Last month, the troubled movie star Sean Penn’s new movie Flag Day had its premiere at Cannes, where it reportedly didn’t get booed. Penn directed Flag Day, and he stars in the small-scale crime drama alongside his daughter Dylan. It looks like Penn called in some serious favors for the soundtrack, which features Cat Power, Eddie Vedder, Glen Hansard, and the on-record debut of Olivia Vedder. (Don’t call her daughter.)
