I hate to admit it, but I've actually seen that film on TV a couple of times - and Geez! - talk about an inauspicious debut!
I remember seeing
One Million Years BC in the local movie theatre back in the day. I used to make amateur stop motion 8mm movies and was a big Ray Harryhausen fan. But, after seeing Raquel Welch, I confess that those rubber dinosaurs definitely took a back seat!
Damn, I'm feeling old!
