Updated: Thanks to Twirrim for pointing out Nathan Fillion's latest twitter update, confirming Whedon's comments were just a joke. Whedon did however confirm that Jeremy Renner was playing Hawkeye, something we were sure of anyway but it's nice to get confirmation from the director. Might we hear more at today's panel? Breaking: At the Joss Whedon panel today, The Avengers director apparently name-dropped his Firefly star Nathan Fillion as his Ant-Man - however there's some conflicting reports as to whether it was just Whedon not being serious (given that Fillion's a friend and a fan favourite for the role) and it was all just an obvious joke. We need some clarification on this. I'm scowering the web for more reactions on what Whedon said, and how his tone was. Comment now if you were there and let us know!
