Directed by: Robert Wise
Starring: William Shatner, George Takei, Leonard Nimoy, Walter Koenig, DeForest Kelley, James Doohan, Nichelle Nichols
Continuity mistake: In the final scene on the bridge, Spock and McCoy are wearing coloured arm bands which identify their departments: Spock's is orange (for Science) and McCoy's is green (for Medical). In the very last shot, Spock is wearing the green band and McCoy is wearing the orange one (corrected in the 2022 re-release of the Director's Edition).
Continuity mistake: In the original series Spock mentioned that Vulcan has no moons. In the movie, when Spock is on Vulcan, he looks up and shields his eyes against the glare of the sun. When the scene changes, it is night and there are moons. (Corrected in the Director's Edition).
Suggested correction: Though the planet had no moons, it did form a binary pair with T'Khut and was considered its sister planet. From Memory Alpha.
Spock: Each of us... At some time in our lives, turns to someone - a father, a brother, a God... And asks..."Why am I here? What was I meant to be?"
Trivia: If you look at the Kholinar necklace Spock was to be given when he was on Vulcan it bears a striking resemblance to the Enterprise, especially when it is laying on the ground before Spock picks it up.
