It’s been teased since the end of the first Avengers film five years ago, but the long-awaited battle between Marvel’s superheroes and Thanos is finally happening.

While Thanos (Josh Brolin) has made cameos in other Marvel superhero films before, this is the first movie where “The Mad Titan” is front and center—arriving on Earth to collect the powerful Infinity Stones. What follows can only be described as a massive confrontation between Thanos’ army and the entire Marvel universe.

Infinity War is the first half of the two-part finale to Marvel’s Phase 3 of films, with one more (currently untitled) Avengers film to arrive in 2019. This is the first Avengers film directed by the Russo brothers, who have been praised for their work on the last two Captain America films.

The film arrives in theaters May 4, 2018.
