They let you adjust the season's episode count and shift around scenes that would have been the end of this season to the beginning of next. So you're actually going to have more time to tell some of the stories.
Gaiman: The hardest part of writing the novel was the page count. I mean that very literally. The book that I handed in was probably 700 pages, 200,000 words. I was told immediately that I had to find 50,000 words to cut, and I managed to negotiate them to 20,000. But even then, it was considered a ridiculously long book. I went back in on the 10th anniversary version a few years ago and filled it with stories from the past that I didn't get to tell.
I had dinner with Bryan the other night, and we talked about what we would do if we get a Season 2, and I was all, "I would love to do this story about the kitsune," that simply didn't get written before. I had plotted it for the novel, but then realized I needed to start cutting stuff, and I didn't want to write a 40-page story that wouldn't see print. And Bryan got very excited about it. That kind of thing is just really fun. We can do all of this stuff -- we can do everything. It's a huge canvas.
I think we can get probably five seasons out of the book, just because every time we put a new piece on the board, we go and spend time with one of the pieces we normally don't see. While the giant shape of the book does not change, what happens will change. And sometimes we want to put in things that are not in the book. If you've read the book, you will have a major advantage over somebody who has not read the book. However, we do not want you to be complacent, and there are definitely places where we would like cliffhangers, where your knowledge of the book avails you nothing.
