Breaking Away (1979)

Continuity mistake: There is an error in the scene where Dave is drafting behind the Cinzano truck. In the second close up shot of his legs (cranks) pedaling the bike he is in a lower (easier) gear than the previous shot even though he is supposed to be riding significantly faster.

Continuity mistake: In the climactic race scene near the end, every time the camera cuts back to a long shot of the race, the lap number on the board goes up and down, rather than going up sequentially.

Continuity mistake: In one of the shots where Dave Stoller is chasing after the girl to return her notebook, we see him riding his bike in front of a building. In the next shot he is riding in front of the same building, going in the other direction.

Dad: Refund? Refund? Are you crazy! Refund? Refund? Refund?

Dad: I dreamed all last night, that everyone I ever sold a car to came back for a refund. And there you were, handing out the checks! One for you, and one for you.

Cyril: When you're 16 they call it Sweet 16 and when you're 18 you get to drink and and vote and see dirty movies. What the hell do you get to do when you're 19?
Mike: You leave home.
Cyril: My Dad said that Jesus never went further than 50 miles from his home.
Mike: Well, look what happened to him.
