Big Fish was the first movie that we worked on together, and I had already written it. We had another director, but that director didn't do it. So, it was just a Hail Mary to Tim, and Tim said that he wanted to do it and I was like, "That's fantastic!" But, there wasn't a lot of collaboration because he knew what he wanted to do and just did it. There were very minor changes for Big Fish.
