Horrors of the Red Planet, AKA Wizard of Mars is a good "B" late night movie.
Typical old 60's Sci Fi movie with good plot, OK special effects "for the era", cheesey acting, bad actors no one ever heard of, etc, etc,
Astronauts in space flight near Mars are forced to make an emergency landing near the polar icecap of Mars after their ship is damaged by a Magnetic Storm.
They spend the next few days on a quest for the "Main Stage" apparently part of their ship jettisoned before the crash, to obtain supplies, oxygen etc. and stay alive till a rescue ship arrives.
They journey through a large series of caverns on their way south towards the Main Stage, actually this sequence was filmed in Carlsbad Caverns I believe.
They are threated by limited Oxygen, weird floating plant creatures, Hot Lava and lightning storms along the way.
As they finally reach what they think is their Main Stage that they have been tracking via it's radio beacon signal, they realize that it is just a wreck of an old space probe.
They discover it has some Oxygen left in the tanks, which saves the day, at least for the tme being.
You have to ask why would an unmanned probe be carring Oxygen anyway?
In the morning when the lightning storm clears they find the ruins of an ancient Martian city and set off to explore it.
They find the remains of Martians inside and end up conversing with an aparitian of the Martians collective spirit or whatever who explains the Martians history, the ruins of the city, etc, etc,
Our fearless band of astronauts end up helping the Martian spirit by starting up an ancient time machine of sorts, and are then transported back in time to before the Magnetic Storm that originally stranded them on Mars.
All in all a decent late night "B" movie.
My only complaint is the transfer to DVD is pretty bad.
I have this movie on VHS and the picture quality of the DVD is about the same.
