Jon Favreau admits he was "wrong" in his resistance to killing off Robert Downey Jr's Tony Stark in the Marvel Cinematic Universe (MCU).
The 59-year-old filmmaker launched the franchise with 2008's Iron Man and has been involved with multiple movies since then, and he has recalled how he called Anthony and Joe Russo to object to their ideas for 2019's Avengers: Endgame, but he ultimately thinks the siblings did a great job with the film.
