A lot of the time in animation is spent getting the story right - that's something you can't rush.
Every movie goes through that U-shape where you start with 'Oh that's a great idea. I love it.' Everything's possible and then you face 'Oh, we can't do that, and that's impossible, and that's a bad choice.' You go the practicality of it. And then you come up to 'Great.' But that middle part is when you don't have results yet.
I'm a very soft-spoken person. I don't throw furniture. I don't throw tantrums.
When you make a movie, it's just so personal and then you put it out in front of people and it becomes something else.
I'm not aggressive by nature and it was tough for me to make the transition to directing.
