‘Every man its prisoner… every woman its slave!’
It Conquered the World is a 1956 sci-fi horror film about a well meaning scientist who guides an alien monster to Earth from Venus, so that he can rid mankind of feelings and emotions – but only death and sorrow results.
The movie was produced and directed by Roger Corman from a screenplay by Lou Rusoff and [uncredited] Charles B. Griffith (Creature from the Haunted Sea; The Little Shop of Horrors; The Undead; et al). The movie stars Peter Graves, Lee Van Cleef and Beverly Garland.
Plot:
Doctor Tom Anderson (Lee Van Cleef), an embittered scientist, has made contact with a Venusian creature while using his radio transmitter. The alien’s secret motivation is to take complete control of the Earth by enslaving humanity using mind control devices; the alien claims it only wants to bring peace to our troubled world by eliminating all emotions.
Anderson agrees to help the creature and even intends to allow it to assimilate his wife (Beverly Garland) and friend Dr Nelson (Peter Graves). The Venusian then disrupts all electric power on Earth, including motor vehicles, leaving Dr Nelson to resort to riding a bicycle.




Choice dialogue:
“Look I don’t know whether you can hear me but if you can, you listen good! I hate your living guts for what you’ve done to my husband and my world. I know you for the coward you are and I’m gonna kill you! Do you hear that? I’m gonna kill you!”
