Best line comes from the tortured Keith character who says:
"You don't know me well enough to hate me that much. Hating's a subject I know a little something about. You better be careful it don't bite you back. I know somebody spent five years looking for a man he hated. Hate and wanting revenge was all that kept him alive. He spent all them years tracking that other man down. When he caught up with him was the worst day in his life. He'd get his revenge, all right. Then he'd lose the one thing he'd had to live for."Early Sam Peckinpah (The Wild Bunch, Ride the High Country) though you would hardly know because he had very little control over the finished product.
