Did One Million Years B.C. use the same caveman language as When Dinosaurs Ruled the Earth? They both seemed to make heavy use of the word "akita," and I think it was used in similar ways. While the remake benefits from Raquel Welch and Ray Harryhausen, and lacks the rather cumbersome present-day introduction of the original, I wouldn't say it's a materially better movie. The story's about the same, with just as many arbitrary acts of nature interrupting to resolve things in lieu of actual plot points, and the effects just seem to be what I'd expect from the era, while the original's (while less sophisticated in the absolute) were fairly impressive for their era. Even though the effects are mostly stop-motion, another thing the movie shares with When Dinosaurs Ruled... is the incongruous inclusion of an iguana "dinosaur" in a couple of sequences. There's even a random giant tarantula at one point, like it accidentally wandered in from the set of a Jack Arnold film. But the Harryhausen sequences are pretty good. I daresay the fight between Tumak and the smallish theropod and the fight between the triceratops and the larger theropod count among Harryhausen's more iconic set pieces. Certainly the latter didn't have the outcome I would've expected.
