It’s not easy to describe the work of Reggie Watts. But adjectives you frequently hear are “weird,” “brilliant” and “unpredictable.” The bandleader for The Late Late Show on CBS, Watts integrates stand-up comedy, improvisational beatbox and stream-of-consciousness monologue into his performances. Watts’ surreal schtick gets an ideal showcase in Benjamin Dickinson’s new film “Creative Control,” a satire of tech culture and invasive gadgetry.
