A genetic problem on Mars has decreased their female population so that there is only 1 female born to every 100 males. They believe that they can solve their problems by acquiring a few choice females from the Earth, for scientific study experimentation, and they're prepared to get the women whether they receive cooperation or not.
If properly fleshed out, the premise could have promise. But it's not fleshed out, and Mars Needs Women is loaded with problems. The plot as it stands makes very little logical sense. Not that this is a completely unwatchable film--it has many "so bad it's good" qualities, and my final score was a 6 out of 10.
Another problem is that the film seems extremely low budget. They barely even built any sets. Quite a few shots are just a couple of characters talking, framed tightly, against a solid-color backdrop. Most of the "fancier" shots, such as those of military aircraft flying and landing, are stock footage. The film is also full of padding--the stock footage goes on far longer than it should have. There is a scene that seems to go on forever where we just see a loudspeaker and listen to mostly unintelligible "military radio" banter. There is a striptease scene (apparently strippers are one of the prime candidates for the kind of women that Mars needs) that goes on for minutes and minutes with the stripper taking nothing off.
The Martians are just like humans for the most part, sparing the trouble of expensive make-up and sparing having to explain why Earth women would work for the task at hand. The Martian costumes are just shiny material with something like bathing caps on their heads and big headphone cups on their ears (this aspect is somewhat reminiscent of My Favorite Martian, and was even echoed in later material like Mork & Mindy, but in Mars Needs Women it doesn't have the intentional humor).
So why did I give this film a rating as high as 6 out of 10? Well, believe it or not, a few aspects of the film work as they were intended to. The whole sequence of the two Martians at the hotel, acquiring a press badge and so forth, was actually engaging and not really unintentionally funny. But most of the film is unintentionally funny, and most of it works on that level, too. You can laugh at the bad decisions made due to budget. You can laugh at the pacing. You can laugh at the hammy dialogue. You can laugh at how the Martians pick their women. And most of all, the more you spend time analyzing the ridiculous plot, the more you'll laugh.
