It's an interesting idea, though. Over the years, I've used computers to mix audio, edit video, generate 3D artwork, virtually tour distant buildings, make friends, make enemies, make a living, retouch photos, screen video, lay out documents, design typefaces, kill monsters, buy books and CDs, and read Doonesbury. To me, the computer is defined as something that changes all the time. It will do exactly what you need it to do. It will do this in exactly the way you need it to be done.
Creatures are, of course, easier to do than people.
Given enough time, money and talent, you can accomplish anything. Now, we just talk about how much it will cost. When they storyboarded Werewolf , we looked at that fountain scene and then at each other, and laughed, because we had no idea how we'd do it, but six months later, we'd done it. For other shots, it works damn well, maybe better than animatronics, unless you're Rick Baker. There's a transformation sequence, where the female lead is turning into a werewolf.
