Robert Downey Jr. will officially return to the Marvel Cinematic Universe as the villainous Doctor Doom in the upcoming "Avengers: Doomsday." But rumors continue to suggest Doom may not be the only role he plays in his MCU comeback. On a recent episode of "The Hot Mic," entertainment insider Jeff Sneider suggested Downey could eventually suit up as Iron Man once again.

Sneider first addressed recent reports that "Predator: Badlands" director Dan Trachtenberg is in talks to direct a MARVEL movie. While some speculation has pointed to a new solo "Wolverine" or "Blade" film, Sneider said he did not believe either project was Trachtenberg's target. Instead, he speculated that the mystery movie could be "Iron Man 4."

Sneider also predicted that Downey could reappear as Iron Man in another project before starring in "Iron Man 4." He pointed to the next Avengers sequel, "Avengers: Secret Wars," as the most likely place for Tony Stark's return.

This is not the first rumor linking Downey's Iron Man to "Secret Wars." Several purported script leaks have claimed that Downey could play both Doctor Doom and a disillusioned alternate-universe version of Tony Stark, who would help the other heroes fight back against Doom's rule over the multiverse. If Sneider's prediction proves accurate, his comments may be referring to that same rumored storyline.
