So... Marvel Films got the entire "hero cast" of The Avengers up onstage at Comic-Con. Everyone was expecting it, but it's still pretty incredible that this is actually happening.
Also incredible yet wholly expected: Mark Ruffalo is the new Hulk, Jeremy Renner is Hawkeye, and Joss Whedon is directing.
There were also teaser trailers and rough scenes shown for "Thor" and "Captain America," and from Slashfilm I find some details from a "Cap" scene they showed revealing A.) one of the ways Cap will tie in with certain other Avengers characters (what sort of mythology was it Nazis were obsessed with, again? Heh.) and B.) which HUGE piece of the Marvel arcana is playing a previously-unmentioned part... and my mind is now BLOWN!
