You young ones wont remember this but this is better than Lock Stock and all the other so-called British "gangster" movies by a country mile! Another one of my HMV purchases before it goes bust, what a classic!
Stars Bob Hoskins, Helen Mirren, Pierce Brosnan, Alan Ford... awesome. Highly recommend. Released 1980.
