Robert Downey Jr.’s Iron Man makes his Marvel Cinematic Universe return in a Spider-Man 4 theory, and if it turns out to be accurate, Marvel Studios would have one of the franchise’s most emotional projects on its hands. Marvel’s slate of projects includes several exciting movies and series, with entries like The Fantastic Four, the next two Avengers movies, and Spider-Man 4 drawing the most attention. Given how Tom Holland’s first MCU Spider-Man trilogy is among the franchise’s best, it makes sense that anticipation is high for the return of his version of Peter Parker.
