottom of the screen, and her shoulders are even with the ledge, and she's near the middle of the screen. Then they switch to a shot of Captain Kirk, and then back to a closer shot of the screen. This time, Lt. Valeris has disappeared. You can see the bottom ledge and the middle of the screen. Then there's another shot of Kirk, then back to the screen, with Lt. Valeris magically back again.

Correction: The shots of the screen without Valeris in front are shot from her position (but not her view) to give the audience an uninterrupted view of the screen. It's obvious we are closer to the viewscreen for those shots. In all the further shots, Valeris is in place where she should be.


Corrected entry: In the scene where Lt. Valeris finds the gravity boots, at the end of the scene she attaches them to the locker door. Just before she places the boots on the door, you can see velcro or some other kind sticky material on the locker door.

Correction: There are scratches on the door, not velcro or glue.


Corrected entry: When Valeris slides down the pole, the corridor wall shakes when she bumps it.

Correction: There is no reason a flexible panel can't be used to conceal a compartment of some kind, nor to assume the panel must be a totally rigid support structure.


Corrected entry: After the first conference with the president of the Federation, all the men file out of the room, save Ambassador Sarek, who can be seen sitting in a chair beside the president's desk. In this shot, the president reaches for his eyeglasses. The very next shot cuts to the president taking off the glasses, showing the side of his desk where Sarek was sitting - but Sarek isn't there, and nor is his armchair.

Correction: Carefully comparing the two shots, the second angle has moved to the opposite side of the desk so that Sarek (and his chair) are just off camera.


Corrected entry: The character of Valeris was originally slated to be Lt. Saavik. The filmmakers tried to get Kirstie Alley back, but found out that her stardom in "Cheers" now made her too expensive. It was then decided that Saavik as she was known would never betray the Federation, so Valeris was created. This explains Valeris' infatuation with whether Spock is lying, as her words were originally Saavik's, mirrored in "The Wrath of Khan" (when Spock tells her, "I exaggerated," after she accuses him, "You lied.").

Correction: First, Saavik was already recast with Robin Curtis for Star Trek III and IV, so Alley was barely an issue for this film. Second, the exchange you mention is not a reference to the earlier film, but to the long-standing stipulation that Vulcans, as a rule, do not lie, established early in the original 1960s TV series.


Corrected entry: In the prison, Kirk is being accosted by the huge alien that wants Kirk's clothes. The alien shouts angrily at him, yet the voice you hear doesn't match the alien's lip movements. In fact, most of the time the alien's lips don't even move.


Correction: He's an alien and doesn't conform to human attributes (like the alien with his genitals on his knees).

JC Fernandez

Corrected entry: After Spock orders the search for the gravity boots, there is a scene of a crewman removing a wall panel. As he swings the panel past the camera, the dimensions of the panel are seen on the back in black magic marker.

wizard_of_gore Premium member

Correction: There is no reason that panels can't have their dimensions written on them in anything that looks like magic marker.

Corrected entry: In his log entry at the beginning of the movie, Captain Sulu mentions that he has been commanding the Excelsior for three years on a mission in Beta Quadrant. In the next scene, as they walk into the briefing at Starfleet Command, McCoy asks where Sulu is. Kirk has to remind him that Sulu is now a captain, and on assignment. It seems odd that McCoy wouldn't have known that, or that he would have expected Sulu at a briefing taking place very far away from the location of Sulu's mission.

Correction: In any large organization not everyone knows where everyone else is at all time. Kirk's reminder may have been a way of saying that a captain is not always able to be where he would like to be. He may have orders to be elsewhere.


Corrected entry: In the scene where McCoy and Kirk are planning their escape in their bunk beds on the prison colony. It seems they are in a no win situation and McCoy mentions "Kobeyashi Maru". Kobeyashi Maru is the no win training scenario at the beginning of Star Trek 2.

Correction: Far too obvious to be trivia.

