When Marvel Studios or MCU announced that the next Avengers movies will be divided into two parts and it would close out the Phase 3 of the MCU, many were confused by the movie titles. The third Avengers film was given the title Avengers: Infinity War while the fourth film remained a secret. Many assumed that Infinity War would be a set-up for the next film.
Fortunately, it seems like that would not be the case. According to Marvel Studio head Kevin Feige, Infinity War and Avengers 4 will be entirely two different films. The Executive producer said this in an interview with IGN:
“There’s a reason we have publicly called the first one ‘Infinity War’ and the second one ‘Untitled,’ because the movies we were developing were not — certainly there’s a connection, there are with all our movies — but it’s not a first part and a second part. It’s a whole movie and a whole story, and then a whole movie and a whole story. That’s about all I can say. It’s certainly inspired by everything that has come before and everything that is hinted at before.”
Feige also discussed how he was looking forward to seeing how the superheroes would face up the Mad Titan King in Infinity War:
“We will be intercutting a lot of stories in that movie in a lot of different locales, as it sort of is in the Avengers movies as well; who is facing off against who. In this movie, it’s going to be fun to mix that up. One of the things that’s great about the Infinity Gauntlet is everybody tried to go up against Thanos whether they were god-like powers or not, because that’s what Avengers do. The fun about those two movies that we’re doing essentially at the same time is everybody’s there.”
