Elle Fanning (Super 8) and Olly Alexander (Enter the Void) have signed on to star in God Help the Girl, a musical written and directed by Belle & Sebastian frontman Stuart Murdoch.  The band released a concept album titled God Help the Girl as a precursor to the film under the conceit of a “girl group” sound.  Eve, the main character sung by Catherine Ireton on the album, has yet to be cast.  According to Variety, Alexander will play “a cynical guitarist who accompanies Eve’s singing and becomes a mentor to Cass (Fanning), an American teen who tags alongside the duo as she learns to play the guitar.”  Producers Barry Mendel, Carole Sheridan, Chris Curling, and Phil Robertson raised more than $100,000 on Kickstarter to finance the movie.  HanWay Films will package the international rights to shop around at Cannes.  Murdoch will begin filming in Glasgow in June before Fanning moves on to shoot Disney’s Sleeping Beauty re-imagining Maleficent.
