Porgy and Bess is a 1959 American musical drama film directed by Otto Preminger, and starring Sidney Poitier and Dorothy Dandridge in the titular roles. It is based on the 1935 opera Porgy and Bess by George Gershwin, DuBose Heyward and Ira Gershwin, in turn based on Heyward's 1925 novel Porgy, as well as Heyward's subsequent 1927 non-musical stage adaptation, co-written with his wife Dorothy. The film's screenplay, which turned the operatic recitatives into spoken dialogue, was very closely based on the opera and was written by N. Richard Nash. In 2011, the film was chosen for inclusion in the National Film Registry of the Library of Congress.

Sidney Poitier was a Bahamian and American actor, film director, and diplomat. In 1964, he was the first Black actor and first Bahamian to win the Academy Award for Best Actor. He received two competitive Golden Globe Awards, a BAFTA Award, and a Grammy Award as well as nominations for two Emmy Awards and a Tony Award. In 1999, he was ranked among the "American Film Institute's 100 Stars". Poitier was one of the last surviving stars from the Golden Age of Hollywood cinema.
