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.

One of those strange things that happens in movies is that you need someone to actually say people's names, or else you have no idea who those kids are. This was a way for her to introduce who the important boys were in the story, but then it just was so funny that it became a centerpiece to it. When you look at the character design that Tim did for Weird Girl, and what Catherine [O'Hara] did with the voice, and it's gonna kill.

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.

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.

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.

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 loved The Sarah Connor Chronicles that Josh did, and I loved that it was a family drama with a huge, different element. And this is also a family drama with a huge, very different element. I think he'll kill it. It will be great.
