The film, which premiered Saturday at the Sundance Film Festival, is a sensitive, complicated and provocative story about a prominent gay activist who, in just a few years, denounces his homosexuality. Justin Kelly's film opens with a buttoned-up Michael telling a terrified young man that homosexuality is immoral, before abruptly jumping back in time to show Michael in his activist days (and, in fact, at a raucous rave, where Franco says he was almost blinded by green glitter). The two have an easy, intimate and wholly lived-in chemistry when portraying Michael and Bennett as a happy couple. [...] the actors, who look so comfortable together on screen weren't even acquaintances in real life prior to the film.
