FH and GF: Scorsese played a character named Shorty (Charlie calls him "Shorts"). He's in another scene: Charlie's on the street outside a storefront, talking to Michael, and there's Shorty. Charlie, ever the diplomat, says, "Hey, Shorts..." and Shorty says, "F*** you, Charlie!" or something equally hostile. You wonder who he is and what he's doing with Michael. Then he shows up in the backseat of Michael's car, with the gun...
Nick, you've never seen "Goodfellas"? Oho, are you ever in for a treat!!!
