More action shots! More character building shots! More of that cool ass mofo Samuel L. Jackson! More Hawkeye! OMG! Its Pepper Potts! More of those mystery aliens (director Joss Whedon says its not the Skrulls or Kree but another Marvel U alien race; I think it may be the Badoon)! And the motherfreakin’ S.H.I.E.L.D Heli-Carrier!!!!!!
Plus that Japanese voice-over guy is all sorts of awesome
