here's an interesting little movie, loosely based on Jules Verne's "Career of a Comet," which is full of stock footage from several movies, notably (and not surprisingly) "One Million, BC". I didn't see it until it aired on TNT in the early 90s, but I kind of like it. the actors are good and the stock footage is integrated as well as possible overall.
I was a bit surprised to Rodan make a cameo in this movie. it was very sudden, a sort of "what is that" and up pops Rodan. that sure wouldn't happen in this day and age. I wonder if it's the same people that released the feature "Rodan, the Flying Monster"? that would make more sense.
