In just over a month Avengers Infinity War hits cinema screens, bringing together superheroes from the last 10 years of Marvel movies, across 18 films to date.

However this film is just part one of the spectacular finale, with the mysteriously untitled Avengers 4, concluding the first decade of movies in April 2019.

Speaking with ComicBook.com, Stephen McFeely said: “We know pretty much what's going on in Avengers 3. You've been told who's the bad guy and what he wants for several movies and it's not going to change: that's what's going to happen.

“You run it in the best possible way with twists along the way, but you have no idea what Avengers 4 is.”
