Star Trek IV: The Voyage Home

Other mistake: After they take off from California, Kirk gives a heading to Alaska. He then tells Sulu "full impulse power", and Sulu says "aye, ETA 12 minutes." Full impulse is 1/4 the speed of light. No way they would use speeds like that to go a few thousand miles.

Continuity mistake: The Bird of Prey is the one captured by Kirk's crew in ST III That ship's bridge showed Klingon Cmdr Kruge in his elevated command chair with his helmsmen arrayed circularly below him, and nothing else. ST IV has this same ship, however the bridge now resembles The Enterprise layout with Kirk's command chair behind Sulu and Chekov at their rectangular helm, with Spock, Scotty and Uhura at their usual positions.

Suggested correction: According to the captain's log at the beginning, they have been on Vulcan for 3 months. As they prepare to depart, we see several Vulcan technicians moving equipment in and around the ship. It's quite conceivable that the bridge was reconfigured according to the crew's specifications to facilitate their use of the ship. This may seem a bit excessive, as the remodel includes the door onto the bridge, and the frame of the door, and possibly most of the rest of the ship. But it's not outside the realm of possibility. The real mistake, though, is why they would go to the effort of installing new workstations on the Klingon bridge and marking them with Klingon labels, instead of standard Federation text. Interestingly, though, the "Starfleet" style bridge layout of the Klingon ship is being used by the Klingons on the Bird of Prey in Star Trek V.

Visible crew/equipment: In the scene where Sulu flies the helicopter and accidentally turns on the windshield wiper, look closely at the bottom of the wiper and you can see the crewman's finger manually moving the wiper. (01:18:55)

Other mistake: During the inquiry at the start of the movie, the Klingon Ambassador is going over the footage of the destruction of the Enterprise from all the exterior views. This is very nice, but how would they have access to all of these different viewpoints of the destruction? Bearing in mind no-one was there to film it. It couldn't have been the Klingon Bird of Prey that filmed it, because in most of the destruction scenes, the Bird of Prey would have been no-where near or in a position to film it, and was of course captured and still being commanded by Kirk during the course of the inquiry.

Suggested correction: It's possible the Grissom and/or the Bird of Prey launched drones into orbit to aid in the scanning of the planet or for communications or sensor relays, and this is where the footage could have come from. This isn't unlike the beginning of Star Trek: The Motion Picture, in which crewmembers of the space station mentioned such drones as the reason images of the aftermath of the V'ger destruction were able to be seen despite no ships being left.

Continuity mistake: Gillian's Chevrolet pick-up truck is obviously two different trucks, depending on its location. When near the aquarium, the grille is a series of large, rectangular openings. But when at the park, where the Bird of Prey landed, the grille is a much tighter series of more numerous, smaller rectangles, made up of much thinner bars. This difference is consistent through the entire film. (00:55:05)

Continuity mistake: Notice the candle on the table in the Italian restaurant scene during Capt. Kirk and Dr. Gillian dialog. It changes height depending who is talking. (01:03:50 - 01:08:30)

Other mistake: When Kirk uses his hand phaser to melt the lock on the door in the hospital operating room, the phaser is not pointed directly at the lock. The beam leaves the phaser at an angle, which is probably not how the phaser would have been designed to operate. (01:25:20)

Revealing mistake: When Chekhov falls on the aircraft carrier a cloud of dust flies up as if he's landed on a mat or soft cargo. When we see him on the floor it's concrete.

3

Visible crew/equipment: In the scene where Mr. Chekhov is being interrogated on the USS Enterprise (the aircraft carrier) after being caught on board, a studio microphone being used for the shot is visible hanging above him. (01:14:45)

Factual error: When Chekov and Uhura first see USS Enterprise and then later beam aboard, the carrier shown is not USS Enterprise (a nuclear aircraft carrier), but rather USS Ranger (a conventional or oil-fired carrier). The most obvious clue is the "island", the huge structure that sits on the deck of the carrier. USS Enterprise has the most distinctive and unique island of all the USN carriers, being totally cube-like in appearance. The carrier in Star Trek IV has a more conventional style island. [It is true that the USS Ranger was used in lieu of the USS Enterprise for the movie. This is because the Enterprise was on deployment at the time. Though by the time the movie was made the Enterprise had had its distinctive pagoda-like island rebuilt by Puget Sound Naval Shipyard in 1980, the aircraft carrier served until 2012 with a still-distinctive cube shaped island.] (00:53:30)

