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.
Corrected entry: Kahn explains that Ceti Alpha VI exploded and altered the orbit of the Ceti Alpha V, laying everything waste on the planet. Okay, fine. How then did they mistake Ceti Alpha V for Ceti Alpha VI? Star Trek has established that their method for numbering planets is based on orbit position numbering outward from the star at the center of the system (Earth would be Sol III if it didn't already have other names). For Ceti Alpha V to be mistaken for Ceti Alpha VI, there would have to be another planet inserted between Ceti Alpha V and the star (Ceti Alpha). There is no way for an explosion at Ceti Alpha VI to send a new planet in past Ceti Alpha V and the only way for the explosion to push Ceti Alpha V away from the star would be if the planet had exploded while on the other side of its orbit from Ceti Alpha V. If that had happened, the shockwave would not have been nearly enough to sent Ceti Alpha V up two orbits (because Ceti Alpha VI is gone so Ceti Alpha V would have to go up past Ceti Alpha VII).Garlonuss
Corrected entry: When Enterprise finally defeats Khan in the Motara Nebula, Uhuru starts transmitting the order to surrender for one minute and 18 seconds before Khan activates Genesis. That was more than enough time for the Enterprise crew to beam Khan on board the enterprise and either arrest or kill him. (01:28:48 - 01:30:06)
