Since November, we have heard that Avengers 3 and 4 could, or would, be directed by the Russo Brothers and now Badass Digest says the deal has been finalized.
Anthony and Joe Russo got into Marvel's good graces with their first feature film Captain America: The Winter Soldier and next they will tackle the follow up Captain America: Civil War. After that, they have the honor of replacing Joss Whedon at the helm of The Avengers franchise. Badass Digest says they'll shoot Avengers: Infinity War Part 1 and Part 2 back-to-back in 2016 and 2017.
What's more, I keep getting told that Civil War is instrumental in setting up infinity War, so it's great that the Russos will be able to bring their story all the way through to the end.
Avengers: Infinity War Part 1 will arrive in theaters May 4th 2018 and then Avengers: Infinity War Part 2 will arrive May 3rd 2019.
