Late in, my apologies.
However, I once ran a street-gang / organized crime campaign based on the movie "King of New York" with Christopher Walken, Laurence Fishburne (Morpheus) and Wesley Snipes. Converted them all into relevant archetypes and let it roll. It was incredibly violent and visceral. Even to this day my players curse the names of those bad guys.
Dont forget that similar movies can inspire great story arcs. "Man on Fire" or "Training Day" or even "American Gangster" are potential sources of future runs.
