Buster Keaton joined M.G.M. and gave up creative control of his films and ultimately, his career! This is actually not a bad little film. This 1930 film is remembered more as the first film that finally allowed the viewing public to hear his voice, this behind the hollywood scenes comedy is an "interesting" viewing experience.
Note how this window card touts the soon to be dead Vaudeville. Replaced by the very types of films that this poster advertises!
