Sundance London 2014 will play host to many independent movies, but perhaps none so eagerly anticipated and talked about as Leonard Abrahamson's Frank, inspired by the life of frontman and comic personality, Frank Sidebottom. Frank will get its UK premiere on the festival's opening night on April 25 following its first screening at Sundance in Utah back in January.

Michael Fassbender ('12 Years A Slave,' 'Shame') plays the titular masked musician and bandleader who wears a giant papier mache head throughout the film, which follows his band on their trip to playing the South by Southwest festival. Maggie Gyllenhaal and Domhnall Gleeson also star in the film as members of Frank's avant-garde pop band.

Written by Jon Ronson ('The Men Who Stare At Goats') and Peter Straughan ('Tinker Tailor Soldier Spy'), the film is based on the memoir by Jon Ronson and weaves a fictional tale loosely inspired by Frank Sidebottom, the stage persona of cult musician and comedian Chris Sievey, with influence from other outsider musicians like Daniel Johnston and Captain Beefheart, according to the film's website.

Frank will be released on the 2nd May in the UK.
