First Spaceship on Venus provides us with this critical piece of advice - if you go to another planet and find yourself closely pursued by black goo, don't shoot it - not unless you want something really bad to happen to Earth, at least. You have to admire the optimism of these filmmakers, though, as they -from their 1962 perspective - imagined that in 1985 the world would be a pretty happy place where people wore great big letters of the alphabet on their shirts for some insane reason, where a moon base would already have been established, and where scientists from all countries worked together to send a spaceship to Venus. Why Venus? A strange metallic object has been discovered; scientists have concluded it came from the famous Tunguska Event of 1908 and is nothing less than a spool containing a message from another planet - a planet which, given the trajectory of the object that exploded over Siberia all those years ago, had to be Venus. Lickety-split, it's up, up, and away to Venus, as Earth seeks its first contact with an alien race.
Things start to go a little downhill when the grouchy scientist from India interprets the mystery spool and learns it details a plan of attack on Earth by the Venusians. Of course, there's also the obligatory meteorite-dodging scene that has to play out. Undaunted, though, our international crew of a half dozen men and one woman (someone had to serve the nutritious liquid beverages, I guess) sporting exceedingly ridiculous spacesuits (leisure suits for space, I would call them, complemented by banana suits for takeoffs and landings) continue their mission to Venus. The landing mission doesn't go so well, either.
There's really no chemistry between the crewmembers, not even between the man and woman who supposedly had some kind of relationship in the past. The crew commander is interesting, though, because his hair seems to grow taller as the movie progresses and he also seems to experience some sort of German silent expressionist film flashbacks from time to time. Frankly, I didn't really care who made it back and who didn't, and Venus itself turned out to be less interesting than the interior of the boring ship (where chess games were the highlight of space life).
First Spaceship on Venus does at least attempt to be a serious science fiction movie, but at its heart it is yet another anti-nuclear film of the early 1960s. Frankly, I would not have tried to make a point at the end of the film because, all told, the whole thing was rather pointless to begin with.
