I've certainly seen R&D groups, typically funded by large corporations, where they bring together a lot of smart people and nothing happens. And the reason nothing happens is that they don't have a clear goal.
Every Pixar movie has its own rules that viewers have to accept, understand, and enjoy understanding. The voices of the toys in the 'Toy Story' films, for example, are never audible to humans.
In the early 1970s, I headed to graduate school at the University of Utah and joined the pioneering program in computer graphics because I realized that's where I could combine my interests in art and computer science.
I don't think most of our films should be realistic, but you want that as an artistic possibility. Then, the artist can take the realism of the world and push it in ways that we can connect with.
The problem is some of our riskier films just don't make as much money. But if you only make films that will just be commercially successful, then you can also sink yourself as a studio.
The need to challenge the status quo is just more obvious when you're failing than when you're succeeding. But it's no less urgent.
When companies are successful or not successful, they almost immediately jump to the wrong conclusions about how they got there or why they got there.
For me, one of the great tragedies is the conclusion studios have drawn about traditional animation. I believe that 2D animation could be just as vital as it ever was. I think the problem has been with the stories.
If you put out 20 films, you hope that a number are successful. It's like human reproduction versus frog reproduction. Frogs produce thousands and hope a few succeed. Humans don't produce many babies but put a lot of energy into them, which is kind of where we are. They still don't always succeed, but you try a lot harder.
With certain ideas, you can predict commercial success. So with a 'Toy Story 3' or a 'Cars 2,' you know the idea is more likely to have financial success. But if you go down that path too far, you become creatively bankrupt because you're just trying to repeat yourself.
I started off life at Pixar with interesting technical problems. But as time has moved on, I found that the social and management problem was far more complex and interesting.
Look at the computer industry. I've watched a lot of companies come and go, some that were right at the pinnacle of their success.
While problems in a film are fairly easy to identify, the sources of those problems are often extraordinarily difficult to assess. A mystifying plot twist or a less-than-credible change of heart in our main character is often caused by subtle underlying issues elsewhere in the story.
I exercise in the gym about three times a week. I vary the workout every time, but I'll always do some type of circuit work with weights. It gets my heart rate up without putting too much stress on my knees, which for some reason seem to be older than the rest of my body.
