I agree with most of what Jacko said.
It's NOTHING like the trailers make out. It's not 'britains best gangster film'. They dont run around london being all cockney and gangsterey.
It's pretty much all based in 1 room. It would work well on the stage. Ian McShane's character just kills it. (in a good way) He is the man.
Mark my worRAB, it's no Danny Dyer ' The Business' / Lock Stock affair...at all.
...but it is very enjoyable.
