I hadn't considered Selick for this, but that's a great choice. I was all excited about Jordan, but now I kind of want that, too.
I really liked Graveyard Book (got a definite Ray Bradbury vibe from chunks of it) and I was amped it won the Newberry. The film has a lot of potential (especially in the casting; I'd love to see an all-star team of British character actors for the occupants of the cemetary) but it also has plenty of places where it could go wrong, starting with the structure. Like Jungle Book, there's a storyline weaving throughout but most of the chapters are relatively self-contained, almost like a collection of short stories. It's one of the charms of the book and is part of what makes it a good read. But the storyline that Gaiman keeps coming back to is kind of predictable, even if it ends well.
But yeah, done right, this could be very very good.
