Quartet is a 1948 British anthology film with four segments, each based on a story by W. Somerset Maugham. The author appears at the start and end of the movie to introduce the stories and comment about his writing career. It was successful enough to produce two sequels, Trio (1950) and Encore (1951), and popularised the compendium film format, leading to films such as O. Henry's Full House in 1952. The screenplays for the stories were all written by R. C. Sherriff.
