Based on a true story, this drama by British director Danny Boyle (Slumdog Millionaire) features a terrific performance from James Franco as a cocksure rock climber who gets pinned by a boulder during a solo excursion in a Utah canyon. Boyle loads up on visual gimmickry to indicate the passage of time, the depletion of the hero’s resources, and what’s running through his head. But aside from an exhilarating opening and a gruesome climax, the movie isn’t all that rich emotionally; all the visual razzle-dazzle winds up serving a pat lesson about people needing other people.
