Marvel has just announced that Christopher Markus & Stephen McFeely will once again team up with the Russo brother for the two-part climax to Phase 3 of the MCU.

The writing duo behind “Captain America: The First Avenger,” “Captain America: The Winter Soldier,” and “Captain America: Civil War” will write the screenplays for “Avengers: Infinity War – Part 1” and “Avengers: Infinity War – Part 2.”

Producer Kevin Feige had this to say in a statment:

“Chris and Steve have been an integral part of the Marvel family since the early days of Phase 1, and their work speaks for itself. We couldn’t be more excited to have them with us to help guide the Avengers through their biggest story yet.”

In addition to writing all three films in Marvel’s Captain America franchise, Markus & McFeely also created “Marvel’s Agent Carter,” which premiered earlier this year on ABC, and co-wrote Marvel’s “Thor: The Dark World.” Beyond their work for Marvel, Markus and McFeely also wrote “Pain & Gain,” “You Kill Me,” and “The Life and Death of Peter Sellers.”

“Avengers: Infinity War – Part 1” hits theaters on May 4th, 2018 and Part 2 hits theaters on May 3, 2019.
