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.
