Klaatu vs. Gort?

This trailer is the first one to suggest Klaatu is at odds with Gort. Also suggests destruction of Earth gets underway and Klaatu, seeing the error of his ways, attempts to stop it. It's been quite a while since I saw the original 'The Day The Earth Stood Still', and can't remember this element. Seems like they decided to spice things up. I like it, though. Clicks. Holding my breath.
