Quatermass 2 is a 1957 black-and-white British science fiction horror film drama from Hammer Film Productions. It was originally released in the UK as Quatermass II and was produced by Anthony Hinds, directed by Val Guest, and stars Brian Donlevy with 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). 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.
