The film centres on a post-millennial 15-year-old (Kiernan Shipka) whose two obsessions are making movies and the real-life alternative rock band All Time Low.
She gets a chance to see the band live and film the concert for a class project, said The Hollywood Reporter.
Kara Hayward, the female lead in 'Moonrise Kingdom', features her as smart-mouthed best friend, with Ryan, 52, Scott Adsit ('30 Rock'), Bill Sage ('The Boy') and newcomer Joshua Boone rounding out the cast.
