Correct me if I am wrong but I think I read an interview of him one day. He was talking about "mob culture" in the mainstream, and singularly among Italian Americans. He was retelling a moment in his life when one of his gangster characters became a police informant. After seeing the scene on TV, his grandson allegedly stopped talking to him for days in disgust that "old grandpa was a snitch".
Otherwise, I've loved him the most in Casino. There is this one particular scene in the corn field....
SPOILER
...during which he tortures and buries his friend alive. The violence notwithstanding, what is especially touching in this scene is that both of them come a very long way. You've seen them do everything together during the movie's entire duration, and yet he has to perform this horrendous act of betrayal because he was ordered to (and
he would have been the one tortured and buried hadn't he complied). The look he gives to the body of his friend, lying in the hole, still breathing, just before covering him; it is top-notch acting. In one look, we can see all the emotional conflict at play inside him, making the scene especially powerful.
Best of all, the character's name was... Frank. Way to make Mr Vincent unforgettable, Mister Scorsese!
