The Japanese trailer for Brave features lots of new footage, hints of several new plot elements, and some really breathtaking shots. Their new poster is nothing to be sniffed at either. And… judging from these, it seems that film is being called Merida in Japan.
That promo seems to confirm a number of rumours about the film, and if you've heard them too, I think you'll know what I mean. It also seems to feature dialogue from Mordu the bear. Make of that what you will.
You can see a better quality version of the same video at Disney's Japanese site though I've had a bit of trouble getting it to play smoothly and it doesn't have subtitles.
