From the Oscar-winning director of "Slumdog Millionaire" comes a thought-provoking film about an American mountain climber who amputated his own arm.

The film is based on the true story of Aron Ralston, the American mountain climber who amputated his own arm to free himself after being trapped by a boulder in Robbers Roost, Utah for nearly five days in May 2003. James Franco (Spiderman) stars as Ralston. The film will be released in the United States on November 5, 2010.

The film is written by Danny Boyle and Simon Beaufoy and produced by Christian Colson, who previously teamed up for Slumdog Millionaire. The film’s score is composed by Boyle’s previous collaborator on Slumdog Millionaire, A.R. Rahman.
