Kate Mara Joining Danny Boyle’s 127 Hours

ON

Kate Mara is negotiating to join James Franco and Amber Tamblyn in Danny Boyle’s 127 Hours at Fox Searchlight Pictures.

The film tells the story of mountaineer Aron Ralston, whose right forearm got pinned for nearly five days under a boulder during a climb in Utah in May 2003. He used a dull knife to amputate the limb, then scaled a 65-foot sheer wall and hiked out before running into a family that gave him water and food.

Mara and Tamblyn play hikers he meets before his ordeal.

Mara can next be seen in theaters in Iron Man 2 playing a federal investigator.
