Here's the first trailer for The Dark Knight Returns. Like The Hobbit, this is going to be split into two movies. Okay, not like The Hobbit. But it's worth pointing out, this trailer is just for the first film, the first half of the story.
Peter Weller is providing the voice of Batman, and very well, I think.
Okay, the animation could be more polished, and the designs aren't quite as striking as the original comics, but this doesn't look terrible, not by any means. Possibly because I know what the actually narrative entails.
