In his physical presentation as well as his performance style, George Wallace differed from international stars of slapstick comedy. For instance, his clothing and speech allude to an Australian working-class type and contrast with Charles Chaplin's mock-dapper Tramp persona. The fact that Wallace's performances combine tap-dancing with pratfalls makes him unusual among film comedians anywhere. Moreover, Wallace's films prefigure developments in Hollywood comedy. An example is the fictional country of Betonia in "His Royal Highness", which predates satirical depictions of fictional nations in such celebrated films as The Marx Brothers' "Duck Soup" (1933) and Charles Chaplin's "The Great Dictator" (1940). Other aspects of Wallace's films that are relatively unusual for the period are the comedic treatment of haunted houses in "Harmony Row" and "Gone to the Dogs" and scientific experimentation in "Gone to the Dogs", which emphasize the resourcefulness of Australian filmmaking in the face of Hollywood's international dominance.
