Duel is a 1971 American action-thriller television film directed by Steven Spielberg. It centers on a traveling salesman driving his car through rural California to meet a client. However, he finds himself chased and terrorized by the mostly unseen driver of a semi-truck. The screenplay by Richard Matheson adapts his own short story of the same name, published in the April 1971 issue of Playboy, and based on an encounter on November 22, 1963, when a trucker dangerously cut him off on a California freeway.

A television film, alternatively known as a television movie, made-for-TV film/movie, telefilm, telemovie or TV film/movie, is a feature-length film that is produced and originally distributed by or to a television network, in contrast to theatrical films made for initial showing in movie theaters, and direct-to-video films made for initial release on home video formats. In certain cases, such films may also be referred to and shown as a miniseries, which typically indicates a film that has been divided into multiple parts or a series that contains a predetermined, limited number of episodes.
