Coincidentally after posting on Coraline I came across Jon Klassen's work, and it just so happens he worked on the visual development for the movie for a little under two years. What an amazing project! So much work goes on behind-the-scenes of movies, I love seeing snippets of this sort of thing, often the forgotten work or pieces not usually shown to the public.
I really enjoyed looking through Jon's portfolio of work, he has quite a unique style. There is also a great interview with Jon on Illustration Mundo.
