Apparently Amazon.com asked "Coraline" director Henry Selick to write a one-off guest blog entry about the inspiration for and genesis of the film. In case you've been trapped in a pocket dimension or fighting evil sex vampires on a remote island for the past year, "Coraline" is beautiful, and definitely worth seeing for the inventive stop-motion animation.
You can read the rest of Selick's guest blog for Amazon here. It's consistently entertaining and clever, and gives some important glimpses into the process of making the film. The passage where he lists some of the different ways the film could have come out if it had been green-lit earlier is a pretty fascinating look at how industry forces can shape a movie - in this case, for the better!
