We don't set out to deliberately scare with our creatures, we try to make them as awe-inspiring as possible. - Ray Harryhausen

The most popular exhibits in any natural history museum are, without doubt, the dinosaurs. These creatures' popularity grows each year, partly because of the recent resurgence of dinosaur movies, but also because a skeleton of a full-sized tyrannosaurus rex still has the ability, even 65 million years after its death, to chill us to the bone.

I suppose we would be monsters to a Venusian. [...] We depicted the outer space creature as something strange rather than as a monster. He was from a strange place and therefore out of place in our familiar surroundings.

For some reason the creation was called a rhedosaurus, and although I can't remember where this name came from, I suspect Hal Chester or one of the writers coined it. Over the years, people have suggested that the first two letters relate to the initials of a certain animator. I have no comment.
