As far as the Avengers film goes, it seems as though we have a roster; not that it was hard to figure out! Feige cites many of the characters that we can expect to see in the upcoming film.
I think we know. It’s going to be Iron Man, Thor, Captain America, Nick Fury. I think it’s safe to assume that there will be some members of the Hulk universe in the film as well. In terms of the additional, I think Black Widow for sure. SHIELD’s organization for sure. And, again, what’s exciting to me about the Avengers movie are seeing those four characters together and interact with each other.
The question that many fans may be asking, however, is whether or not we will be seeing the Hulk as a staple character in the upcoming film. Based on the hints the Feige was dropping during the panel, according to slashfilm.com, it is possible that we might be seeing him as the film's initial villain. Marvel seems to want to be keeping things as close to the comic books as possible, so it might be possible that we may be seeing some Skrulls in the upcoming film.
The upcoming Captain America film will most likely be a period piece, and focus on the Cap's World War II era days, where he fought alongside the Invaders.
Setting it in the Marvel version of WWII is going to open it up [to an international audience] in a big way. It’ll actually end up being our most diverse and our most international film. In terms of the cast there’s a group that [Cap] works with that will have an opportunity for much more international casting.
Feige also mentioned a few of the characters we will be seeing in the upcoming movie include Howard Stark, ( Tony Stark's father,) as well as an introduction of the Hydra organization.
It looks to me like Feige has made it his goal to maintain a clear and distinct association with the continuity we have seen in the Marvel Universe, and ultimately I feel that is what will make the Marvel franchise films a huge success. The more I hear about these, the more excited I get to see them play out on the big screen. How do you guys feel? Are you excited? Do you think that the Marvel film producers want to keep things as close to the comic books as possible?
