Corrected entry: When they discover that the Genesis device has been activated, Kirk volunteers to beam over to stop it. Even though he is told it can't be stopped, that would indicate the transporters are still working. Why does nobody suggest beaming the device itself off of the Reliant and out into space with the widest possible dispersion, like they did in "Wolf in the Fold" to Redjac?
Corrected entry: Maybe not a mistake per se, but certainly odd: A sign posted at the rear of the bridge says "No Smoking On The Bridge At Any Time." A good idea to be sure, but at no time in any incarnation of "Star Trek", whether the TV versions or the theatrical releases has any character ever been shown to smoke anything. Gene Roddenberry' Utopian vision of the future didn't include any of our contemporary vices, so it is odd that a sign like this would ever be posted. However, it's possible that this was simply a warning to the cast and crew on set, and had no impact on the fictional characters and their universe. [This was actually a deliberate act on the part of the director, Nick Meyers. He likes putting elements that give a common, real-world sense to them. He's also the one that gave the crew bunk beds in Star Trek VI: The Undiscovered Country.]
Corrected entry: When Spock dies, the left side of his body and the left side of his head rest against the transparent shield. In the next scene, the back of his body and the back of his head rest on the shield. The position of Captain Kirk relative to the position of Spock also changes between these scenes.
Corrected entry: When Chekov calls Dr Carol Marcus about coming to take the Genesis device (after being subdued by Kahn) there is a science tech in the background, he is African American. Watch him, and his reaction to Chekov's statement about coming over to Regula One. At that point Chekov has mentioned just coming over. The techs reaction is one of questioning annoyance, he then darts his eyes realizing that he's reacting to the right thing at the wrong time.
Corrected entry: Khan claims to have remembered Chekov from "Space Seed", which ran during the series first season, but the character of Chekov wasn't created until the second season of the series.
Corrected entry: The scene where Checkov first goes to Khan's cabin on the planet, he notices a belt with "Botany Bay" and realizes it is Khan's cabin. This film is based on TOS-"Space Seed," however Checkov was not in "Star Trek" when this episode was made. How would Checkov know about the ship "Botany Bay"?
Corrected entry: After the Enterprise first attacks Reliant and they have moved away, Kirk says "Let's see how bad we were hurt". Then Scottie is seen coming out of the lift with a wounded crewman. Wouldn't it be better to take him to sick bay? Sickbay is in the upper (circular) hull, but is on a lower deck than the bridge. There's no sane reason why Scotty would bypass the deck where Sickbay is to go all the way up to the bridge in order to get help in carrying the wounded crewman back down again.
Corrected entry: Khan wears a damaged 'Starfleet' emblem on a chain around his neck during this movie, obviously a souvenir from the last contact he had with any Starfleet personnel, which was Kirk and company back during the original TV episode 'Space Seed'. However, the emblem that Khan wears was not in use by Starfleet (either on the Enterprise or fleet-wide) at the time of his 'release' on Ceti Alpha V, as it came into use much later, during the 'Star Trek-The Movie' era. (Reportedly about 11 years after the ending of Kirk's original '5 year mission'). So where did Khan get the emblem?
Corrected entry: After beaming down to Ceti Alpha V (thinking it is C.A VI) and entering the cargo hold, Chekov notices the words "Bottany Bay" on one of the straps. This means that they are actually in part of the ship that Kahn and his followers were found in. How? That ship was ditched in the episode Space Seed well before they decided to drop Kahn and his followers off at the planet.
Corrected entry: In every battle that results in major ship damage getting warp drive back on-line is always a priority. If it was so easy for Spock (in the sense that he did not need any tools and not easy in the sense that he died) to get warp drive back on-line why didn't somebody else (with full protective gear) do exactly what he did a lot earlier? Also, what did he do?
Corrected entry: In the original pre-screening of the film, the audience was furious over the death of Spock. This left the creators with the thought of "what have we done?" Their solution: shoot an extra scene in which Spock hits McCoy with a nerve pinch, transfers his 'living spirit' into the comatose doctor, and then insert it into the movie prior to the point in which he puts on Scotty's gloves and steps into the reactor room.
Corrected entry: At the very end of the movie, as the Enterprise finally jumps into warp, and away from the Genesis explosion, we see a huge explosion, and then we see the Enterprise, racing at warp speed. If the Enterprise were traveling at warp speed, which remember is Faster-Than-Light, then we would have seen the Enterprise first, THEN the explosion.
Corrected entry: Khan is able to capture the starship Reliant because Chekov and Terrell beam down to Ceti Alpha V, mistakenly thinking it's Ceti Alpha VI, where Khan takes them prisoner. Khan explains that Ceti Alpha VI exploded. Ceti Alpha is obviously a known solar system. Nobody aboard Reliant, not the helmsman, navigator, nor science officer, noticed that there was a whole planet missing from the system?
Corrected entry: After beaming down to Ceti Alpha 5, Chekov discovers the SS Botany Bay name tag and says, "We've got to get out of here". They put on their helmets and go outside. Judging by past Star Trek movies/episodes, why wouldn't they have used the "Beam me up quick" method instead? The Botany Bay's cargo containers were sitting on the surface, not underground, so there shouldn't have been a problem.
Corrected entry: When Spock administers the Vulcan Neck-Pinch to McCoy in Engineering (just before he enters the radiation-contaminated area), McCoy grimaces, then sinks to the floor. When Spock is delivering his lines of, "I'm sorry doctor, I have no time to discuss this logically" McCoy's eyes flicker open, and he actually looks toward Spock's approaching hand when he is about to mind-meld with him.
Corrected entry: Chekov was not part of the original crew during the TV episode of "Space Seed", but in the movie Khan acts like he knows him and Chekov not only knows the name of Khan's ship but he also knows what happened.
Corrected entry: When the Enterprise first encounters the Reliant, we see several screen shots of the Reliant on the Enterprise viewscreen, and several shots of the Enterprise on Reliant's viewscreen. The puzzling thing is, if you watch very closely to the shots of the Enterprise on the Reliant's viewscreen, you will notice that the stars are actually moving BACKWARD, as if the Reliant were in a slow reverse. Obviously this is an editing blooper since Khan just ordered that the ship slow to one half impulse power, which still moves the ship forward.
