I knew that Weird Girl was going to be kind of amazing. The secret truth of Weird Girl is that I put her in there originally because I needed some way to set the boys' names.

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.

Most times a person grows up gradually, but I found myself in a hurry... Hoping to find an answer, I uncovered an article about the common goldfish. "Kept in a small bowl, the goldfish will remain small. With more space, the fish will double, triple, or quadruple in size." It occurred to me then that I was intended for larger things. After all, a giant man can't have an ordinary-sized life.

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.

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.

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.

When Tim asked me to do Frankenweenie, he had his original sketches from before he did the short, of what Sparky looked like, and he drew Victor and some of the other crucial people. The remarkable thing about working with Tim is that, once he's read a script, he sketches out everybody else.
