I noticed that this forum has been a little dead recently, so I figured I'd add a thread I've never seen done before.
I was rewatching Mask of the Phantasm and Subzero and I noticed a few cool snippets of information that I never noticed before.
-In Mask of the Phantasm, Sal Velestra, Buzz Bronski and Chuckie Sol look exactly like The Godfather's Vito Corleone, Pete Clemenza and Sal Tessio, respectively.
