IT The Terror From Beyond SPACE

A rocket ship is sent to Mars to rescue the crew of an earlier ship that crashed there. Only the captain of the first ship survived long enough to be rescued. When he told his rescuers about how a monster had killed off the rest of his crew, they all assumed that he had murdered them in an effort to extend his own chances of survival, and were ordered by the authorities on Earth to bring him back to stand trial for the murder of his crew. Due to the carelessness of one of the crew on the rescue ship, an airlock was left open through which the creature entered the ship. When first one crewman, and then another disappear, the rest of the crew starts believing Ed's story, and they suddenly find themselves all in a battle for their very survival.
