Whats that Italian movie about the boy named si or C?

Its a movie i saw on tv yesterday and i never got the name of it. It was about a boy that is given the name C by this mobster/ bar owner named sonny and C's father is a bus driver in the film. C has a crush on this african american woman which he first saw on his fathers bus, and her name is Jane Williams I think. If anyone knows what i am talking about please give me the name of this movie Thanks :D
