So far we have yet to see him in action, but when Marvel announced Avengers: Infinity War Part 1 and Part 2 as part of their Phase Three slate in late 2014, the countdown officially began for when the MCU heroes will finally battle the Mad Titan.
We’ll have to wait and see what the new Avengers: Infinity War titles will end up being, but for now, Part 1 hits theaters on May 4, 2018, and Part 2 will follow on May 3, 2019.
So rather than Avengers: Infinity War being one gigantic story being told across two movies, they’re actually two different “entities” that are simply coming out a year apart.
Ever since The Avengers came out in 2012, the Marvel Cinematic Universe has been teasing Thanos as its overarching threat.
