The art of motion has always intrigued me. How a body - when it throws its weight from side to side and sits down - actually sits down. What muscles … - 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.

The task of instilling pathos into a creature that was, after all, an innocent victim of circumstances was something I had set myself from the outset, although I was restrained by the script... The Beast is a poor lost soul brought back to life by man and then destroyed by man. If it sounds familiar, it is. King Kong was a huge influence, as he would be in all the other creatures I would be father to.

I remember once, in my garage studio whilst I was animating a dinosaur, that things were not going right. Gradually they got worse and worse, as they do in situations where you don't keep your temper, and in a fit of accumulated rage I threw a hammer at the floor. Unfortunately, it bounced and went through a huge plate glass painting I had been preparing to use in a miniature set and which I had spent weeks carefully painting. I almost cried with frustration, and there and then decided that if I wanted to make this my career, I would have to control my temper. I am not saying that I didn't lose my temper after that incident - I did - but I always tried to remember that plate glass painting. It was a timely and necessary lesson.