Jason Hoffman

Corrected entry: When the court is listening to the playback of Kirk's personal log stating he never could forgive the Klingons for the death of his son, General Chang is standing behind Kirk and several meters away. He asks Kirk if those were his words. Kirk says, "Those words were spoken by me." When Kirk's defense counsel objects, we see a wide angle shot of the room behind Kirk, and Chang is no longer there.

wizard_of_gore Premium member

Correction: Chang is standing by the technicians operating the audio equipment, below and to the right (from the judge's perspective) from where the judge sits. The view of this section of the courtroom is obstructed by the ledge in the shot where the defense counsel objects.

JC Fernandez

Corrected entry: In the scene where the Enterprise surrenders and Kirk and McCoy are about to beam to the Kilingon ship, if you watch carefully you can see Spock put his hand on Kirk's shoulder and place the tracking device there, which comes into play later when the Enterprise rescues him from the dilithium asteroid.

Correction: This is an important plot point, not trivia.

wizard_of_gore Premium member

Corrected entry: Enterprise hits the prototype Bird Of Prey with a torpedo they build with the equipment they're carrying for categorizing gaseous anomalies. At the beginning of the film, we hear that its actually the Excelsior that is out on a mission categorizing gaseous anomalies. Considering Enterprise was at dock and the crew decommissioned, its unlikely they would have had the equipment on board.

Correction: There are any number of reasons why the Enterprise could have had this equipment on board. Perhaps it was there for a long time, and they were waiting to transfer it to another vessel. Also, the crew was not decommissioned at the beginning of the film, considering they were sent to escort the Klingon ship through Federation space.

Corrected entry: When Praxis explodes, it's real bad luck that the Excelsior is on the same level as the two-dimensional expanding shock wave. Couldn't the crew bring the ship easily out of the way by moving it "up" or "down"?

Correction: Excelsior is not using long range sensors at the time, so they don't detect the shock wave until it's almost upon them. First, they don't have time to react and, second, the ship can only move vertically using thrusters, which are not fast enough.

wizard_of_gore Premium member

Corrected entry: When the Klingon Ship is attacked, the the colour of Klingon blood is a very bright purple. In Star Trek Generations, one of the Klingon sisters is hit in the mouth and the blood is red.

Correction: This film came first, so this is not a mistake for this film. It's a mistake for the next film that fails to maintain the continuity.


Corrected entry: When the Chancellor's ship is fired upon by the cloaked Bird of Prey, the clock above the Enterprise bridge viewer shows the time as 01:18. When the assassins have beamed back to the Enterprise and the Klingon ship begins to list, the time is 01:38. Right after this, when Chang tell Kirk that he will "Blow you out of the stars", the clock above the bridge viewer shows a time of 01:29. This is on the DVD version.

Correction: Who said it's a clock? It could be a magnification scale for the main viewer, an increment of pitch or yaw, or even 'elapsed time' from a given event point, and it has been reset to begin from another point in between the times we see it.

Corrected entry: Spock interrogates Lt. Valeris with the mind meld, he finishes and takes his hands off her. She is in some kind of emotional trauma, her mouth is wide open gasping like a fish and she's whimpering. Spock turns around and the camera angle changes to face him. In the background Valeris is standing there looking very cool and calm. I'd imagine it would be rather difficult to collect herself in less than a second.


Correction: Vulcans have the ability to block off all emotions, so it is possible for her to regain her composure very quickly.

Corrected entry: When searching the crew quarters, a magnetic boot is found in Dax's locker. The locker door either shows damage in the paint when the scene had to be re-shot or it's the device to hang a non-magnetic boot onto a non-metal door. This is evident both when Valeris hangs the boot on the door and when Chekov removes it later on.



Correction: It is someone's locker that is probably opened/closed 3 or 4 times a day. It is bound to show some wear and tear.

