As I write this on August 1st, 2022 the IMDb rating is 3.2 which is a bit of an injustice. It is a bit better than that, although not much. Maybe a '4' or a '5' if you compare it to similar movies from the 1950s and 1960s. This one takes advantage of the general interest in space exploration and came out a year before Armstrong and team landed on the Moon.
This is done in a strictly dramatic style but has mostly very irritating background music. I was able to watch it streaming on Amazon Prime. It was filmed mostly in Texas, including the Houston and Dallas areas. Curiously it even has a scene during a Baylor football game where a pretty homecoming queen was chosen.
Here's the premise, because of a problem with chromosomes the ratio of males to females on Mars has become about 100:1 so Mars needs females. (To stay morally correct the script makes a point of 'single' females.) So they have sent a small team in a classic saucer-shaped spaceship, they have handy powers, like being able to hypnotize Earthlings. They are NOT little and green, they look and speak like Earthlings and use all the same metrics of distance and time. Once they pilfer a set of clothing and change they fit right in.
As is common for movies of that time period much emphasis is placed on how 'pretty' the females need to be. I suppose that Baylor homecoming queen was a candidate because she was pretty. I'd like to say the movie ends on Mars, with pretty women having a slew of pretty little Martians but it doesn't end that way. The Martians pretty much fail in their mission but there is some interest and fun in watching them get there.
I was in my first year of graduate school when this came out, I didn't see it back then. But I am glad I came across it now, not a particularly good movie but a reasonably interesting one. And a good reminder of that era.
