Based on the best selling novel by Peter Cameron, 'Someday This Pain Will Be Useful To You' is a funny and heartfelt film about a vulnerable yet precocious teenager named James (played by extraordinary newcomer, Toby Regbo) with a deep appreciation for the world and no idea how to live in it. Living in New York City, the child of divorced parents (Marcia Gay Harden and Peter Gallagher) who may be better served examining their own lives, James rejects all the assumptions that govern the adult world around him, including the expectation that he will go college in the Fall.
