In 1948, Allen married Stephen Fleischman, who was working as a screenwriter in Hollywood. With Fleischman she moved to Europe and worked as a translator for two years. They moved to New York together in 1950 and Allen worked as a script clerk, even organizing a union, and was hired as an editor for commercials and industrial films at a company called Film Graphics. She began working with Carl Lerner, a screenwriter and editor who she had worked with her first summer at Columbia. Lerner recommended her to Robert Wise, where Allen edited her first important feature film, "Odds Against Tomorrow" (1959).
