Godzilla's Asia trailer confirms some other monsters will be in the film as well as some stories online from writers who've seen footage from the film. Oddly enough, the new monsters are called Mutos and one looks shockingly like Rodan. Here's to hopes that the film will be less talking and more monster vs monster fighting.
Strangely enough, Japan doesn't get a first run of the film. It'll will be distributed by Toho as usual, but won't come to them until a few months after it runs in America. Bad negotiations Toho.
