"When it came to the tiger, I found that animating the movements of a large feline animal posed some difficulties, as it required precise and miniscule advancements in movement throughout its body. As well as tigers, I also studied domestic cats, and by so doing managed to achieve a combination of mannerisms represented by both. The overall impression is of latent ferocity and a lust for blood, but at the same time there are also slow, graceful movements that mask the creature's power."

“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.”
