For those still wondering about the music heard in the trailer...Hans Zimmer posted in a forum that it was indeed from his score, and it was a slightly recut version of a longer track. He also used 15 drummers in the recording sessions. As a huge Zimmer fan, I'm really excited to hear the score. What I heard in the trailer was an exciting tease.
Those photos are awesome...I have no problems with the costume whatsoever, and Zod looks fantastic.
