Get On Up, film review: Here is a biopic that avoids the cliches Tate Taylor's tremendously energetic film about James Brown, the "Godfather of Soul," was produced by Mick Jagger's company. It comes at its subject in inventive and oblique fashion. The screenplay, written by Jez Butterworth and his brother John-Henry Butterworth, starts with Brown toward the end of his career, throwing a tantrum because a stranger has used his bathroom. Cue guns, a siege and a police chase. From this abrasive beginning, the film leaps back and forth in time. We see Brown as an impoverished kid in the backwoods of South Carolina in the 1930s; as a delinquent teenager fresh out of prison and discovering gospel music; as the singer of the Famous Flames; and as the bouffanted, cape-wearing superstar he became. Like its subject, the film never stays still. There are shots of Brown talking directly to camera and of him answering questions at press conferences. Chadwick Boseman gives a bravura performance as Brown. He has such energy and charisma that his character's obnoxiousness and increasingly erratic behaviour never become an issue. The film shows him beating up his wife, terrorising the poor woman who had the temerity to use his bathroom, betraying his best friend and treating his long-suffering band with contempt. Even so, we can't help but root for him. "You special, boy, you got the spirit in you," he is told early on. The film makes it clear that he suffered from racism and extreme poverty, but doesn't try to use that as an excuse or explanation for his own later excesses. One of the most refreshing aspects of Get on Up is that Brown never apologises and isn't prey to introspection. Instead, "the hardest working man in show business" (as he was nicknamed) channelled his energy into his music. The film tapers off in its final reel, ending on a conventional note - but not before it has done its best to capture its subject in all his manic and absurd glory.
