Mark Robson (4 December 1913 – 20 June 1978) was a Canadian-born film editor, film director and producer in Hollywood. Born in Montreal, Quebec, he moved to the United States at a young age. He studied at the University of California, Los Angeles then found work in the prop department at 20th Century Fox studios. He eventually went to work at RKO Pictures where he began training as a film editor. In 1940 he worked as an assistant to Robert Wise on the editing of Citizen Kane in addition to several other films. Both he and Wise benefited tremendously from producer and screenwriter Val Lewton, who promoted Robson from film editor to production assistant and later as director.
