Despite the voyage to Venus is plagued by setbacks along the way, earth sends 2
landing probes to the planet to examine it, all supervised by Marsha Evans
(Faith Domergue) who stayed behind on the spaceship, & doctor Hartman
(Basil Rathbone) from the Lunar base.
But even at the landing one of the probes, containing Sherman (Yuri
Sarantsev) & Kern (Georgi Tejkh) plus superrobot John crashes & though
all passengers survive they are cut off communications.
The other probe meanwhile, containing youthful Andrej (Gennadi
Vernov), Hans (Georgi
Zhzhyonov) & commander Lockhart (Vladimir
Yemelyanov) lands safely, but the trio constantly attacked by
dinosaurs on their way to save Sherman & Kern, they even have to go
underwater to escape a flying reptile. But it is there where they find the
first signs of human life on Venus in form of a bronce idol, plus they seem to
constantly hear a woman singing, which especially fascinates Andrej.
In the end though, all seems lost for Sherman & Kern when a volcano
breaks out & they find themselves unprotected from the lava, but superrobot
John is able to carry them to safety, meaning to Lockhart, Hans & Andrej
(who have since emerged from the water again), & they hastily get back to
the probe to leave the planet again ... but not before Andrej finds the
definite proof for humans on venus in form of the small sculpture of a female
This is an example of how economic AIP operated in the mid-60's: They
had bought the (rather serious & special effects-laden) Russian
sci-fi-movie Planeta Bur/Planet of the Storms from 1962, but
instead of giving that movie a proper release (which - granted - might not have
been that easy in the Cold War times), some new scenes were added starring a
very tired Basil Rathbone & Faith Domergue, sort of tieing the spliced up
Russian footage together again, thus creating a special effects spectacle with
some stars attached to it for a comparably low budget. But as if that was not
enough, 3 years later they took massive footage from Planeta
more (not even shying away from taking the very same footage) to produce another
sci-fi spectacle, Voyage to the Planet of Prehistoric Women, now
starring Mamie Van Doren (!) in the new footage.
The results of such a mish-mash are expectedly uneven as Russian &
American footage don't go too well together & the American scenes always
seem to interrupt the Russian ones in the least fitting moments, but on a pure
trash level Voyage to the Prehistoric Planet is good-natured fun - which is of course not doing Planeta Bur itself much justice.
