Once Upon a Time in America (1984)

Continuity mistake: In the first 1968 section, where Noodles rents a car and drives back to his old neighbourhood, watch the background of the wide shot as he is stopping the car. In the close-up that follows when Noodles gets out, two girls have appeared, hanging around a doorway, who were not to be seen the moment before.

Continuity mistake: When Noodles is raping Roberta in the car, her socks are pale brown-grey, then camera angle changes, and they are black, and then they are grey-brown again.

Revealing mistake: When a man is shot in the head, the bullet hits his hat, and it's very obvious there's no real bullet wound, his hat just opens and reveals a red hat he's wearing.

Police Chief Aiello: I'm the chief of police, not the chief of the people.

Young Noodles: You'll put up, and you'll shut up! You hear nothing, and you see nothing! Just like you did for Bugsy.

Officer 'Fartface' Whitey: Okay, boys, we're even.
Young Noodles: The hell we are.
Young Max: You'll be collecting your pension before we're even.

Question: why, being there so many sequences of nudity in the film, the woman in the funeral car Max brings for Noodles after he is released from jail has her breasts blurred?, why would this scene be conceived like that?.
