Even more than the trailer, MCU fans are desperate to know what the title of Avengers 4 will be. A few weeks ago the Russo Brothers posted a teaser photo asking fans to “look harder”. While some people did notice the two A’s in the image, they believed that meant it would be called Avengers: Assemble; although that was the title they used to market the first Avengers movie in the UK.
According to a source who is most reliable, the title for the conclusion to Avengers: Infinity War is Avengers: Annihilation.
It’s right there in the Russo’s photo as well. The two “As” flanking Joe Russo as he works on his laptop. Instead of being “Assemble” like people believed, it’s “Annihilation”.
The title is pretty smart. It’s grounded in what we just saw happen in Avengers: Infinity War where the Avengers (and the entire universe) experienced Annihilation. It also could hint at what’s going to happen in Avengers 4 and what the heroes are going to have to go through and sacrifice to reverse what Thanos did.
It also continues the Avengers tradition of using titles of big events in the comics, although the comic Annihilation wasn’t an Avengers book rather a huge (and awesome) cosmic Marvel event. The previous two Avengers films, Age of Ultron and Infinity War, also took their names from big story lines in the comic without having much to do with the comic story. The comic version of Age of Ultron was an alternate future ruled by Ultron, while the Infinity War comic was a sequel to the events of Infinity Gauntlet.
So there you have it. As of a few months ago the title for Avengers 4 was Avengers: Annihilation and the “AA” in the Russos’ teaser photo seems to point in that direction as well.
