Yes, the first job I had at the studio was Snow White. I don't like the term particularly, but I got stuck with the human characters. They just didn't have that many people who could draw humans.
They all matter to me, whether I'm working on a Sam Jackson film for a week or I'm the star of my own TV series - I take it all very seriously, and I have a healthy respect for the work in general, despite the role.
And the funny thing is, I've always been an optimist - it's practically a congenital disorder with me.
