This morning the first trailer for Guardians of the Galaxy was released. For those of you unfamiliar with who these Guardians are, they are group of heroes from Marvel comics who travel around the galaxy. The original Guardians of the Galaxy were from a thousand years in the future, but this movie is based on the newer incarnation of the team that is based in the present.
Check out the trailer here:
This is an interesting addition to the Marvel film universe, as it does not right away seem to fit in with the basic Avengers theme. It slightly crosses over with the Thor movies (I know that The Collector was in both Thor: Dark World and will be in GotG) and may end up with some connections to the end of the first Avengers movie. I don't see anything in this movie fitting in with Avenger: Age of Ultron, which is the move all the other movies are building up to.
My present theory is that they are putting all the pieces together for an Infinity Gantlet movie to be the end of phase three. The Avengers, Thor: Dark World and GotG all would seem to fit together for that. I am expecting to see more hints for that in the next batch of films. I very much could see them fitting some connection in to the forth coming Dr. Strange movie as well as Thor 3.
This is my speculation on what I want to see as well as what I think would make the most sense. All we can do now is wait and see where it all goes. Right now we have Captain America: The Winter Soldier to look forwards to here in just a few months.
