It! The Terror from Beyond Space - (Black and White / Sci Fi )- 1958

"A rescue space ship travels out to Mars to retrieve the only survivor of a space probe that has experienced a disaster,
That one survivor, Col. Carruthers, is accused of murdering his fellow crewmen. But Carruthers claims that the killer is a Martian monster.
Which is now at large on the rescue ship."

This 1958 Black-and-White Sci-Fi film, has long been considered to be an “influence” for director Ridley Scott’s 1979 film ‘ALIEN.’
