I just saw it last night.....man.....it was awesome. Jeff Bridges is an awesome bad guy....and RDJr is the perfect Iron Man. Tom Cruise is a good actor despite his nutzoid mind, but I don't think he would fit the role.

So yeah, it's was actually announced a while back about Captain America, Thor, and Iron Man 2. After that's done they will go with the Avengers movie...

Captain America
Thor
Iron Man
Hulk - I think he was an in and out team member
She-Hulk
Hank Pym (Ant-Man)
and a few others

And....for some reason Beast is part of the Avengers as well. I stopped reading comics in 1996 so I don't remember seeing Beast in the roster.
