UPDATE: If the above video clip doesn't work, you can check out a beautiful hi-res version of it at the Apple site.
This trailer piqued my curiosity. How does a film, which will run (most likely) approximately 90 minutes, stay true to the narrative of a 37-page children's book?
I've just looked through my copy of Where the Wild Things Are by Maurice Sendak, and I've estimated that twenty-seven of the pages are illustrated. (Some are image only, and on others, the image takes up most of the page with a bit of accompanying text.)
The best films-based-on-books capture the essence of the book. While most novels' plots are too extensive to show completely within an acceptable movie time limit, a film's story—sincerely told and authentically rendered—can do the original work justice.
The trailer shows so much not even hinted at in the original. I'm keeping my fingers crossed that the film stands on its own—I'd really like to see this!
