The other two, "Let George Do It" (1938) and "Gone to the Dogs" (1939), were directed by Ken G. Hall for Cinesound Productions. Wallace's contributions to these films extended beyond his performances. He developed the concepts for "His Royal Highness", "Harmony Row" and "A Ticket in Tatts" by drawing on his stage revues, and co-wrote "Let George Do It" and "Gone to the Dogs". Wallace's other film work included a 1932 short film, "Oh! What a Night!", which he is said to have directed unofficially. In later years, he was seen in supporting roles in two dramatic films, "The Rats of Tobruk" (Charles Chauvel, 1944, Australia) and "Wherever She Goes" (Michael Gordon, 1953, USA/Australia).
