IN this 1959 movie ,two main characters were male musicians so desperate to get a job, they disguise themselves as women and play with an all-girl band in gangster-dominated 1929 Chicago. Musicians Joe (Tony Curtis) and Jerry (Jack Lemmon) lose their jobs when a speakeasy owned by mob boss Spats Columbo (George Raft) is raided by prohibition agent Mulligan (Pat O’Brien).
Several weeks later, Joe and Jerry get a job performing in Urbana and end up witnessing a gangland massacre in a parking garage. Fearing that they will be next on the mobsters’ hit lists, Joe devises an ingenious plan for disguising their identities.
Soon they are all dolled up and performing as Josephine and Daphne in Sweet Sue’s all-girl orchestra. En route to Florida by train with Sweet Sue’s band, the boys (girls?) make the acquaintance of Sue’s lead singer Sugar Kane (Marilyn Monroe, in what may be her best performance). Joe and Jerry immediately fall in love, though of course their new feminine identities prevent them from acting on their desires
