Also starring (but not pictured) are Scoot McNairy (Argo, Killing Me Softly) and musician Carla Azar (most recently drummer on Jack White’s Blunderbuss) and French actor/musician Francois Civil.

Frank is a comedy about a young wannabe musician, Jon (Gleeson), who discovers he’s bitten off more than he can chew when he joins a band of eccentric pop musicians led by the mysterious and enigmatic Frank (Fassbender) and his terrifying sidekick Clara (Gyllenhaal).

The film is directed by Ireland’s critically acclaimed Lenny Abrahamson (Adam & Paul, Garage, What Richard Did).  Frank is written by Jon Ronson (The Men Who Stare At Goats) and Peter Straughan  (Tinker Tailor Soldier Spy, The Men Who Stare At Goats). Frank is based on the memoir by Jon Ronson and is a fictional story loosely inspired by Frank Sidebottom, the persona of cult musician and comedy legend Chris Sievey, as well as outsider musicians like Daniel Johnston and Captain Beefheart. The director of photography is James Mather (Adam & Paul), production designer Richard Bullock (StreetDance 3D, Spike Island). Music is by regular Abrahamson collaborator, Stephen Rennicks.

Frank is an Element Pictures and Runaway Fridge production. Ed Guiney (What Richard Did, The Guard) produces for Element Pictures with David Barron (Harry Potter and the Deathly Hollows: part 1 and part  2, Jack Ryan) and Stevie Lee (The Making of a Lady) producing for Runaway Fridge. Executive producers are Tessa Ross, Katherine Butler and Andrew Lowe.

The film was developed by Film4 and is being financed by Film4, the BFI, The Irish Film Board as well as tax breaks in New Mexico and Ireland. Protagonist Pictures are handling international sales and Artificial Eye will distribute in the UK.
