The Seven Year Itch is a 1955 American romantic comedy film based on a three-act play with the same name by George Axelrod. The film was co-written and directed by Billy Wilder, and stars Marilyn Monroe and Tom Ewell, reprising his Broadway role from the play. It contains one of the most iconic images of the 20th century – Monroe standing on a subway grate as her white dress is blown by a passing train. The titular phrase, which refers to declining interest in a monogamous relationship after seven years of marriage, has been used by psychologists.
When his family goes away for the summer, a so far faithful husband is tempted by a beautiful neighbor (Marilyn Monroe).
