Now we get to the biggest talking point of the trailer, Godzilla's beam charges up purple! In my humble opinion, I don't think that we are actually getting a fully purple beam but the glowing purple images are extremely striking. I think that the beam is going to start out purple at the base of his mouth and then turn blue as it goes farther out from his mouth. The reason he charges up purple is of course because this Godzilla is constantly glowing red. Red+Blue = Purple. This would also make sense given that a purple chemical flame is hotter than a blue flame, so naturally the farther the beam is from the source (Godzilla's gaping maw) the cooler and less intense the beam will be.

Now finally we have some shots from the little behind the scenes morning show clip. All of the good images are super far away shots to show the scale of Godzilla as he comes ashore. Please excuse the poor quality of the images and the little bits of text that sneak their way into the images.
