The film makes a home in your brain and the only cure is to see it again.

While it doesn't offer any answers, it both thrills and makes you think.

I enjoyed watching this film and would recommend other to give it a try , (as I am) but this movie, although enjoyable to watch due to the better than average acting fails to add anything new to its storyline that is all too familiar to these types of movies.

It is a whirlwind of delight --- attractive actors, stunning couture, spectacular sets and outrageous parties. It's a feast for the eyes. But what really makes this dramedy work is the acting.

I don't know what the heck I just watched.This movie is terrible from beginning to end. Apparently the planet of prehistoric women is Venus and the prehistoric women are mermaids who use telepathy to communicate.Sounds pretty advanced to me. When the astronauts first see Venus they say they can tell it's prehistoric. How can they tell people on the planet haven't started to record history if they haven't been there? At one point a guy even has to take his helmet off and has no trouble breathing.This is one of those movies I could pick apart line by line but I won't waste anyone's time. Never watch this movie,trust me.

Pretty good science fiction film takes a trip to Venus where rubber dinosaur like creatures just a little taller than men roam free, and a blood sucking plant with strong stems that grab the astronauts and attempt to suck them in. A giant pre- historic like bird turns out to be the deity for pre-historic women who are unable to speak but can read each other's minds. When it is killed, the mute women (lead by Mamie Van Doren) bow revenge. Told in narration through flashback by one of the astronauts, it has a very eerie soundtrack and at times is extremely quiet. It is only moderately silly, most obvious when the women pick up the rubber head of the bird. The planet highly resembles the earth, with only a few signs that this is a different world. Scenes in outer space almost seem animated. This ranks as a cult film that manages not to be campy, and that makes it several notches above those films that seemed to go out of their way to appear unintentionally funny.

Director Peter Bogdanovich had to start somewhere; following second unit work on Roger Corman's "The Wild Angels," Corman allowed the hardworking novice an opportunity to do a feature film utilizing the exact same Russian stock footage used by Curtis Harrington for his 1965 "Voyage to the Prehistoric Planet," a 1962 entry titled "Planeta bur" (Planet of Storms). It's no stretch to assume that the first-time director just didn't have his heart in his work, as all of his newly shot footage features a dozen bikini-clad models not required to speak, everything narrated by Bogdanovich himself. There is no integration between the alien mermaids and the Russian characters, so the whole thing just sits there, aimlessly meandering from one crisis to another. Granted, I had just viewed Curtis Harrington's work on his "Voyage," so all the Soviet footage was already familiar to me, but at least Harrington had Basil Rathbone and Faith Domergue actually communicating with the Russian astronauts, their scenes already dubbed into English. The blame here simply lies with Roger Corman, who felt the need for another retread rather than something truly original. "Voyage to the Planet of Prehistoric Women" carries a 1967 copyright, and at least Corman was satisfied enough to grant Bogdanovich the freedom to do a feature starring Boris Karloff, who supposedly owed Roger two days work on a previous contract; we can all be grateful that the result was the superlative "Targets," shot in Dec 1967, an achievement that even "The Last Picture Show" couldn't top (some may feel free to disagree). Pittsburgh's Chiller Theater aired "Prehistoric Planet" only 3 times, "Prehistoric Women" 4 times (maybe it was the bikinis), all from July 1969 to July 1972.

*Spoiler/plot- 1968 Voyages to the Planet of Prehistoric Women, A group of astronauts attempt a rescue mission on Venus. The stranded landing party is attacked by various perils as prehistoric monsters large and small. Their misadventures are watched from afar by a group of telepathic Venusian alien women. They worship the Venusian pterodactyl 'god' named, 'Tera'. Essentially a bad copy of the 1965 original Venus exploration film. *Special stars- Blonde bombshell Mamie Van Doren and her blond female bikinied Venusian sisters in heavy eye make-up is something to experience but take very lightly. Peter Bogdanovich directs schlock again. *Theme- Planet's can have civilizations, just keep looking. Maybe they are blond and gorgeous. *Based on- 1965, Voyages to the Prehistoric Planet & Russian film, 'Planet of Storms '62 *Trivia/location/goofs- With a Peter Bogdanovich vague narrative installed, you can make another B-movie just add bikinis. The beach and shore ocean scenes with the alien females do not match the other stock footage due to wrong color correction and heavy film scatches. *Emotion- A big bikinied bore...Roger Corman produces and Peter Bogdanovich directs another film of the same exact remake, again with a new cast!
