Audio problem: In the shop scene at Ginsberg and Cohen's, when Miles replies, "Something simple," he never opens his mouth to do so.
Continuity mistake: At the beginning of the scene in which Diane Keaton rides on Woody Allen's back across the water, she is wearing clunky platform shoes.

Visible crew/equipment: The boom mic is visible while Miles is describing the artifacts from the 1970s.
Visible crew/equipment: The tow cable for the raft costume is visible.
Visible crew/equipment: When Woody is trying to escape with the flying device (the one that mounts in the back) the tow cables are visible in one shot.
Continuity mistake: When Woody is stuck in a tree, he is wearing blue jeans, but both before and after that, his pants are black.
Revealing mistake: Diane Keaton's stunt double is obviously a man during the scene where Luna swings across the stream and into a tree.
