Prizzis Honor - a black comedy with Jack Nicolson

Valachi Papers - old Charles Bronson film - not great filmmaking but important for historical reasons as Joe Valachi was one of the first guys to break omerata.

Scarface (Pacino's version)

New Jack City - hey if scarface is there include this

Mean Streets - I never liked it that much, as it looks like a precursor to the great Goodfellas. I might have liked it if I had seen it before Goodfellas.
