First I heard of it. There are many hours of all three that were put on the cutting floor.
Turnbull, that scene with Paulie and two heavies was put in the game, your character also is the one that does the beating, with Paulie at the end knocking the kid out with the shovel and landing in the grave.
Another scene is showing where Luca lives and hurting someone that is behind on their payments, again your character does the fighting.
