This Hammer version of the 1953 television show features a hunt in London for the survivor of a rocket ship who is being transmuted from a human being into a monster capable of reproducing itself at such a rate that, in a short time, the whole nation could be destroyed.
The lone survivor, Victor Carroon (Richard Wordsworth), is met by his wife, Judith (Margia Dean) and the men who sent him on the scientific mission. While Victor is recognisable as the man who left the Earth a short while ago, there is a difference. It is this difference that strikes terror into all who behold him and sends his wife into the depths of despair.
Somewhere along his journey through space, he and his companions met with an unnameable experience that completely drained his companions of life and substance and injected him with a craving that transformed him into a thing to be shunned.
Some invisible force somehow got into the hermetically sealed rocket ship while it was in space and took possession of Victor’s body. It feeds on human blood and tissues of plant life too, transforming him into a monster – part animal, part plant.
London declares a state of emergency when the monster is discovered oozing around Westminster Abbey’s scaffolding.
The story is well put together, the people are credible, and the performances are excellent.
Released in the US as The Creeping Unknown.
