Otto Messmer and Pat Sullivan's Felix the Cat was the first widely popular cartoon character in film history. In this one, there's a gag involving gum and shoes at the beginning, and Felix transforms himself into the likeness of a handbag to travel to Hollywood, which is rather representative of the fantastic nature of the Felix cartoons. In Hollywood, Felix meets his peers, including Charlie Chaplin, who some say is the basis for much of Felix, and whom Messmer caricatured in another animation series. Felix also meets caricatures of Ben Turpin, William S. Hart, Douglas Fairbanks, Cecil B. DeMille and President of the Motion Picture Association of America, Will Hays, who others say was the basis for the next big cartoon star, Mickey Mouse. "Felix in Hollywood" is one of the earliest screen efforts at caricaturing live-action movie stars, something Looney Tunes later became famous for. Additionally, as Disney would similarly capitalize on later creations, the image of Felix was marketed extensively, appearing on merchandise and in newspaper comic strips.
