All the hot gamblers are in town, and they're all depending on Nathan Detroit to set up this week's incarnation of "The Oldest Established Permanent Floating Crap Game in New York"; the only problem is, he needs $1000 to get the place. Throw in Sarah Brown, who's short on sinners at the mission she runs; Sky Masterson, who accepts Nathan's $1000 bet that he can't get Sarah Brown to go with him to Havana; Miss Adelaide, who wants Nathan to marry her; Police Lieutenant Brannigan, who always seems to appear at the wrong time; and the music/lyrics of Frank Loesser, and you've got quite a musical. Includes the songs: Fugue for Tinhorns, "Luck Be a Lady", "Sit Down, You're Rocking the Boat".

After a tryout in Philadelphia, the play opened on Broadway on 24 November 1950 and closed on 28 November 1953 after 1200 performances. The play won a Tony for best musical and another for best choreography for Michael Kidd, who staged the dances and musical numbers in this movie. Original cast members included Robert Alda (father of Alan Alda) as Sky Masterson, Isabel Bigley as Sarah Brown, and Sam Levene as Nathan Detroit. Vivian Blaine as Adelaide, Stubby Kaye as Nicely-Nicely Johnson, B.S. Pully as Big Jule and Johnny Silver as Benny Southstreet all appeared in their original Broadway roles for the movie.

Nathan Detroit:
Everybody in the whole world who hates me is now here.

Continuity: Sky Masterson's handwriting on the back of the Bible verse card changes between shots.
