When he kills Brumby
That scene was laughable. The way he just keeps hitting, saying something, hitting him, saying something. It was just funny. Then he just lifts him up over the ledge and off the building. It's like the whole scene was done in slow motion. He slowly beats him up and slowly throws him off the building.
In the Get Carter remake, when Jack goes after Eddie, it's a lot like this scene, but done so much better. Eddie says, "Jack, don't kill me, man." Then Jack says, "You killed yourself." Then it cuts to him leaving with the sound of a car alarm going off. You can see Eddie dead on the car.
