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.

You know something has really stuck in Tim's head when he's drawn what the character looks like. Weird Girl and Elsa actually switched places, at one point. I may be mis-remembering it, but the original design for Weird Girl was actually Elsa, but then it became Winona Ryder's character, and the new Weird Girl was just fantastic with those giant wide eyes.

I knew that this was the movie in which a lot of the cinema version of Burton-esque first started. So, I knew that there were things that were hugely important to him for it, but it didn't really feel that different than working on any other of these projects.

You're looking, moment by moment and scene by scene, how you can tell the most interesting story. So, we had this great short and we knew that we had a story about a boy and his dog. Because we had that pure emotional core, we could go on crazy tangents and always come back to Victor and Sparky. When I wrote in stuff like Weird Girl and the cat poop, Dutch Day and the windmill, it felt like it was part of Tim's universe.

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.

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.

Preacher is a great frustration because I thought it was done, and then it got put in the press notes for the [Frankenweenie] junket and everyone started asking about it again. Preacher could be filmed, at any point. It's sort of ready to go, but it's lacking a green light. At some point, that green light might come, but it may never come. So, I have to allow for the fact that I've done everything I can, and whatever happens with it, happens with it.
