This adaptation is focused on slapstick comedy out of the main characters, instead of fine trickery and con-artistry tailored to secondary characters. The story itself is more dramatic. The protagonists are actually not really bad people. One is a poor and simple barber, the other is a chancer and a gold-digger, but also is not that greedy and does bankroll the whole operation. Their dynamic is also spruced up with light flirting. By the end she got nothing and he got an existential karmic ending. For his greed, serial cases of minor vandalism, and being rude to the dead he got a religious epiphany and went from being poor to be complete hobo. The setting of the film also adds some flavour.
The gynecologist scene is kind of shabby though. All they had to do is let the next in line in.
