It! The Terror from Beyond Space

It! The Terror from Beyond Space is a black and white 1958 horror/sff film written by Jerome Bixby, who has some Star Trek credits. The narrator names the year as 1973, which was only 15 years in the future at that point. Ambitious of them to think we'd have manned missions to Mars by then. We haven't managed that yet, and sometimes I wonder if we ever will.

You get to see "It" fairly early. The actors here that I'm most familiar with are Dabbs Greer and Marshall Thompson.

This movie is said to have been the inspiration for the film Alien.

1000 Misspent Hours calls it "an extremely solid film". Moria says this film "really invented the concept that Alien turned into a subgenre – of aliens stalking crewmembers through spaceship corridors." ClassicSciFiMovies says it

holds its own as far as a story goes. The very spartan-ness of the set and costuming in It keep such accessories from getting in the way of the story.
