Alien 2 On Earth

Alien 2 On Earth is a horror and science fiction film released in 1980. A team of cave explorers goes into an underground cavern and finds a strange living rock that holds flesh-eating creatures set on wiping out humanity. Belinda Mayne's nude scene as Thelma Joyce is the best known part of the film. It was made on a tiny budget as an unofficial follow-up to the 1979 film Alien, though the two stories barely connect.
