Question: Mo McCackie was a character in which 1934 Australian comedy musical film?
Context: Terry Scanlon (5 July 1913 – 21 August 1996) was an Australian comedian and pantomime artist.  He was one of Australia’s top comedians; he worked with some of the early greats of Australian comedy, including Roy Rene and George Wallace.  In the 1930s, however, he was one of the vanguard to modernise comedy out of baggy suits, funny face make up and slapstick into the more modern stand up style comedian - in a tailored suit, the only prop a cigarette in hand, delivering gags.  His role in the evolution of Australian comedy was acknowledged in a tribute by Joe Martin when he was honoured as a life member of the “ECHINDAS” by his peers years later.
