the actor who plays Jimmy Whispers in "A Bronx Tale" appears in Goodfellas as 1 of the men working on the heist project. I think he also appears in Analyze This is an asassin hyred by Chazz Palminteri to murder Paul Vitti played by Robert Deniro. Chazz and Rob have made appearances/starred in both A Bronx Tale and Analyze this.
