I watched Boiling Point recently, very good film, and I realised this guy has never disappointed me in any performance, ever. Even if the movie itself is shit. He's a wonderful character actor on the same level as Gary Oldman. I'll watch anything he's in.
Yeah he's very good, been in a bunch of gangsta flicks. He even played Sammy the Bull in a tv biopic of the same.
Just finished rewatching Boardwalk Empire - he was excellent as a young Al Capone. If I didn't already know I'd never in a million years guess he's British from that performance.
He's fantastic in so many films and any series I've seen him in. Tough to say which is his greatest performance, as there's so many, but Combo in This is England is right up there. He also plays an alcoholic in The Virtues. Very hard-hitting series.
