I read somewhere that a lot of mafia people were around in the sets (those shot around the streets) when the film was being made. I am not talking about the big guys here, they were the street level operators. They were happy that a film glorifying them was being made and many of them went to watch the movie. But they realized that once the shooting was done, all their celebrity status was lost. I don't remember where I read this, it was actually an old review. Written around the time when the movie was released. I vaguely remember that someone on this boards posted a link to that. Not sure...
