Quatermass 2 (a.k.a. Enemy From Space in the United States and Canada) is a 1957 black-and-white British science fiction horror film drama from Hammer Film Productions, produced by Anthony Hinds, directed by Val Guest, that stars Brian Donlevy, and co-stars John Longden, Sidney James, Bryan Forbes, Vera Day, and William Franklyn. "Quatermass 2" is a sequel to Hammer's earlier film "The Quatermass Xperiment" (1955). It was originally shown in the UK as "Quatermass II". Like its predecessor, it is based on the BBC Television serial "Quatermass II" written by Nigel Kneale. Brian Donlevy reprises his role as the eponymous Professor Bernard Quatermass, making him the only actor to play the character twice in a film. It is considered as the first film sequel to use the ‘2’ / ‘II’ suffix within the title.
