The actor has been cast in Danny Boyle's upcoming 127 Hours, based on the true story of climber Aron Ralston who was forced to saw off his limb after a boulder fell onto him while he was climbing in Utah in 2003.
Ralston was trapped in the canyon for five days before he used a blunt knife to free himself and was eventually rescued by helicopter.
Filming is scheduled to begin in March in Utah.
