The Quatermass Xperiment (1955) watch online

The Quatermass Xperiment (released as The Creeping Unknown in the United States) is a 1955 British science-fiction horror film from Hammer Film Productions, based on the 1953 BBC Television serial The Quatermass Experiment written by Nigel Kneale. The film was directed and co-written by Val Guest, produced by Anthony Hinds, and stars Brian Donlevy as the titular Professor Bernard Quatermass and Richard Wordsworth as the tormented astronaut Carroon. Jack Warner, David King-Wood, and Margia Dean appear in co-starring roles.

The film concerns three astronauts who have been launched into space aboard a single-stage-to-orbit rocket designed by Professor Quatermass. It crashlands with only one of its original crew, Victor Carroon (Wordsworth), still aboard. He begins mutating into an alien organism, which, if it spawns, will engulf the Earth and destroy humanity. After Carroon escapes from custody Quatermass and Inspector Lomax (Warner) of Scotland Yard have just hours to track him/it down and prevent a catastrophe.

Like its source TV serial, the film was a major success, especially in the UK. It also brought public attention to Hammer Film Productions around the world. A sequel, Quatermass 2, followed in 1957.
