Film4 is a British digital television channel available in the United Kingdom, owned and operated by the Channel Four Television Corporation, that screens films. Film4 did not originally broadcast many blockbusters, but nowadays broadcasts many mainstream Hollywood films. The channel frequently has themed nights or seasons in which a number of films centred on one genre, director, actor or studio are shown. As Channel 4 also owns a film production company, Film4 Productions, it shows many of its in-house productions. Occasional non-film (but film-related) programmes are also shown.
