"Greek and Roman mythology had never been a favourite subject of mine at school, but as I grew older I began to appreciate the legends and realize that they contained a vivid world of adventure with wonderful heroes, villains and, most importantly, lots of fantastic creatures."

“The Ymir and Kong before him are both creatures wrenched from their natural environment against their will and finally killed by man. Although these creatures must always die, they should go out with a touch of pathos.”

“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.”

“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.”

“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.”

“Although Gwangi had been an allosaurus in Obie's version, I decided to make him more of a tyrannosaurus, and so I used elements from both species to make what I suppose could be called a 'tyrannosaurus al'. This combination allowed me a flexibility between aggressiveness and agility. If you like, he was glamourized.”

“The most popular exhibits in any natural history musem 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.”
