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.
