Guys and Dolls is a 1955 American musical film starring Marlon Brando, Jean Simmons, Frank Sinatra, and Vivian Blaine. The picture was made by Samuel Goldwyn Productions and distributed by Metro-Goldwyn-Mayer (MGM). It was directed by Joseph L. Mankiewicz, who also wrote the screenplay. The film is based on the 1950 Broadway musical by composer and lyricist Frank Loesser, with a book by Jo Swerling and Abe Burrows, which, in turn, was loosely based on "The Idyll of Miss Sarah Brown" (1933) and "Blood Pressure", two short stories by Damon Runyon. Dances were choreographed by Michael Kidd, who had staged the dances for the Broadway production.

The film opened on November 3, 1955, at the Capitol Theatre in New York City to critical and commercial success. As of September 2024, a remake of the film, directed, co-produced and co-written by Rob Marshall, is currently in pre-production.
