There have been a great many Man of Steel trailers, but since you haven't seen the entire movie in promo form yet, here's one more. It seems highly likely this one is somewhat spoilery, so proceed at your risk. It's mostly dialogue-less (this has been the most stringently epic series of trailers ever), but you'll get to see a newborn Kal-El and lots of destruction. This movie will be stratospherically high on destruction. Oh, and have we seen Diane Lane as Ma Kent yet? If not, here she is.
