I can't choose only ONE film. I love the 3 GF films and Once Upon a Time in America more than the others I've seen.
Yes, Scarface, the De Palma version, is NOT a mob movie. Tony Montana is alone, he's a business man and has no organized mob which whacks ppl on his orders, he "just" make business with cocaine. On the contrary, the original Scarface from 1932 WAS a mafia movie.
