I go with two el-cheapos from the '50s: "Inside the Mafia," with Cameron Mitchell playing a mob boss; and "I, Mobster" with Steve Cochrane (winner of the Elvis Look-Alike and Hair-Grease Contest) as the mob boss. To give you an idea of how campy-bad these flicks were: Robert Strauss plays a Mafia guy in both, and in "Inside the Mafia," he uses karate.
