Godspell (1973)

Revealing mistake: Part of the concept of the film is that, save for Jesus and his disciples, Manhattan is deserted for one day. However, during the baptism scene in Central Park, you can see a horrified man in the lake on a boat, desperately trying to row out of the scene.

Jesus: Hey.
Judas: You come to me?
Jesus: I want to get washed up.
Judas: I would rather be baptized by you.
Jesus: No, we do well now to comform with all that God requires.
