Like just about everyone else, I knew how this movie ended. It's based on the true story of Aron Ralston, a young adrenalin junkie who went canyoning in the wilds of Utah, solo - without telling a soul.
Spoiler alert: early on in the film Aron, played with incredible gravitas by James Franco, dislodges a boulder, plunging down a narrow crevice, and gets pinned by the same immovable rock. Directed by Danny Boyle (Shallow Grave, Trainspotting and Slumdog Millionaire), the film is based on Ralston's book Between a Rock and a Hard Place - and never was there an apter title.
