Continuity mistake: When Khan contacts the Enterprise after Reliant's opening attack, Kirk has his uniform jacket unbuttoned to about mid-chest level (a little above his stomach). When Khan demands all information on Project Genesis be turned over, and Kirk responds with 'Genesis? What's that?' his jacket is now unbuttoned all the way down to his belt.

Trivia: As the shuttle with Kirk and company approaches the Enterprise in Space dock, Sulu says "I'm delighted. Any chance to go aboard the Enterprise..." According to IMSDb.com, there was a full dialog between Kirk and Sulu in the original script. The rest of Sulu's line was "however briefly, is always a chance for nostalgia." Kirk also told Sulu the he had cut the orders for Sulu to Captain the Excelsior.
Question: When Khan speaks to Kirk, he tells him that he wants revenge for the death of his wife. Who was Khan's wife?
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.
Answer: Lt. Marla McGivers was the crew member.
