James Franco had an audience in tears playing mountain climber Aron Lee Ralston, who in 2003 was forced to amputate his lower right arm after it became trapped under a boulder in Utah. At a screening of “127 Hours” hosted by Vanity Fair Editor Graydon Carter, Franco told the crowd that Ralston told him cutting his arm “felt like shoving your entire arm in molten lava.” One viewer passed out during the amputation scene and others sobbed, while Ralston said he cried the whole time that his character was stuck in the canyon.
