Newsarama.com posted it's 10 to Watch for 2014: MOVIES, in the description for it makes note about the monsters Godzilla would fight the Mutos and seems to give away info on just what they are. Whether they are being creative or this is actually how and where they come from we shall see below is the post.
Born off the coast of Japan in the aftermath of a nuclear explosion, the lizard-king Godzilla returns to theaters in 2014. Directed by avowed kaiju mega-fan Garth Edwards (Monster) with a final script by Frank Darabont, this new film coming on May 16 looks to crush earlier renditions of Godzilla and leave Godzilla-sized footprint for a new generation.
In this new Godzilla, the monster known in Japan as Gojira will be fighting against test-tube monsters, dubbed Mutos, created in a secret government lab that threaten to take over the world. Godzilla’s cast is a veritable goldmine of acting talent, with Breaking Bad’s Bryan Cranston and Kick-Ass star (and future Avenger) Aaron Taylor-Johnson leading an ensemble which includes Ken Watanabe, Juliette Bionche, Elizabeth Olsen (also a future Avenger), and a staple of the Godzilla franchise, Akira Takarada.
Edwards’ Godzilla is coming out on the 60th Anniversary of the titular lizard’s birth.
