Kevin Feige, the President of Marvel Studios, has made it clear over the past few years that all of the Marvel movies are working towards a final goal. The films in the Marvel Cinematic Universe so far have done a pretty good job of having standalone stories while also knitting the whole together like serials. Earlier this year, the MCU was opened up into the rest of the cosmos with Guardians of the Galaxy, which established many more heroes and villains that we can expect to be seen in future Marvel movies.
However, director James Gunn has indicated that doesn’t necessarily mean the Avengers and the Guardians will cross paths anytime soon. “We really are separate from the Avengers,” Gunn said in an interview with Screen Junkies, “and I don’t think people should assume too many things about the Guardians play in all this. We have our own galaxy to take care of. We have our own galaxy to save. Earth is the Avengers’ province. Thinking that everything is going to come together in a perfect way is not necessarily the way it’s going to happen.”
I don’t think of this as him saying that the two aren’t even in the same universe, but they probably won’t work together anytime soon. The Guardians have their territory to protect and the Avengers have their’s. That doesn’t mean the two couldn’t eventually crossover though. Guardians of the Galaxy introduced a lot of important details for the future of the MCU, specifically Infinity War. Maybe if Thanos is threatening the whole galaxy, then they will have to come and help out the Avengers.
Avengers: Age of Ultron is set for release on May 1, 2015.
