another movie I saw after a terrifying episode of the Outer Limits. that always made the following movie much scarier. I had no idea there would be several giant monsters in "The Angry Red Planet" upon first viewing, but it's one of my favorite Martian movies.
the monster is a puppet, which is far easier to discern with my older eyes than it was when I was 9 and watching it on a VHF station. I quite enjoyed the other effects, and the color change when they went out to Mars was cool. the first time I saw this Channel 2 didn't show the very end of the movie, the station just signed off. I had no idea how it ended for years, until home video came to my rescue.
