This is Hammer's first major horror/science-fiction hit, but almost as notable is the fact that its doomed astronaut is the founding member of the studio's tragic rogues' gallery of transformed innocents -- monsters that didn't ask for their fates.

The playing, as usual in films of this type, is serviceable rather than distinguished, with Brian Donlevy as a brusque and peremptory Quatermass and Jack Warner as the sturdily dependable representative of Scotland Yard.

A number of decent performances and a gritty realistic view of London makes this little sci-fi spin-off still worth a look.

A thoughtful, hard-hitting, and bizarrely touching landmark of the sci-fi genre, endlessly referenced and recycled in subsequent film and TV.

Nice little British sci-fi horror.

B-movie horror that cannot really be described as sci-fi with its awful portrayal of science as well as some terrible physics. Pretty poor alien invasion affair… More

Outdated but with an original storyline that is to be praised. The plot concept seems a bit too drawn out and has a predictable ending. Donlevy acts more like… More
