Ah yes, the other DC superhero flick I'm dying to see. Bit early for teaser artwork, perhaps, but never too soon for a little aesthetic fanboy slobbering.
The shield is modeled after the new costume - not that you can really tell, what with all the flames and the zooming and the ka-POW and whatnot - and the overall look is inspired by opening credits of the Christopher Reeve movies, and Superman Returns. A contradictory notion, I know, given the clear intent to move away from established film continuity. That said, I hope and pray they carry over the John Williams theme. Call me stuck in the past, but that music is every bit a part of Superman's character as his cape.
So yeah, I'm excited for Man of Steel, and I think Zack Snyder might just be the perfect man for the job (even after that slight hiccup with Sucker Punch), and I direct any doubters to the movie Legend of the Guardians, which almost prophetically demonstrates the staging of action sequences based on flying. Also having recently seen Immortals, Henry Cavill has my full support as Supes himself.
Great poster, and I totally agree with you about using John Williams's theme. Just because they're updating it doesn't mean they should scrap the music, just update it!
Coolest teaser I've seen in a while, professional or otherwise, that I can remember off the top of my head. Man, it would be amazing to see a Captain Marvel movie open with this much style and flair.
Great poster anyway. Insert the John Williams music here.
Offtopic: You didnt like Sucker Punch, but like Immortals? Whats wrong with you?
