The guy is in the cover art of the video. Is there any need to hide out his name?
It looks like a good balance between serious and dramatic and fun and campy.
It struck me how terrible Tony Stark's character looks like in the trailer. After what seemed to be quite a bit of character development in Iron Man 3, he's back to his man-child state with quips that only five-year-olds would cheer for. Earlier - in the previous movies - his immaturity was somewhat cute; now it's frustrating.
