Joe Pesci getting beaten and buried on top of his brother in Casino takes the cake.

That movie was pretty violent, what with Joe Pesci STABBING A GUY IN THE NECK WITH A PEN. That was the second most violent scene in that movie. I mean, that's f*cking brutal!

Goodfellas, when theyre kicking the guy to death in the bar was kinda shocking. And then Pesci stabs him in the trunk of the car...

The ending to Mean Streets wouldnt be that bad if it wasn't so realistic. DeNiro running around with a bullet in his neck or whatever, and the girls arms is sticking out of the windshield.

Gangs Of New York, when Bill the Butcher bashes the guy in the head with the mallot is pretty bad, too.

Martin Scorcese is a violent guy!

And if anyone saw Carlito's Way, the part when Sean Penn (the lawyer) bashes the Mafia boss on the head until it breaks open and blood pours out was surprising violent for that movie.
