Rupert Kathner (1904–1954) was an Australian film director best known for newsreels and low-budget films. He worked with Alma Brooks, an ex-barmaid, who co-produced, operated the camera, edited, co-scripted and acted in their films. Kathner and Brooks were also "shady con artists and fugitives from the law", sometimes described as the "Bonnie and Clyde" of the Australian film industry.
