It's weird - on almost every film I've worked on, the first sequence we storyboard ends up being the first sequence that goes into animation, and ends up being almost shot-for-shot the same.
Back in the days before the Internet, there was no place to put a short film, so Mike Gribble and Spike Decker had this festival of animation. My student films got selected.
I wanted to make sure that 'Up' wasn't a 3D movie about a man who sails his house to South America. It's a movie about an old man who sails his house to South America that also happens to be in 3D. So the first thing is always the story.
I loved 'Dumbo.' I watched Bugs Bunny time and again. The Muppets were big, too. All of those, they have this real, not darkness but poignancy, that's what makes it stick with you.
As a director, nobody told me I'd be talking to people all day. I'm naturally reclusive - I feel myself peek out at a certain point and go, 'All the extrovert in me is done! I'm on reserve!'
There's that bubble of childhood that makes you innocently do anything. Then, when you get older, that pops, and you're aware of limitations and judgment and social pressures and things like that.
