I swear I remember a sequel to this where a skeleton in a spacesuit with his helmet removed is decomposing in the woods next to a pile of mushrooms that are growing out of the skull's eyes, I thought it was so neat because it quietly told the story of a spaceman dying to mushroom spores so long ago that the scene takes on a peaceful quality as wind gently moves the foliage around the body regardless I love this one too, especially the confused monster biting on nothing after the spaceman vaporises himself
To seek out strange new life forms, spray stuff in its face, drug it, take samples of it, and obliterate it, when it tries to defend itself. I enjoyed this film and Death...in Space. Are you going to make more of these, maybe even a series?
