It is the second part of Avengers: Infinity War which was released exactly a year before, on April 26, 2018. It's been a long time coming, but we finally have a name for the film and the first official trailer. With many of the our favourite heroes existence left in question. However the trailer does show a small cast of heroes including Iron Man, ... and one of the most interesting is Ant-Man turning up after being presumed dead - he was left stranded in the Quantum Realm at the end of his last movie . The Ant-Man films leans heavily on the Quantum Realm - the subatomic universe that exists between particles - and given that Ant-Man was conspicuously missing from Infinity War, it's very possible that Ant-Man's biggest secret could hold the power to bring back the Avengers, and, well, 50 percent of the universe.
