The film is a remake by Wilder and I. A. L. Diamond of a 1935 French movie, Fanfare d'Amour, from the story by Robert Thoeren and Michael Logan, which was also remade in 1951 by German director Kurt Hoffmann as Fanfaren der Liebe. However, both the French and German films were without the gangsters that are an integral part of the plot of Some Like It Hot. Wilder's working title for his film was Fanfares of Love, then Not Tonight, Josephine before he decided on Some Like It Hot as its release title.
During 1981, after the worldwide success of the French comedy La Cage aux Folles, United Artists re-released Some Like It Hot to theatres. In 2000, the American Film Institute listed Some Like It Hot as the greatest American comedy film of all time.
PlotTwo struggling musicians, Joe and Jerry (Tony Curtis and Jack Lemmon), witness the Saint Valentine's Day massacre of 1929. When the Chicago gangsters, led by "Spats" Colombo (George Raft), see them, the two flee for their lives. They escape and decide to leave town, taking a job that requires them to disguise themselves as women, playing in an all-girl musical band headed to Florida. Calling themselves Josephine and Daphne, they join the band and board a train. Joe and Jerry both become enamored of "Sugar Kane" (Marilyn Monroe), the band's vocalist and ukulele player, and struggle for her affection while maintaining their disguises. In Florida, Joe woos Sugar by assuming a second disguise as a millionaire named "Junior", the heir to Shell Oil, while mimicking Cary Grant's voice. An actual millionaire, Osgood Fielding III (Joe E. Brown), becomes enamored of Jerry in his Daphne guise. One night Osgood asks Daphne out to his yacht. Joe convinces Daphne to keep Osgood ashore while he goes on the yacht with Sugar. That night Osgood proposes to Daphne who, in a state of excitement, accepts, believing he can receive a large settlement from Osgood immediately following their wedding ceremony.
When the mobsters arrive at the same hotel for a conference honoring "Friends of Italian Opera", Spats and his gang see Joe and Jerry. After several humorous chases (and witnessing yet another mob murder, this time of Spats himself and his crew), Jerry, Joe, Sugar, and Osgood escape to the millionaire's yacht. En route, Joe reveals to Sugar his true identity and Sugar tells Joe that she's in love with him regardless. Joe tells her that he is not good enough for her, that she would be getting the "fuzzy end of the lollipop" yet again, but Sugar loves him anyway. Jerry, for his part, tries to explain to Osgood that he cannot marry him, launching into a range of objections from insisting that he can't get married in his mother's dress ("We are not built the same way") to the tearful confession that he can "never have children." Osgood dismisses them all and remains determined to go through with the marriage. Finally, exasperated, Jerry removes his wig and shouts, "I'm a man!", only for Osgood to override this final revelation by uttering the film's memorable last line: "Well, nobody's perfect."
