A space craft visiting a comet retrieves 3 people and after bringing them back to earth discover that they are space vampires who remove the lifeforce from people. This is a curious and intriguing Sci-Fi film. It has the feel of a film of two halves. The first half is space Sci-Fi and the second half is more save London from the zombies. What is unusual is that Mathilda May as the female space vampire is naked throughout the film. It is good, bad and bizarre all at the same time.
