Prominent filmmakers Joe and Anthony Russo will direct parts 1 and 2 of the highly anticipated Avengers: Infinity War. News that the brothers are set to direct these two Marvel Entertainment pictures is not surprising considering they are also directing the studio’s Captain America: Civil War, which, like the films in the Avengers franchise, is noted for the large number of superheroes in the cast. The Russos previously directed last year’s blockbuster Captain America: The Winter Soldier, which grossed a staggering $717.7 million at the box office worldwide.

Based on the comic books by Jack Kirby and Jim Starlin, the screenplay was written by Captain America franchise writers Christopher Markus and Stephen McFeely.

Few details have been revealed about the storyline of Infinity War, but it’s clear that the focus will be the emerging villain Thanos, who was teased in Guardians of the Galaxy. Josh Brolin, who voiced the character, will reprise the role. Thanos’s goal is to collect all six of the Infinity Stones so he can acquire limitless power.

According to Cinema Blend: “We’ve seen that each individual stone is powerful on [its] own, but with all of them together, the Marvel heroes will face their greatest challenge yet. It isn’t just the Earth at stake when Thanos joins these ancient artifacts; it’s all of existence!” We can expect the heroes to join forces in the fight against this extremely powerful villain, because it won’t be easy to take him down.

The Avengers: Infinity War movies will both be filmed during one long shoot beginning sometime in 2016. Part 1 will be released May 4, 2018, and Part 2 is scheduled to hit theaters almost exactly one year later.
