Now that I think about it, has there ever been a movie about anthropomorphic wolves before?
I don't remember any.
The only one I can think of is Balto 2 if you're looking for wolves being the subject. One Stormy Night and Ringing Bell of Chirin COULD count since they both have a wolf as the main character.
Either way, this movie looks like shit. The designs are awful and the plot is already being made http://www.youtube.com/watch?v=qPqwlgqO_x0 .
