It has not yet been established which George Moon appeared in What's Yours?, a Tivoli Theatre revue staged in Sydney in October 1933. The cast also featured Mike Connors, Queenie Paul and Lulla Fanning (daughter of Maud Fanning).
A comparison of a photograph of George Moon (published in 1919) with stills from Pat Hanna's two films Diggers (1931) and Diggers in Blighty (1933) indicates that George Moon Snr played the character Joe Mulga, and not George Moon Jnr (see Green Room June 1919, p.12). It would appear in this case that a number of sources devoted to cinema, including the Internet Movie Database (IMDB), have inadvertently collapsed the film careers of father and son together, due both to the similarity in names and because they have not been aware of George Moon Senior's career as an internationally renowned vaudeville performer.
It is likely, too, that George Moon Snr also appeared in A Co-Respondent's Course (1931) and not his son, as the IMDB and other sources currently indicate. Although little is known of that film, it does have the distinction of being the first narrative film to have been released in Australia with sound.
NB: Richard Fotheringham indicates in his entry on Hanna's Diggers Company in the Companion to Theatre in Australia that George Moon took over the role of Joe Mulga from Joe Valli when Valli decided to develop a new character, Jock McTavish (p.191).
