Gangster No. 1

This story follows the violent rise and fall of the title character, an unnamed East End London thug (played by Paul Bettany and, at a later age, Malcolm McDowell) who gets hired by high-profile gangster Freddie Mays (David Thewlis). The eager young gun -- an irredeemable, inhumane psychopath obsessed with power -- eventually replaces his boss as top gangster by way of lies, manipulation and murder.
