The Guardians of the Galaxy.
According to one of the more reputable film sites Latino Review, they are reporting that not only is the second Marvel film of 2014 to be Guardians of the Galaxy, but it will also feature Thanos. Thanos we all know will be the villain of the next Avengers film. This film would be based on the 2008 lineup of Guardians.
I don’t know if this is true yet, because Disney hasn’t spoken on the issue yet, but I can definitely see it. The best stuff about Thor was the Asgard stuff, and with Marvel, so much of what they will be doing in Avengers films is otherworldly, so why not add a bit more context to the cosmic layer of the Marvel Film Universe? My only issues:
-Guardians are made up of second and third tier characters, and theres very little familiarity with the product.
-I hope it doesn’t come at the cost of the Black Panther film. It could very well be the Avengers’ Batman. Shoehorning him into the sequel really doesn’t work if you are focusing so much on the expansion of the cosmic stuff. The only thing that would make sense at this point would be putting him in the next Captain America film as Cap is now in the modern day and his shield is made of Vibranium which is found is Wakanda. I wouldn’t love that cause the tonal differences of Cap and BP are very different. It’s like Superman and Batman. It would take a very deft hand to meld those two.
Again, this is all unconfirmed at this point, but it’s worth thinking about.
