I thought this was going to be sometime during the end of 2011... I have been waiting for something about this series.
It looks like the movie is a compilation of the entire series, with a few new bits and pieces added in.
It's interesting, and I want to see it, simply because I think the T&B world is awesome.
I wish there were subtitles for this one...
Here's another one, with Kotetsu as the main focus. [link]
