Wow, that trailer completely changes my original perception of the movie. It's going to be more like a traditional kaiju-on-kaiju Godzilla movie. Now I really want to see this movie.-Ed
Interesting. I like it. The other Kaiju, in 'flight mode', reminds me a bit of Mothra or Battra, although considerably less colorful.
At first I thought it was Rodan. But I've been reading that it's Muto.
