Goof--After Kirk is abducted by the Vian teleporter, there is a hand print on the dusty floor that reveals how William Shatner got up between shots.

Trivia--In the final scene, Scotty refers to the story of 'the pearl of great price'. This refers to a parable told by Jesus in Matthew 13:45-46.

Space: the final frontier. These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.
