There are some films that are so horrible as to be fantastic. This is one of them. First Space Ship on Venus is one such film. Behind the iron curtain during the 60s anything science fiction was hot because the space race with America was in full swing.
According to wiki :
The film has been lampooned countless times. Again according to wiki :
The Ruins of Venus
The Venusians of this picture are down right nasty. This is an entire world of ruins, A.I. run plants, and god knows what other secrets are down there. Seriously this is one screwed up planet.
The whole place is an atomic wasteland filled with every type of wasteland horror you can think of. Vaults of still running machines, weapons plants still producing armaments for warriors who will never come. Nightmare mutant species of monster s slinking through the pollution choked landscape. And doomsday weapons waiting for some damned fool to activate them.
This means that there's a whole planet of horror just waiting for party of explorers to get back to its vaults. There could be anything on that planet from vast unexplored vaults to temples to god knows what. Recently a friend of mine was discussing this film with me. He stated that Its plot line was very similar to the recent Prometheus. Ancient astronauts, evidence found on Earth, still active weapons systems, a vast military engine that has outlived their creators. All the usual tropes are there.