Soylent Purple

Corrected entry: Right before Kirk beams aboard the Klingon vessel, Spock pats him on the back. He turns around and you can see the large black tracking device that Spock has stuck to his back. Throughout the film they use this device to track Kirk. Kirk was arrested, sentenced, and sent to a prison. Kirk wears his uniform throughout this entire process and the tracking device is blatantly obvious on him. Why didn't any Of his many Klingon guards frisk him and remove it?


Correction: This is not a tracking device, it is simply a patch made of viridium. The Klingons might not have known what is was or, if they did, that the Enterprise's scanners were capable of detecting this substance across a great distance.

wizard_of_gore Premium member

Corrected entry: The character of Colonal West is an uncredited character. This character is portrayed by Rene Auberjunois, the same actor who plays Odo on DS9. Any actors appearing in a ST movie out of character are uncredited. (Neelix as the Holodeck Mate'd in ST: First Contact, and Tuvok on the bridge of the Enterprise B in Generations) However, this came out before DS9, so he must have already been signed on to the series.

Correction: Very unlikely - the film came out in 1991, and DS9 didn't premiere until two years later. It would be unheard of for an actor to commit that far ahead - it's highly likely that the character hadn't even been developed at that point, let alone cast. The real reason is that Rene's scenes were cut from the original cinematic release, hence no credit. They were restored for video and DVD releases, where he remains uncredited, possibly because he was in DS9 by that point. That being said, your basic point is incorrect - despite playing Worf in the Next Generation at the time, Michael Dorn is credited for this film (he's listed as "Klingon Defence Attorney", but is named in the film as Colonel Worf, possibly an ancestor of his usual character).

Tailkinker Premium member

Corrected entry: Captian Sulu's coffee mug clearly shows "NCC-2000 U.S.S. Excelsior" on the side of it. A few scenes later, when the mug is vibrating and bouncing around on the table, the writing is gone.

Correction: The writing remains the whole time, it's just that the side of the mug without the writing is facing the camera.

Corrected entry: When Kirk is being arrested on the Bird-of-Prey, they show him being handcuffed. Then there is a cut to a close up of Kirk saying something, then back to a wide shot of him being handcuffed again.

Correction: Not sure where you got the idea that he was being handcuffed again. Kirk's hands were in the cuffs when the wide shot was shown, and the Klingon made no gesture that he was putting them on again.

Corrected entry: At the beginning of the movie, the Excelsior is hit by a shockwave coming from the Klingon moon Praxis (the Excelsior would be in Federation space, dozens of light years from the moon). The force of the shockwave is such that the ship is physically thrown about, as are the crew. A blast that is so strong at such an extreme range would surely destroy not only the moon but also the Klingon homeworld and most other things in Klingon territory. This, however, isn't the case; Praxis is later shown to be only half destroyed.

Correction: This is actually quite easily explained. There are three components to consider, the nature of the shockwave, the direction of travel, and the relative masses of the Excelsior versus star systems and planets. The shockwave we saw, first of all, was subspace-based. This accounts for how fast and how far the shockwave travelled. The accident was caused in a dilithium mining facility, an explosion of any type surrounded by that much dilithium would necessarily cause a strong subspace reaction. Next, an explosion does not necessarily always explode in all directions evenly. When a reactor wall gives way, the explosion goes in all directions, but it does NOT DO SO EVENLY. The bulk of the force goes where it is easiest for it to do so. Were this not a fact of physics, rocket engines would not work. It is not at all inconceivable that the primary force of the explosion was outward away from the planet, and only enough force went in the other direction to shatter about half the moon, thus sparing the other half of the moon and leaving Kronos initially untouched physically (though radiation dammage and the falling debris will soon cause major trouble). Now, even with the shockwave travelling out away from Kronos, everything along the way is going to be hit. But the amount of force in the subspace shockwave shown in the movie CAN NOT POSSIBLY equal the force of the PHYSICAL shockwave. The subspace shockwave was created from translating part of the energy of the physical shockwave into subspace. Also, the original author seems to use laws of physics that apply to the physical world when guessing the power of the initial shockwave. However, subspace is a VERY energetic medium, so while some power would be lost, a subspace shockwave would last much longer (time) than a phsical shockwave, because it would lose power much slower. So while the Excelsior was tossed around like a poker chip, a planet with a mass BILLIONS of times that of the Excelsior (much less a star with an additional few million or so times as much mass) would be completely unaffected.

