That character was magnificently played by Ben Kingsley as Don Logan. Logan was the very embodiment of a sociopath, a fuming, steaming, spiting, cursing Tasmanian Devil with Tourettes; a gangster Sergeant Major that simply would not take no for an answer.

Shut up, cunt. You louse. You got some fuckin' neck ain't you. Retired? Fuck off, you're revolting. Look at your suntan, it's leather, it's like leather man, your skin. We could make a fucking suitcase out of you. Like a crocodile, fat crocodile, fat bastard. You look like fucking Idi Amin, you know what I mean? Stay here? You should be ashamed of yourself. Who do you think you are? King of the castle? Cock of the walk?
Jeff is such a Sexy Beast that looking at him makes me want to be on the show.
