It! The Terror From Beyond Space Reviews

A good low-budget space thriller, the basic plot of which was re-used by Ridley Scott for his ALIEN (1979). Thompson, stranded on Mars, is the lone survivor of a space probe who is rescued by a ship commanded by Spalding. The latter suspects Thompson of having murdered his colleagues in order to ensure sufficient provender for his own survival, and takes off for Earth with Thompson a prisoner. The space shipmates are killed off one-by-one by alien stowaway "it," played by Corrigan in a rubber suit. They isolate the bloodsucking beast in a cargo compartment, but "it" claws its way through a bulkhead. The surviving crew members attempt to destroy the monster by every means at their disposal, using bullets, bombs, and bait, but all to no avail until Thompson, his tale verified, hits on the idea of having the survivors don space suits and then evacuating the air from the space ship. "It" obligingly suffocates. Back on Earth, the brave band is bemedalled.
