Bob Odenkirk and David Cross, creators and stars of the HBO comedy sketch series Mr. Show, bravely stretch one of that program's premises and characters into a generally successful, feature-length film in Run Ronnie Run! Cross plays Ronnie Dobbs, a trailer-park nitwit whose pranks find him routinely chased by small-town police. When an L.A. television producer (Odenkirk) discovers Ronnie is a favorite and frequent felon on a reality TV show, he signs Dobbs to his own series (Ronnie Dobbs Gets Arrested!) and re-settles him in Beverly Hills. Unprepared for fame, money, and power, Ronnie tries reinventing his life with mixed results. Much of Run Ronnie Run! is funny, though Cross--always a strong performer--is typically better than the material. The film works best as a showcase for sight gags and one-note sketches; among the latter is a great piece involving a self-help guru and a cameo by Jeff Goldblum. --Tom Keogh