Corrected entry: Captain Kirk and Dr. Mccoy escape from the Dilithium mines together with the shape shifter. They go to the surface and get out of the magnetic shield that prevents Enterprise from beaming them up. When they fight and get discovered later, it seems it is all a setup and they are beamed up by Enterprise just before they are shot. But why did the shapeshifter lead them to a place outside the magnetic field? If only they were inside it (no markings around to show they are outside the field), they could never have been saved.

Correction: The Klingons (for whom the shapeshifter is working), need a reason to shoot/kill Kirk and McCoy. I know, I know, Klingons don't normally need a reason to kill something, but this is a special case. Kirk and McCoy weren't killed after their trial as a peace gesture to the Federation. Killing them inside the shield, from which they can not be rescued, would be seen by the Federation the same as executing them. By them being outside the field, where they can escape, they are fair game to any prison warden. The Federation would understand that their death was acceptable under the circumstances and the summit on Khitomer would continue as scheduled, giving the conspirators a chance to kill the Federation president, just as they killed the Klingon Chancellor. They've been trying to start a war the whole movie, but Kirk keeps getting in the way, by trying to save Gorkon, by actually escaping from Rura Penthe, and then by disrupting their attempt on the President. Without actions of the crew, the conspirators would have succeeded.

Corrected entry: In the beginning of the movie, Sulu's Captain's Log (voice-over) tells how his ship, Excelsior, is cataloging gaseous anomolies. Later, when the Enterprise has no way to fire back against a Klingon ship that can fire while cloaked, Ohura says, "What about all that equipment we're carrying to catalog gaseous anomolies?"

Correction: Why can't Enterprise be on the same mission as Excelsior? Starfleet has hundreds of ships, surely 2 can be doing the same thing simultaneously.

Grumpy Scot

Corrected entry: Throughout the movie, and including the climatic battle sequence between the Enterprise and General Chiang's Bird of Prey, Scotty is wearing his black "casual" duty uniform. When Kirk and company beam down to Kitimer, Scotty is wearing his red uniform. When they return to the Enterpise, he's back in his black uniform.

Correction: Scotty just put on his red uniform jacket over his black utility overall top. He took it off when he got back. The pants are the same.

Grumpy Scot

Corrected entry: When communicating with the Klingon vessel, Uhura uses a book to search for the correct words and translation. She can't use the universal translator to do the job for her, because the Klingons would recognise that. Why doesn't she use the universal translator as example and then simply repeat it to the Klingons, instead of making a mess of it with the books?

Correction: The universal translator doesn't work that way. As revealed on the DS9 episode "Little Green Men", the UT is an aural implant that changes the soundwaves to the correct language for the user. If Uhura speaks in direct Klingon, the UTs the Klingons have won't have to do any work and it would sound more natural to the Klingons than if Uhura spoke her native Swahili (which, according to the ST universe, is what she's usually talking in) and had it translated.

Corrected entry: Towards the end of the film when the Enterprise is under attack by the invisible Klingon ship, Spock asks Dr. McCoy if he'd like to perfom a surgery on a torpedo to enable it to detect the plasma emitted by the Klingons. But McCoy is a medical doctor and can hardly be qualified for this work. Why doesen't Spock just ask Scotty, who is also present and doesn't have anything else to do?

Correction: Scotty isn't really available at that time. He's busy with keeping up the shields. Besides, there isn't very much time to look for someone else, and, all Dr. McCoy has to do is hand over some tools at Spock, so he doesn't need very much of a qualification for that.

