You can watch this film all the way through, right here. It features Nikolai Otto as the Tramp character, but it's unclear whether he is supposed to be a clown playing Chaplin, or the actual Little Tramp character himself. He is quite impressive, appears in many scenes, and does not break character when 'backstage', helping the main characters dress and change. There are some great gags involving a cannon, and some good cane tricks. Truly fascinating!
