The Quatermass Xperiment (a.k.a. The Creeping Unknown in the United States) is a 1955 British science fiction horror film drama from Hammer Film Productions, based on the 1953 BBC Television serial The Quatermass Experiment written by Nigel Kneale. The film was produced by Anthony Hinds, directed by Val Guest, and stars Brian Donlevy as the eponymous Professor Bernard Quatermass and Richard Wordsworth as the tormented Carroon. Jack Warner, David King-Wood, and Margia Dean appear in co-starring roles.
The film's storyline concerns three astronauts that have been launched into space aboard a single stage to orbit rocket. The returning spacecraft, designed by Professor Quatermass, crash lands with only one of its original crew aboard, Victor Carroon (Richard Wordsworth). Something has infected him during the spaceflight, and he begins mutating into an alien organism which, if it spawns, will engulf the Earth and destroy humanity. When the mutating Carroon escapes from custody, Quatermass and Scotland Yard's Inspector Lomax (Jack Warner), have just hours to track it down and prevent a catastrophe.
Like its source TV serial, the film was a major success in the UK and brought public attention to Hammer Film Productions' name around the world. The film's US release was as a double feature with The Black Sleep.
