Mutiny in Outer Space

Mutiny in Outer Space is a 1965 black-and-white independent American science fiction film, written, produced, and directed by Hugo Grimaldi and Arthur C. Pierce, although Pierce was not credited as directing. It stars William Leslie, Dolores Faith, Pamela Curran, and Richard Garland.

Space Station X-7 is overrun by a previously unknown but deadly alien fungus that originated in ice caves on the Moon and was inadvertently brought back by astronauts returning with lunar samples. In order to save the space station from destruction, members of the crew are forced to mutiny against X-7's commander, who is not in his right mind because of "space raptures".

In the US, Mutiny in Outer Space was theatrically released as the second film of a double feature with The Human Duplicators.
