Last night I attended the New York premiere for “Brothers of the Head”, an IFC film that I’ve been meaning to catch since SXSW earlier this year. The film, which toggles between serious mockumentary and semi-experimental melange, concerns the story of two conjoined twins who become a successful punk rock act in 1970’s England. The highlight of the film is director Ken Russell, who appears as himself, dressed in imperial garb on the set of a film-within-the-film. It’s a cute ploy, and directors Keith Fulton and Louis Pepe (of the Terry Gilliam making-of “Lost in La Mancha”) make sure to wear their good taste in auteurs on their sleeves. But the picture, which only occasionally dazzles, doesn’t swim beyond the whole pastiche feeling of it all. We’ve seen this film in countless other films before: “Twin Falls Idaho” cut-up with “Velvet Goldmine” remixed to “Even Dwarves Started Small”. This would have been a fine debut; Anthony Dod Mantle’s photography captures the brothers’ melancholic inertia with a mercurial vogue, and my favorite scene, that of the two boys sharing an intimate shower, is practically grace incarnate . But Fulton and Pepe, self-professed fans of Wenders and the German noblesse, do just OK with their material, and you get the sense they haven’t paid their cinematic dues just yet.
