March-May 1956 - Marilyn Monroe Productions began filming Bus Stop in March 1956. Although excited, Milton and Marilyn were also apprehensive heading into the project. Having won their battle with the studio and negotiated new terms, everything was riding on their first film together. Marilyn had one job: focusing on delivering the best performance of her life. Milton concentrated on all the other details, particularly aesthetics and how his collaborator was captured on film.
