Some people believe Iron Man 4 will be the next MCU movie to receive a release date because of a cryptic poster. For more than ten years, Marvel Studios’ adaptation of Robert Downey Jr.’s Tony Stark served as the cornerstone of the superhero genre and served as the inspiration for the eventual Marvel Cinematic Universe.

However, after three solo films and several team-up efforts, the character’s big-screen tenure seemingly ended with the death of Downey’s Marvel hero in Avengers: Endgame, indicating there would be no plans for any future Iron Man movies.
