The Man from Planet X

Planet X is on a collision course with Earth, and Professor Elliott (Raymond Bond) is monitoring the action from his lonesome Scotland observatory. But when a spacecraft from the planet finally lands, the visitor inside falls into the clutches of Mears (William Schallert), an evil scientist. As the alien moves on to terrorize innocent Earthlings and turn them into zombies, a plucky reporter (Robert Clarke) tries to get the real scoop.
