Set in what was the future when this film was made and the inspiration for the screenwriter of Ridley Scott's Alien, It! is an interesting departure from the typical space alien films of the 1950s. On the surface of Mars the sole survivor of a disastrous mission is being rescued. The team of rescuers believe that he is responsible for killing his crew for their supplies, crazed by the belief that rescue may be distant or never coming. However he insists that the deaths were caused by an alien life form. Unknown to the crew they have an otherworldly hitchhiker.
