As a neophyte director, Wilder heavily relied on editor Doane Harrison for guidance. Harrison had edited "Hold Back the Dawn" (1941), which Brackett and Wilder had written. Unusually for an editor, Harrison was on the set for filming as well as working in the cutting room. Wilder later said, "I worked with a very good cutter, Doane Harrison, from whom I learned a great deal. He was much more of a help to me than the cameraman. When I became a director from a writer, my technical knowledge was very meagre." Harrison taught him how to "cut in the camera", a form of spontaneous editing that results in a minimal amount of film being shot and eliminates the possibility of studio heads later adding footage the director deemed unnecessary. In later years, Wilder commented, "When I finish a film, there is nothing on the cutting room floor but chewing gum wrappers and tears." Wilder's and Harrison's unusually close and important collaboration continued for every subsequent film directed by Wilder through "The Fortune Cookie" (1966).
