Minus the first footage, you can watch Zack Snyder and Henry Cavill at last night's San Diego Comic-Con Man of Steel Panel.
Snyder talks about how awesome Superman will be and more, with Henry Cavill very humble about playing Superman.
Oh, and the teaser footage is online if you know where to look. Sorry, not on Cosmic Book News, but you can read a description here.
Thanks to GeekTyrant for putting these together.
