One of the stranger movies at Sundance 2014 was Lenny Abrahamson's dark comedy "Frank" (Magnolia, August 15), which stars Domhnall Gleeson as a wannabe musician who joins an avant-garde pop band led by self-style musical genius Frank (Michael Fassbender), who hides himself inside a large fake head. Maggie Gyllenhaal and Scoot McNairy also star.
Fassbender is game to promote the movie, even if it wastes his good looks. Check out his performance of the film song "I Love You All" on The Colbert Report below. (The single is now available on iTunes.)
