Ralston used a blunt knife and pliers to amputate his right forearm after it was pinned between a boulder and the canyon wall for nearly five days, reports The Mirror. The mountaineer documented his experience in a book entitled Between a Rock and a Hard Place. He has also appeared on US talk shows and is now a corporate speaker. The production of the film is due to begin in 2010 and is expected to release late next year.
