Valley of the Dragons

I grew up in a tiny little town that had nothing going on except a run down movie theater. I recall somebody taking me to see this movie when I was a little kid. I'm guessing that Valley hit our screen around 63 or 64, a good two years after its release. Anyhow, I loved every second of it and still have vivid memories of the movie to this day. (I caught it one or two other times on TV during the seventies) It had a very dramatic opening scene: two duelist were suddenly swept away just before they were about to kill each other. Then they find themselves on a strange world filled with huge dinosaurs doing battle with each other. As if that wasn't enough they soon are under attack by savage primates. I'm guessing it sorta goes downhill after that but this film was a major event in my very ordinary little life back in the early sixties. I will always be grateful for that no matter how this holds up in comparison to today's stuff. It was pure cinema magic back then.
