Picking up various bits of info at the moment, but the confirmation comes courtesy of Whedonesque.
When asked about the film, Whedon said..
"It’s not an official thing, I think because Marvel couldn’t afford a press release, Can I make that an official thing? I am directing THE AVENGERS!" -
Its no surprise of course, but nice to have it FINALLY confirmed. Marvel for whatever reason, have never sent out any kind of official press release.
Whedon also says:
"I started to work on an internet piece with Warren Ellis called Wastelanders, but then Avengers came up and he said 'I'll just wait then." it's a little early, I am still writing an outline and reworking it. What interested me is these people (Avengers) shouldn't be in the same room as one another & that to me is the definition of family"
"i honestly watch (JJ's) Star Trek and its the gold standard for a team movie/summer action and it makes me throw up w/fear about Avengers"
The EW panel with Whedon and JJ Abrahms is currently underway, but both are now discussing their next projects,
Super 8(Abrams) and
Cabin In The Woods(Whedon). If any more Avengers related stuff comes up I'll update so keep your eyes peeled.
