Speaking of alumni of mob actors, if you are a Sopranos fan and have not yet seen Gotti, it features Vincent Pastore, Tony Sirico, and Dominic Chianese. It is also in my opinion a pretty decent movie, and worth a view regardless of whether or not you're a Sopranos fan. I thought Armand Assante played a pretty damn good Gotti.