Continuity mistake: In the operating room, when Kirk uses a phaser to melt the lock, the hand he is holding the phaser in switches hands in the closeup shot. Additionally, the arm holding the weapon in the closeup is no longer in hospital scrubs, but a similarly colored sweatshirt. (01:25:20)

Other mistake: When Kirk sells his "18th Century" reading glasses, a close-up reaveals that the ends of the stems are made of clear plastic- not possible in the 1700s. (00:40:55)

Continuity mistake: When the 'Bounty' materializes right above the whaling ship, it casts it into shadow. But the close-ups of the captain and navigator as they frantically turn the ship around reveal no trace of a deeper shadow on their faces and the surrounding waters; the lighting remains the same as in the scenes when they try to catch the whales. (01:33:45)

Factual error: Scotty is listed in the credits as Captain Montgomery Scott. At the end when the camera pans the crew just before their pardon, Scotty wears the rank pin of a Commander (the same one worn by Commander Sulu, Commander Chekhov, and Commander Uhura). (01:48:55)

Grumpy Scot

Factual error: The "whaling boat" is too small to function as such. It isn't large enough to hold a fin, let alone disassemble a humpback whale.

2

Other mistake: When we first see the Klingon bird of prey on Vulcan (just before we see closeups of the "Bounty" written on the side) it is clear that the ship is far too small to contain a pair of adult humpback whales plus 18000 cubic feet of water in its hold. Later, when the ship is hovering above the sea after foiling the whaling ship's attack it seems considerably larger.

2

Continuity mistake: In the scene where Kirk and Spock are walking down the street after Spock has been in the tank with the whales it is clear that it is a windy day. Both of them have their hair blowing in the wind and yet as they are offered a ride in the truck and the shot leaves them for a moment their hair is suddenly fixed again. (00:55:20)

Factual error: They are about to perform major brain surgery on Chekov, but he is not nearly prepped for such a procedure. His head is not shaved, the area is not marked or masked and it has not been swabbed with Betadine, even though they are about to cut into his skull with a bonesaw. The "they haven't had time to prepare yet" argument doesn't hold water, because the surgeon is already approaching Chekov's head with the saw. (01:24:30)

Revealing mistake: When the whales first swim past the now submerged Klingon Bird of Prey, if you look to the right where the water is supposed to meet the distant horizon, you can see an exposed edge to the 'horizon' as the water moves up and down. This is the edge of the pool they are in, and the exposed edge is the bottom of the painting of the sky behind them. (01:46:30)

Visible crew/equipment: During the scene on the bus, two members of the camera crew are visible in the window behind and to the right of Spock. The crewman of the left is sitting and operating the movie camera, and the crewman on the right is taking still camera shots. (00:43:50)

Spock: They like you very much, but they are not the hell "your" whales.
Dr. Gillian Taylor: I suppose they told you that.
Spock: The hell they did.

More trivia for Star Trek IV: The Voyage Home

Question: When Kirk and McCoy try to rescue Chekov at Mercy Hospital, Kirk removes the 20th Century medical team into an adjacent room and uses his phaser to instantly fuse the metal door lock. The medical team cannot directly see Kirk do this, as they are visibly several feet away on the other side of the door. It's also safe to say that the medical team has never seen a phaser and can't comprehend its function or capabilities. As Kirk turns away from the door to rejoin McCoy, the trapped medical team only then rushes up to the door, and the trauma surgeon exclaims, "He melted the lock!" However, it seems that you'd have to laboriously dismantle the doorknob to determine that the lock's internal components were fused. So, how did a 20th Century surgeon deduce at a glance that Kirk had somehow melted the lock?

Charles Austin Miller

Answer: The lock, and the area around it, would have become hot as a result of melting the lock. The hospital staff would then jump to the conclusion that the lock was melted. The real reason they mention it, however, is so the audience knows what he did to the lock.

But you would think, if the doorknob was still searing hot two seconds after being fused, that the first thing out of the surgeon's mouth would be a scream of pain, rather than "He melted the lock!"

Charles Austin Miller

Answer: The knob would have been super-heated by the phaser blast. Enough that it could be felt without touching, and he simply could have come to the conclusion that a metal object that hot would likely have its internal components melted without a systematic analysis of the doorknob. He's also a surgeon and needs his hands. He wouldn't last long at the job if he was someone who went around putting his hand on glowing-hot doorknobs.
