Clash was destined to be my last hero picture, and looking back, the decision to end my career at that point was absolutely right. With all the problems involved in production, and the knowledge that I was losing precious control of solo animation, I was forced to concede that it was time to stand aside for others and their new technology to take over.

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.

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