In some ways, I feel like the strength of animation is in its simplicity and caricature, and in reduction. It's like an Al Hirschfeld caricature, where he'll use, like, three lines, and he'll capture the likeness of someone so strongly that it looks more like them than a photograph. I think animation has that same power of reduction.
For me, geopolitical issues are becoming more important, because how can you understand economy if you don't understand geopolitics? People think economists just deal with spreadsheets and charts. That's a narrow-minded caricature.
Animation is different from other parts. Its language is the language of caricature. Our most difficult job was to develop the cartoon's unnatural but seemingly natural anatomy for humans and animals.
Researching real people and doing them, I think, is harder than anything else. You don't want to do a caricature of them and you don't want to do an impression. You just want to do the best you can, in terms of presenting their views and a general impression of the guy. That's the hardest thing to do, real people.
The best portraits are those in which there is a slight mixture of caricature.
