Avengers 4: 11 Insane Trailer Rumours You Need To See

11. It Will Confirm The Avengers' Use Of Time Travel

It's Hollywood's worst-kept secret right now that The Avengers are almost certainly going to be using some form of time travel to stop Thanos in Avengers 4, and if the leaks are accurate, the first trailer won't remotely attempt to shy away from this fact.

One rumoured trailer synopsis states that it will show Tony Stark (Robert Downey Jr.) and Scott Lang (Paul Rudd) using some mysterious new technology - presumed to be the B.A.R.F. tech from Civil War - to manipulate the quantum realm and travel back to the past, where they will end up in the Battle of New York.

The trailer will also include glimpses of Thor (Chris Hemsworth) and Loki (Tom Hiddleston) teaming up to fight off the Chitauri, counter to Loki's antagonistic stance in the original version of the battle.

The real kicker, though, is that the trailer's final shot will reportedly show one of the Infinity Stones disappearing from Thanos' damaged gauntlet, suggesting that the crux of the movie will be The Avengers travelling through time to re-acquire the Stones all while the Mad Titan attempts to stop them.

This certainly doesn't contradict some of the photos leaked from the Avengers 4 set so far, so it sounds pretty damn plausible.
