In Someday This Pain Will Be Useful To You (Film Buff), based on the acclaimed Y/A novel by Peter Cameron, resourceful 17 year old James (Toby Regbo) begins by admitting that he "doesn't like to talk that much, hates politics, organized religion and all that" as he contemplates a New York City rooftop suicide. Below, in the apartment he shares with his sister Gillian (Deborah Ann Woll) and his unlucky in love, drama queen, gallery-owner mother Marjorie (Marcia Gay Harden), James does his best to be an obedient son.
