aka Horrors of the Red Planet
How bad is it? It's cheap, dull and stagy.
Should you see it? You can skip it.
I fell asleep watching this more than once, so I can't give a description of the film as a whole, except that it follows "The Wizard of Oz" to such an extent that they even follow a golden road. Four astronauts on Mars have a series of adventures. The wizard is played by John Carradine, seen only in projection because his arthritis was so bad he couldn't move much at the time. Time must be unfrozen in order for the astronauts to return home.
