"Operation Ganymed" is sci-fi for thinkers, those with imagination, and those who enjoy looking beyond the obvious. Returning Russian and American crew finds their hook up for re-entry strangely absent. After four years in space they seem to have been forgotten. After landing somewhere in Mexico, they must try and survive on Earth. Their challenge is not an easy one. Everything appears as desolate and deserted as the planet Jupiter which they have just returned from. Gradually, individual dynamics and desperation, overcomes discipline. Flashbacks in the form of hallucinations unfolds a tragic story of exploration, and a savage hopelessness prevails. Despite marginal special effects, the story is excellent. - MERK

I agree that the special effects in this movie are really sub-standard compared to what was possible in 1977 (it was a low-budget movie), but the story itself is interesting and pretty clear and there is never a doubt that the 5 (and not "about 4" - did you really watch this movie???) survivors make it back to earth and are stranded in Mexico (more precise: at the deserted Baja California coast). The water is a problem for these survivors because they carry a small portable filter with which they can produce drinkable water from salt water (that's why they stay at the coast at the beginning) but not enough for all of them. What makes this movie interesting imho is the fact that they managed to survive the tough two years return voyage only by strict self-discipline whilst being in the small space capsule, but as soon after they have reached the earth orbit, all the suppressed group dynamics and character differences are starting to show and lead to the group's breakup. Don, the scientist, who is the physically and mentally weakest of those who survived, is, on the other hand, the most flexible of all and he is the only one who can adapt to their new situation.

Although this t.v. movie was made around the same time as Star Wars, it has nothing of a space opera. Rainer Erler is more interested in the inner space of his characters. Five astronauts return to earth after more than four years on a catastrophically failed mission to Ganymede during which 21 of their team perished. When no one answers their calls, they perform an emergency landing in the ocean and finally get to a rocky desert coast that looks much like a strange planet. While they did find some evidence of life on Ganymede, they have a hard time doing so on Earth, until they surmise that the human race must have destroyed itself in a nuclear war. Their despair over the apparent utter futility of all that they have endured leads them to madness, murder and cannibalism.Some of the effects shots betray the movie's low budget (in terms of money as well as time, it seems), e.g. when in a supposedly zero gravity scene you can see that one of the characters is actually hanging from the ceiling in his seat because his hair is standing up straight. Other scenes seem to have been shot in a real zero gravity environment.Apart from looking cheap in some and dated in all places, this movie has many defects, not the least of which is the utterly unsuitable score. I still give it a high mark because it succeeds in creating an apocalyptic atmosphere and depicting people's emotional reactions to it better than many other movies I have seen.An intriguing presence in the movie is a beautiful girl that keeps appearing to one of the characters in his daydreams or hallucinations. She is played by Vicky Roskilly, an actress who seems to have made this one movie only and then disappeared from the face of the earth, at least as far as any traces of her on the internet are concerned. I hope she is alive and well.

The storyline is 3 ships travel to Ganymede (moon of Jupiter); about 18 people go, about 4 come back. Don is mentally unstable since he was felt responsible for the deaths of 2 crew members that went to collect samples of organic compounds for him (proving life was on Ganymede). About 1/3 of the movie is in space returning to Earth, 1/3 flash back to Ganymede, and 1/3 hiking through the desert when they force on a landing on (what may/may-not be) Earth after they aren't met when they return to Earth's orbit. The dubbing was one of those classic "ha! you are a crazy person, yes a crazy person, and I say that without malice, I do, it's just that you are a crazy person." who's responsible for that dubbing? Some of the on-Ganymede effects were well done, but in general it seemed like the cinematography was done as a high-school drama project. 10 minutes spent with the camera trained on someone rapelling down some rocks. At the end, you really don't have a clue what it was all about. Was Don crazy? Were they on Earth? Did Earth still exist? Were they in Mexico? Did 14 really die on Ganymede? Why did no one meet them on their return? And considering they were out of water all the time, how did they keep getting more?
