It would be great. You could have classic gangster movies... all the old Cagney and Edward G. Robninson movies....Cop movies with gangsters, comedy Gangster movies like Some Like It Hot, The Freshman, etc, All the contemporary gangster movies, Scorsese movies Scarface, etc, and of course the Godfather.
I'd set it up so that every Saturday or Sunday night was Godfather Night. Showing 1, 2, 3, and also showing it a few times a year in the chroological version....do all kinds of interviews with the cast and FFC.
Also documentaries about real gangsters.
