Harold Lloyd released his 1929 comedy with some sound sequences, but this is the lesser-known silent version, produced simultaneously and recently restored by UCLA. The son of a famous San Francisco lawman, Lloyd is called back home by the police force to track down a Chinese drug lord called the Dragon, with a good deal of shtick devoted to fingerprints, then a novelty in crime detection. The movie isn't as funny as the previous year's Speedy, but Lloyd can still score with even the simplest gags, like climbing a flight of steps in the dark only to realize when the light comes on that he's perched at the top of a ladder. Writers Clyde Bruckman and Felix Adler endlessly recycled some of this film's physical bits in later years when they started writing for the Three Stooges. Bruckman and Malcolm St. Clair directed. 105 min.
