Avengers: Doomsday represents a major shift in direction for the Marvel Cinematic Universe following the abandonment of the Kang the Conqueror story arc. A new report claims directors Joe and Anthony Russo went all out to aid that shift by completely revamping the original screenplay for the anticipated sequel.

The Russo brothers were not keen on returning for another Avengers movie. However, things changed soon. Read on to learn how.

Reunited on the forthcoming Marvel films with screenwriter Steven McFeely — one half of the partnership of Markus and McFeely, who scripted all the prior Russo Brothers Marvel films— Joe Russo, in this week’s profile, recalls calling the latter with a “crazy idea.”

In an interview alongside Joe Russo and screenwriter Steven McFeely with Empire, Anthony Russo explained, “ Endgame was the end, and it took a little time for us to begin to think about it as something other than an end.

Secret Wars, Marvel shifted to Avengers: Doomsday and Avengers: Secret Wars. They still focus on a multiversal war leading to a confrontation between the Avengers and a big villain, but Marvel delivered an incredible twist.
