An oddly enjoyable comedy full of violence & nasty behavior

Charlie the Tramp comes to a kid auto race, which a director just happens to be filming. Charlie constantly gets in the way, annoying the director, cameraman, and public. This film marks the first appearance of Charlie Chaplin's famous Tramp character.

Charlie plays two roles as two spectators at a music-hall show. It has a few good laughs and also provides an interesting look at old-fashioned theater entertainment.
