The Moon Is Blue

The Moon Is Blue is a 1953 American romantic comedy film produced and directed by Otto Preminger and starring William Holden, David Niven, and Maggie McNamara. Written by F. Hugh Herbert and based on his 1951 play of the same title, the film is about a young woman who meets an architect on the observation deck of the Empire State Building and quickly turns his life upside down.

Both men are determined to bed the young woman, but they quickly discover Patty is more interested in engaging in spirited discussions about the pressing moral and sexual issues of the day than surrendering her virginity to either one of them. After resisting their amorous advances throughout the night, Patty leaves and returns to the Empire State Building, where Donald finds her and proposes marriage.Otto Preminger had directed the 1951 Broadway production of F. Hugh Herberts play with Barbara Bel Geddes, Donald Cook, and Barry Nelson in the lead roles. Its successful run of 924 performances prompted him to contract with United Artists to finance and distribute a screen adaptation over which he would have complete control. He deferred his producers and directors salaries in exchange for 75 of the films profits. ........
