Also, for those who don't know.
Tommy's Mother was Scorsese's Mom
The guy on the left, who doesn't kill Tommy, was Scorsese's Dad
One of the most satisfying death's ever, despite being a GREAT character. The only difference was that the real Tommy was way younger and even more batshyt insane. It's shocking yet deep down it was excellent, because Tommy had it coming for being a fukk up.
Scorsese's parents had little cameos in a lot of his films up until they both died. I could always recognize her b/c she look like Martin with a wig on but the pops I could never spot. And they usually didn't appear together.
