Directed by the Russo Brothers, the creative team behind the iconic “Infinity War” and “Endgame,” “Avengers: Doomsday” promises a return to the cohesive storytelling that fans have longed for. The script, penned by Steven McFeely, is expected to delve deeper into the concept of incursions—events where universes collide, posing an existential threat. This theme has been teased in previous projects such as “Loki” and “Doctor Strange in the Multiverse of Madness,” setting the stage for a potential multiversal war.
