Aside from a TV documentary about Howard Hawks, the first film ever directed by Peter Bogdanovich was possibly the worst science-fiction film ever made.
It was called Voyage to the Planet of Prehistoric Women, and it wasn’t even porn.
The film was actually about a projected manned mission to the planet Venus, which it depicts as a damper version of earth, populated by telepathic, telekinetic females. There is absolute nothing good about this film. Apparently Bogdanovich had not read a newspaper in a while, as the Venera 4 and Mariner 5 probes had explored Venus the previous year (this film was made in 1968) and revealed what the planet was actually like.
And Bogdanovich narrates as well. This is necessary because someone needs to explain what’s going on. Since the women are telepathic, all they had to do was exchange glances and have their thoughts dubbed in later. It was a black and white production, but somehow the ocean on Venus manages to look blue.
Then there is the refueling station in space halfway to Venus. How do they get the fuel to the station?
All the dialog is stilted and poorly delivered.
It has to be seen to be believed.
The only recognizable actor (?) in it was Mamie Van Doren.
Here is the storyline as described on IMDB:
“In 1998, six months after the collision of a meteor and subsequent explosion of a rocket sent to Venus, the team composed by the astronauts Kern and Sherman with the robot John is launched to explore Venus. They arrive in the Space Station Texas for refueling but they have problems while landing in Venus. Without communication, another rocket is launched with Commander Brendan Lockhart, Andre Ferneau and Hans Walter to rescue the first team and explore the planet. They use a vehicle to seek Kern and Sherman, but they are attacked by a flying reptile. They kill the animal without knowing that it is worshiped and considered the God Terah by Venusian women that use their powerful connection with nature to destroy the invaders. Meanwhile John helps the two cosmonauts to survive in the hostile land. ”
They don’t even mention the robot.
