Revealing mistake: When Kirk and Kruge are fighting, a piece of the cliff breaks away and wiggles down the side of the cliff rather than falling like a rock. (01:22:55)
Captain Spock: My father says that you have been my friend. You came back for me.
Kirk: You would have done the same for me.
Captain Spock: Why would you do this?
Kirk: Because the needs of the one... Outweigh the needs of the many.
Captain Spock: [begins to remember] I have been and ever shall be your friend.
Kirk: Yes. Yes, Spock.
Captain Spock: The ship... Out of danger?
Kirk: You saved the ship. You saved us all. Don't you remember?
Captain Spock: Jim... Your name is Jim.
Kirk: Yes.
Trivia: On the backside of the DVD near the bottom is a series of six images purportedly from the movie. The second image shows the crew in uniform, including Mr. Spock, standing in the Federation Council chamber. This image comes from the movie Star Trek IV: The Voyage Home (after the crew has returned to Earth and is waiting to hear the Council's judgment).
Chosen answer: Kruge only had the proposal video that talked about what Genesis was. He didn't have any actual data on how Genesis works or how it could be created. Having footage of a nuclear blast doesn't give you knowledge about how to build a nuclear device.
