Lenny Abrahamson's Frank has secured US distribution at the Sundance Film Festival.

The offbeat comedy made its world premiere to critical acclaim at this year's Sundance. Magnolia Pictures subsequently acquired North American rights to the film after intense distributor interest.

Director Abrahamson said: “I’m delighted that Frank has found a home in the US with Magnolia. I know that the team there has a genuine passion for Frank. Along with their skill and experience this makes them the right partners to bring the film to its audience there.”

Frank sees Abrahamson (What Richard Did, Garage, Adam & Paul) tell the story of a brilliant and eccentric musician (Michael Fassbender), who wears a giant fake head at all times.

The musical comedy also stars Maggie Gyllenhaal, Domhnall Gleeson and Scoot McNairy.

It is a fictional story loosely inspired by Frank Sidebottom, the persona of cult musician and comedian Chris Sievey, as well as other musicians such as Captain Beefheart and Daniel Johnson.

James Hickey, Chief Executive, Bord Scannán na hÉireann/the Irish Film Board said: “We are delighted that Frank has received such a positive international reaction after its World Premiere at Sundance.

"Lenny Abrahamson is one of Ireland’s leading directors and Frank showcases a host of Irish talent including Irish actors Domhnall Gleeson and Michael Fassbender. We hope this US sale will be the first of many international deals signed for this film.”

Frank will be released in Ireland in May.
