Josh Brolin as Thanos

There are a lot of theories swirling around Avengers: Endgame. Fans can't seem to stop speculating on what will happen in the upcoming sequel to Avengers: Infinity War, which might see the death of a number of fan-favorite characters, as there are several actors who are at the end of their contracts with Marvel Studios. Don't feel bad if you can't keep all of those theories straight. Here's a guide to some of the most popular fan theories about Endgame.

The central role of time travel in the film is one of the most popular theories, and there's a lot of evidence to suggest that going back in time will play a key role in defeating Thanos and reversing the effect of the snap. However, exactly how that will occur remains to be seen. Most people seem to think that Ant-Man, who was seemingly trapped in the Quantum Realm at the end of Ant-Man and the Wasp, will be one of the big drivers behind the use of time travel, and a new leak concerning Captain America's costume seems to lend further evidence that the Avengers will head to the Quantum Realm.

Endgame will serve as the end to Phase Three of the Marvel Cinematic Universe. The events of that movie will have massive ramifications for Phase Four and beyond. Phase Four itself is set to start with Spider-Man: Far From Home. Considering Peter Parker/Spider-Man was turned to dust at the end of Infinity War, it seems pretty likely that the snap will be reversed in someway.
