The Professor is a 1919 American silentcomedy film made at the Chaplin Studios for the First National film company starring Charlie Chaplin. However, the film was never released or even completed. Chaplin abandoned production after finishing only one sequence: a single reel. Chaplin appears not as his usual Tramp character but as "Professor Bosco", a slovenly showman who brings his flea circus with him when staying at a flophouse. The fleas get loose during the night and create havoc.
