Cool pictures Brian - thanks for posting. I got a little schoolgirl giddy just looking at Cap and Iron Man in the same scene on that first picture. I love that Hawk and Thor are in there too, though I'd much rather see Wasp and Giant Man in place of Hulk or Black Widow. No offense meant to Scarlet - it's just that the Black Widow has always been more of a spy character than a super-team character in my mind. I always felt like Hank Pym and Janet Van Dyne provided more character driven storylines, with their rocky marriage issues, Janet coming from money, Hank being a flawed husband and hero, and obviously the creation of super baddie Ultron, which leads to characters like Vision, Jocasta, etc.
I guess the Black Widow can provide some connection back to SHEILD, and maybe even a question of her true loyalties if she has to choose between the two. But I completely forgot that Hulk was going to be in this and find myself extra annoyed at his involvement.. Is anyone else bothered by Marvel's determination to promote the Hulk? He's had two failed movies, doesn't seem to be high in the Avengers fan base, and his powered-character doesn't seem like a good fit for a super-team. I hope they somewhat stick to the comic origin, using Hulk to initially bring the heroes together, then quickly drop him from the lineup. Hopefully characters like Vision, Black Panther, Scarlet Witch, Black Night, Wonderman, Ms. Marvel, etc. can take his place in the sequels.
