Storyline

One of several remaining members of its race, an alien from Venus is guided to Earth by disgruntled scientist Tom Anderson, who tells it which humans it should attach mind control devices to. Among them is his old friend, fellow scientist Paul Nelson. Nelson, after killing a flying bat-thing which carries the device, finally persuades the paranoid Anderson that he's been wrong to ally himself with an alien bent on world domination. They hurriedly leave when they discover Tom's wife has picked up a rifle and gone to the alien's cave to try to kill it. Written by Doug Sederberg <vornoff@sonic.net>

One of Roger Corman's most entertaining quickie monster movies.
8 June 2004 | by InfofreakSee all my reviews

A lot of people slam Roger Corman and try and act like every movie he made was worthless schlock, but while he definitely did make a few stinkers in his long career, the truth is that he was involved with more good than bad movies, either as a director or a producer. In fact, some of the movies he directed were better than just "good" e.g. 'The Trip' and 'Bloody Mama'. His early reputation mainly rests on his quickie monster movies, and 'It Conquered The World' is one of the most entertaining. So okay, it a low budget movie (and I mean LOW), it's very naive and the special effects are poor. The Venusian monster and the flying bat things will probably inspire fits of giggles in most people, but despite all that the movie has lots of energy and it hooks you straight in. It's also helped enormously by having an above average cast. The two leads are Peter Graves and Lee Van Cleef. Graves later became immortal on TV as Mr. Phelps in 'Mission: Impossible', and Van Cleef became a Western icon via his work in movies such as 'The Good, The Bad And The Ugly' and 'Death Rides A Horse'. Van Cleef gives an intense performance as a scientist obsessed with communication with aliens. Graves is his more level headed colleague. When Van Cleef intercepts messages from an extraterrestrial that only he can hear, his wife (Beverly Garland) and Graves think he is cracking up. He co-operates with the alien, helping it to try and take over the world. Garland is best known to most people for her later work on TV (e.g.'My Three Sons'), but boy is she sexy here! Hubba! Hubba! Being a Corman movie we shouldn't be surprised to see Dick Miller in the supporting cast. He plays a soldier, as does Jonathan Haze (Seymour in 'Little Shop Of Horrors) 'It Conquered The World' isn't up to the standards of such 1950s SF classics as 'The Incredible Shrinking Man' or 'Invasion Of The Body Snatchers', but it's lots of fun, and I recommend it to anyone who enjoys b-grade movies from this period.
