Overview
- Jon Favreau said on Jimmy Kimmel Live! that he phoned directors Joe and Anthony Russo to try to stop the decision about Tony Stark's final fate, and he later acknowledged he was wrong to oppose their execution of the scene.
- David Maisel, a Marvel Studios co‑founder, told The New Yorker that the studio board initially opposed casting Robert Downey Jr. because of concerns about his past drug problems and that Favreau ultimately pushed for Downey over Timothy Olyphant.
- Robert Downey Jr. played Tony Stark in ten MCU films from 2008 through 2019 and his performance is widely credited with anchoring the franchise's early tone and commercial rise.
- Multiple outlets report that Downey is set to return to the Marvel Universe in a new role, with reports saying he will portray Doctor Doom in Avengers: Doomsday on December 16, 2026, a detail described as reported rather than confirmed by Marvel.
- The new disclosures underline two longer‑term trends in the MCU: a willingness to accept early casting risks that paid off commercially and a continuing strategy of reusing legacy stars in fresh roles, a shift that could shape future storytelling choices.
