Twilight Saga’s Ashley Greene will play Kristal’s daughter. The Big Bang Theory’s Johnny Galecki is playing band manager Terry Ork. Foo Fighters’ drummer Taylor Hawkins will play the original punk rocker Iggy Pop. And Harry Potter’s Rupert Grint will play Dead Boys guitarist Cheetah Chrome. The film begins shooting next month in Savannah, Ga., before moving to NYC. Bartha, who is appearing in NBC’s upcoming The New Normal, is repped by CAA and Management 360.
