Other mistake: On board the USS Reliant as it orbits Ceti Alpha 6 the systems panels show ship diagnostic diagrams including a wire model of a Constitution class hull, something the Reliant doesn't have. (00:13:01)
Other mistake: During many of the scenes of the Reliant in space, you can see stars through the dark parts of the engine nacelles.
Other mistake: When Captain Terrell shoots himself with the phaser, the phaser disintegrates along with his body, when it should have just dropped to the ground (as often shown in the various Trek TV shows). It wouldn't make sense to explain that the phaser disintegrated because Terrell was touching it, because then it would be impossible to explain why nothing happens to the ground that people are standing on when they get shot (Director's Cut). (01:11:20)
Teru_KageOther mistake: After the Enterprise blows the port nacelle off the Reliant, the destroyed Reliant bridge is shown. The three sheaves of wires hanging from the ceiling should be on a tilt with the angle of the ship rather than straight down. Even accounting for the artificial gravity unit, which could have been damaged.
Movie NutOther mistake: As the turbo lift doors open for Joachim to say his line, the diagram of the lift system on the back wall is of the Enterprise's system.
Movie NutOther mistake: On the Reliant, as the woman turns and goes to activate the transporter, the blue diagram on the monitor above and to the right of her head is the port and top diagnostic views of the Enterprise, rather than the Reliant.
Movie Nut
Answer: This is a reference to the TV show episode that this movie is a distant sequel to. In that episode, one of Kirk's crew falls in love with Khan and helps him take over the ship. When Khan is exiled to the planet, she chooses to go with him. So it would be that after the catastrophic events of one of the planets in that system exploding and causing all sorts of damage to their new planet, she was killed there and Khan blames Kirk for it.
