Omnibus film

An anthology film (also known as an omnibus film, package film, or portmanteau film) is a subgenre of films consisting of several different short films, often tied together by only a single theme, premise, or brief interlocking event (often a turning point). Sometimes each one is directed by a different director. These differ from "revue films" such as Paramount on Parade (1930)—which were common in Hollywood in the early sound film era to show off their stars and related vaudeville-style acts—composite films, and compilation films.

Sometimes there is a theme, such as a place (e.g. New York Stories, Paris, je t'aime), a person (e.g. Four Rooms), or a thing (e.g. Twenty Bucks, Coffee and Cigarettes), that is present in each story and serves to bind them together. Two of the earliest films to use the form were Edmund Goulding's Grand Hotel (1932), released by MGM with an all-star cast; and Paramount's If I Had a Million (also 1932), featuring segments helmed by a number of directors.

European directors such as Roberto Rossellini directed anthology films such as L'Amore (segments: "Il Miracolo" and "Una voce umana") (1948), Les Sept péchés capitaux (segment: "Envie, L'Envy") (1952), Siamo donne (segment: "Ingrid Bergman") (1953), and Amori di mezzo secolo (segment: "Napoli 1943") (1954). American studios soon followed with films like Quartet (1948) based on stories by W. Somerset Maugham. This led to two sequels, Trio (1950) and Encore (1951), as well as imitators like O. Henry's Full House (1952) and Actor's and Sin (1952).
