They Came from Beyond Space

"In this sci-fi drama, an alien spaceship breaks down and crashes on the moon. These creatures need help to make repairs and so use their powers to possess a few scientists and use them as slaves. Unfortunately for them, one scientist has a metal plate in his head and cannot be controlled. It is he who travels to the moon and has a little chat with the aliens and suggests they might get more help, if they simply asked for it. The story is based on Joseph Millard's book The Gods Hate Kansas."
