Irma la Douce is a 1963 American romantic comedy film starring Jack Lemmon and Shirley MacLaine, directed by Billy Wilder. It is based on the 1956 French stage musical Irma La Douce by Marguerite Monnot and Alexandre Breffort. Irma la Douce was conceived as a Marilyn Monroe vehicle in 1962. The project would have reunited her with director Billy Wilder and actor Jack Lemmon, both of whom had worked with her on Some Like It Hot in 1959. After Monroe's death, the movie was recast with Shirley MacLaine, who had worked with Wilder and Lemmon on The Apartment (1960).
