I've been a big fan of Wes Anderson's work for a long time now, and I was elated to hear his next film would be another stop motion piece. Wes being a director who clearly goes out of his way to have his sets and cinematography comply with his iconic style and aesthetic, I'm guessing that after Fantastic Mr Fox that he realized he could not only control the set of his film's in stop motion, but the entire world. So now instead of making the interior of a room or a train look symmetrical, he could make everything on screen visually perfect for him, as seen in Fantastic Mr Fox, thus giving really bringing his style alive.
One of many great shots from Fantastic Mr Fox (2009) showing an entire symmetrical landscape.
I'm also excited to see this film adopt a Dystopian, and not too distant Japanese future setting (although visually the design of the universe seems to be old mixed with new, reminiscent of the Fallout games series) which is a world and culture I always find interesting to see western portrayals of. And also I just love dogs a lot, so to see all these great characters in these dogs is just fantastic!
