1) The Escapist

2) A Very British Gangster
( documentary, Sundance nominee )

yes I was going to add this.

very underrated and made by the same guy who went on to do slumdog millionaire..

Also look for one called "Love Honour and Obey" - an earlier one with Ray Winstone, Jude Law, and others.

LOL crank is about the shittiest movie I ever did see. Why Jason Statham disgraced himself with that pile of utter horseshit is beyond me :2 cents:

edit : it's also not british. and did I mention it's shit?

Trainspotting
Cass
Rolling With The Nines
Rise of The Foot Solider
Bullet Boy
Sugarhouse

Hot fuzz

yes this is also excellent....

plus look for anything by Shane Meadows -

Dead Mans Shoes
This Is England
A Room For Romeo Brass
Once Upon A Time In The Midlands (not quite so good)

28 days later and 28 weeks later if you like zombie films.

Trainspotting
Chariots of Fire
A Fish Called Wanda
A Clockwork Orange

Before Sunset/Before Sunrise - Not British but great films.

The Long Good Friday (1980)
Scum (1979)
Alfie (1966)
Get Carter (1971)

The Bank Job

Yeah 28 weeks later is the sequel. I think there is a third coming out which is going to be set in Russia.
