I just always remember myself as the teenager with questions about movies and screenwriting. I would hope that there was somebody out there who would answer those questions, and so, if I can take a few minutes to do it, I will. It's not threatening for us. We're not being stalked, so it's easier.

Now, it's common knowledge that most towns of a certain size have a witch, if only to eat misbehaving children and the occasional puppy who wanders into her yard.

For Charlie and the Chocolate Factory, he came to me and said, "I want to do everything that's in the book, and as much more as you need, so that it all makes sense." I was like, "Okay!" And then, I would pitch back to him my love for Charlie Bucket's family and how lucky Charlie was, and that I felt so bad for Willy Wonka, shut up in his factory, all alone with these crazy Oompa Loompas.

I convinced Tim to add one song, and then we added five. We changed a lot of things while we were shooting, which you should never do in stop-motion animation. With this, it was a much smoother ship, so I wasn't getting sent the scratch reels of things.

I often say that a lot of my job, as a screenwriter, is sort of being a stock picker, in that I need to figure out what movies are probably going to get made because otherwise I'm spending a lot of my time on something that's trapped in 12-point courier. So, having Tim's interest in doing a movie is a huge asset. But, not everything shoots. I'm always grateful when those things do happen.

Frankenweenie is also about mortality, but at a very different stage. It's losing a parent versus losing a dog. I don't run away from the tears of that, which I think is what makes it feel universal.

With Corpse Bride, I saw a lot more of it during the process because we were changing things a lot. When I came onto Corpse Bride, it wasn't a musical.
