Legend is the real life story of the Kray Twins. They were the gangsters of 1960's London, taking control of nightclubs and casinos by force and intimidation. The story itself of Legend is one we've seen before, the rise and fall of the gangster, but Tom Hardy is so damn good as both the charismatic Reggie Kray and the insane Ronald Kray it injects a new level of energy into the film.
The supporting cast of Legend is also good, featuring Emily Browning, David Thewlis, Christopher Eccleston, and America's favorite movie star gangster, Chazz Palminteri (A Bronx Tale). All of them play their parts well, creating believable characters that we relate to and feel sympathy for. The only real problem with this movie is that it doesn't go anywhere after it introduces us to these characters. The film follows the rise of the Krays and the inevitable fall, and that's just how everything that happens after the midpoint of the film feels, inevitable. There are very few twists in the story to keep us engaged, and the weight of it all falls onto Hardy's shoulders, but luckily for the film Hardy actually manages to hold it up.
