On April 27, everything will change. At least for the Marvel Cinematic Universe, because that's when Infinity War comes out. Throughout the promotion of the film, everyone involved has promised thatthe third Avengers movie will be totally unexpected, but seeing as a few Avengers: Infinity War theories are really scary, you should probably count on getting a little jumpy at points.
First of all, Infinity War has to be terrifying because of its Big Bad, Thanos. He's already called the most powerful villain of any Marvel movie, and it's safe to say that he won't stop at anything to collect every Infinity Stone. As for the Stones, a few characters who possess the prized gems are in major jeopardy. Just take Vision, who has the Mind Stone implanted in his forehead, making him one of the most at-risk superheroes of all.
That doesn't mean that the others are necessarily guaranteed to get out alive, though. In fact, the opposite might be true, as the filmmakers behind Infinity War have made it clear that they won't be afraid to kill off major characters. If they're going to be so liberal with killing people off, who's to say that they will also make sure that Infinity War stays totally easy to watch at all times? They probably won't, so you might want to prepare yourself for some of these super scary fan theories that may or may not play out in the epic movie.
