UPDATE: Marvel has released the first official image of the entire cast together on the Comic Con stage. See above.
The Marvel panel was packed, loud, opinionated and hungry. We'll have footage reports on Captain America: The First Avenger and Thor in a little bit, but first, as expected, the full cast for The Avengers was officially announced by Samuel L. Jackson and Robert Downey Jr. And they are:
Samuel L. Jackson as Nick Fury
Robert Downey Jr. as Tony Stark
Clark Gregg as Agent Coulson
Scarlett Johansson as Black Widow
Chris Hemsworth as Thor
Chris Evans as Captain America
Jeremy Renner as Hawkeye
Mark Ruffalo as Bruce Banner / Incredible Hulk
Joss Whedon, Director
Joss Whedon: "I have had a dream all my life and it was not this good." ..."This is The Avengers; a team is more than the sum of its parts -- this cast is more than I could have ever hoped for ... and I am going to blow it. I need your love; I need your support."
