Chris Evans shared that Marvel Studios frequently approached him with offers to return to the role of Steve Rogers after the premiere of Avengers: Endgame. The actor stated that over the past eight years, he had been presented with about a dozen different story ideas, but none of them convinced him.
Immediately after the conclusion of Endgame, Marvel Studios president Kevin Feige and producer Lou D'Esposito considered continuing the Steve Rogers arc through his comic book alter ego, Nomad. However, Evans agreed, wanting to maintain continuity and provide a fitting conclusion to his character's story.
The turning point came when Evans learned of Roberta Downey Jr.'s potential return to the Marvel Cinematic Universe. After speaking with director Joe Russo and learning the concept for Avengers: Doomsday, the actor felt that this project represented a significant opportunity to reprise his role as Steve Rogers.
In conclusion, Evans noted that he doesn't rule out future appearances by Captain America, but is only willing to return if there's a truly powerful and compelling storyline that doesn't devalue the legacy his character has already built.