Corrected entry: In begining of the movie, a moon in the Klingon home system explodes, sending out a shockwave that travels across Klingon space, across the neutral zone and into Federation space to hit the USS Excelsior so fast that it wasn't detected before it hit the ship. First of all, the shockwave should be restricted to the speed of sound, it would have taken years to arrive to the Excelcior's location and second, in the movie S.T.: Generations, a shockwave from a collapsing star takes several minutes to hit a space station in the same system.

Correction: The "speed of sound" is only important when there's some kind of medium that can carry sound waves, since sound is nothing but vibration of the medium's particles. In space there is not such a medium. So: no medium, no sound, no speed of sound. Based on that, the speed of sound cannot be a limiting factor for the shock wave's speed. In fact, it is said in the movie that it is a "subspace shockwave." We can assume that subspace shockwaves can move faster than the light, since the warp drive which is based on subspace distortions allows faster-than-light-travel. All in all - no mistake.

Corrected entry: Years of dispute with the Klingons, and Federation engineers haven't managed to circumvent the cloaking device - yet a 100% effective torpedo is built on the Enterprise by a doctor, during a battle, using instructions from a radio-operator, in under 10 minutes. Makes you wonder why Starfleet actually has engineers.

Correction: Spock was with McCoy when they were modifying the torpedo. It's true that the engineers should have discovered this earlier, but Uhura points out that Enterprise is currently carrying extra equipment for studying gaseous anomalies.

wizard_of_gore Premium member

Corrected entry: When communicating with the Klingon vessel, Uhura consistently mispronounces the Klingon word for 'over.' The Klingon she's speaking to pronounces it 'reen.' Uhura keeps pronouncing it 'ren.' The mistake is relevant because they're speaking Klingon directly to avoid being recognized as a Starfleet vessel.

Correction: Seems more like a "you say po-tay-toe, I say po-tah-toe" thing. Like saying "yeah" vs. "yes". After all, the Klingons still bought it.

Grumpy Scot

Corrected entry: During the scene in which Bill and Admiral Cartwright discuss Operation Retrieve with the Federation President, the person who briefs the president on Operation Retrieve is called Colonel West. But when you look at West's uniform closely, it can be seen that he carries the rank of Admiral. And according to many Star Trek sites, the rank of Colonel doesn't even exist in Starfleet's ranking system.

Correction: Gene Roddenberry suggested that there are Starfleet Marines. We even see them in DS9. Colonel West could be one. Doesn't explain the Starfleet Naval uniform unless he was undercover for some weird reason.

Grumpy Scot

Corrected entry: The shapeshifting woman at the dilithium mines where Kirk and McCoy are sent changes her shape often to a big monster, small child, etc., but her voice always remains the same. However, when she takes Kirk's shape she also takes Kirk's voice.

Correction: We also see that she can change her voice before then anyway. When she is leading them through the mine, just before changing into the little girl, she calls out something to the klingon guards in a voice that is most obviously different from her regular voice. She probably didn't change her voice when speaking with Kirk and McCoy simply because they would not have recognized her otherwise, but she was playing with them when she changed into Kirk.

Captain Spock: If I were human I believe my response would be "go to hell." If I were human.
Commander Pavel Andreievich Chekov: Course heading, Captain?
Captain James T. Kirk: Second star to the right and straight on till morning.



When Captain Kirk and the shape shifter are fighting on the planet (the shape shifter looks exactly like Kirk). They are rolling through the snow about to roll over Bones. In one shot, it looks like they will roll over his feet first, and then the rest of his body. In the next shot, it is a little closer and they roll over Bones' right arm first and not his feet first.



Both the opening explosion of the Klingon moon Praxis and much of the footage from the U.S.S. Excelsior was later used in an episode of "Star Trek: Voyager", ("Flashback") with special guest star George Takei.
