The Avengers are going to space, y'all! This morning Marvel had a "secret" event that opened the floodgates to SO MUCH new information. One of the announcements was that Avengers 3 will be split into two, yes TWO, parts and that it's going to be based on the Infinity Gauntlet storyline. We've got the Infinity War, people!
So what does this mean exactly? Well, a few things.
This is going to be a huge, ensemble movie that's going to blow the roof off of everything and the minds of everyone! The Avengers might be able to fight off some villains like Loki and now, presumably, Ultron. But how will they stand up against Thanos? Even with the Guardians on their side, this will be a challenge. And it looks like Thanos finally got ahold of the Infinity Stones.
Also, the cast is going to be big, but the story will be equally big. Considering Marvel has decided to split up this massive cinematic event into two huge movies, it's safe to say that a LOT of stuff is going to go down in [The Avengers: Infinity War](movie:738027).
Furthermore, since Avengers: Infinity War will be coming out after, the now officially announced, [Captain America: Civil War](movie:994409) we can bet that Earth will be in a state of disarray. Meaning, for lack of a better phrase, shit is going down.
Avengers: Infinity War Part I will be released in May 2018 and Avengers: Infinity War Part II will be released one year later in May 2019.
