The Russo Brothers say it was Kevin Feige who pitched Robert Downey Jr.'s Doctor Doom appearance - but they didn't say yes until they had the right story.
"That was Kevin [Feige]. And interestingly enough about that is that conversation was had a while ago. Robert [Downey Jr.] tried to talk us into doing it and we said, 'No' ... We just didn't have a story," Joe Russo told Omelette (via Newsweek). "We didn't have a way in, right? We were resistant for a while. And then one day ["Avengers: Endgame" writer] Steve McFeely, who's one of our key collaborators, said, 'I have an idea.' And he called us in pit and we said 'That's the story. That story has to be told. It's a really powerful story.'"
