This is a new Marvel movie due to be released. A lot of hype has been building with Iron Man 2 in 2010, and Thor and Captain America in 2011. They will be great movies but will also pave the way for the historical blockbuster the Avengers will become. This will be the first picture produced by Marvel that's distributed by Disney.

Edward Norton (who played the Hulk in the last Hulk movie) has been ditched due to issues during negotiations, Mark Ruffallo is playing as The Hulk.
Joss Whedon as The Director. Best known as the Creator of the "Buffy the Vampire Slayer" TV show.
As you can see Joss Whedon is an excellent judge of character and has a very good eye for talent from previous work.............
This alone is very encouraging. But eh...maybe I'm getting off topic :)
Joss Whedon had tears in his eyes. He said, "I had a dream all my life and it wasn't this good." And 6500 hundred people in Hall H screamed from the very depths of their multiverse-loving souls. The Avengers had assembled. And just like that they were gone. After seeing the footage of Captain America and Thor they had a job to do: to prepare to shoot the greatest comic book movie in the history of time.
Avengers comics have been all over the Marvel Universe and as a result, the storyline could really go a lot of places.
There are several rumors of the storyline. One that could be a likely rumor is that because of his appearance in the movie despite the complications in casting. The Hulk may be the main villain as he is clearly vital to whatever they have planned. There has been many villans in the history of the Avengers however. I'll update this as I find out more.
Heres a Teaser trailer that has been released. I'm going to be following this and updating any news that becomes available as the release date May 4, 2012 approaches.
I'll keep you updated
