I said before that I'm a sucker for stories about kids that get transported into magical worlds. Arthur and the Invisibles looks like a great example of that kind of story done perfectly as a movie. Arthur inhabits a beautifully photographed, live-action world until he enters the world of the Invisibles where he's converted to the same, stunningly detailed CGI that they are. The trailer's got a fantastic, storybook quality to it.
And David Bowie voices the bad guy.
