Which Marilyn Monroe comedy ends with the line, 'Nobody's perfect'?

The Marilyn Monroe comedy that ends with the line “Nobody’s perfect” is Some Like It Hot.

Billy Wilder’s 1959 comedy stars Monroe as Sugar Kane Kowalczyk, a singer who performs with an all-woman band. Tony Curtis and Jack Lemmon play musicians who disguise themselves as women after witnessing a gangland massacre. Their attempt to join Sugar’s touring group creates the film’s central chain of mistaken identities, romantic complications, and escalating farce.

The closing exchange occurs when Jerry, played by Lemmon, reveals to millionaire Osgood Fielding III that he is actually a man. Osgood refuses to let the revelation derail his marriage plans, replying that nobody is perfect. The line was reportedly written as a placeholder by Wilder and screenwriter I. A. L. Diamond, but it proved so effective that it remained in the finished film.

Some Like It Hot is often grouped with Monroe’s other celebrated comedies, including Gentlemen Prefer Blondes and How to Marry a Millionaire. It is also frequently remembered simply as a “Marilyn Monroe movie,” although Curtis and Lemmon drive much of the disguise plot. The film’s treatment of gender performance and Prohibition-era crime helped make it a comedy landmark beyond its star casting.
