Will Robert Downey Jr.'s Doctor Doom Unmask In AVENGERS: DOOMSDAY? New Rumor Offers Possible Answer

Following conflicting reports about what the deal is with Iron Man actor Robert Downey Jr. playing the MCU's Doctor Doom in Avengers: Doomsday, a new rumour addresses his possible unmasking.

One of the biggest unanswered questions from the recent Avengers: Doomsday plot leak was whether Robert Downey Jr. playing Doctor Doom will be part of the movie's story.

The Oscar-winner spent the better part of a decade suiting up as the MCU's Iron Man, and while over seven years will have passed since Tony Stark died in Avengers: Endgame when Doomsday arrives in theaters, the casting still feels intentional. 

After all, Downey and Iron Man were always a major selling point for movies like The Avengers, Captain America: Civil War, and even Spider-Man: Homecoming. With that in mind, will Marvel Studios really keep his face hidden beneath a mask?

John Campea chimed in while discussing the speculation about how a potential Spider-Man: Brand New Day post-credits scene could set the stage for the next Avengers movie. 

"One of the rumors about Doomsday that we did confirm for people is that they do not reveal Robert Downey Jr.'s face as Doctor Doom," he shared. "[I] want to make sure I'm careful about what I say after that."

"Just generally speaking, they don't reveal Tony Stark's face or Robert Downey Jr.'s face in Doomsday, and that the repercussions of that and the reasons for that and all that kind of stuff is something they're saving for Secret Wars," Campea added.

So, it may not be a plot point in Avengers: Doomsday, but it is something that Marvel Studios intends to explore in Secret Wars. If Victor Von Doom uses Loki's stolen power to create a new reality, perhaps he'll also give himself the face of Earth-616's greatest hero, even if it's just to mock those from the reality that helped cause Earth-828's destruction (via Steve Rogers).

While not new information if you read that recent leak, @MyTimeToShineH is reporting, "Yes, it's true Doom kills Steve's son in front of him in one of the most shocking moments in [Avengers: Doomsday]."

Let us know your thoughts on this latest Doom rumour in the comments section.

Avengers: Doomsday officially stars Chris Evans, Chris Hemsworth, Anthony Mackie, Winston Duke, Tom Hiddleston, Sebastian Stan, Letitia Wright, Paul Rudd, and Robert Downey Jr. Wyatt Russell, Simu Liu, Tenoch Huerta Mejia, Mabel Cadena, Florence Pugh, Danny Ramirez, David Harbour, Hannah John-Kamen, Lewis Pullman, and India Rose Hemsworth all make their Avengers franchise debuts.

The Fantastic Four: First Steps leads Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach, and Joseph Quinn join them, as do X-Men franchise stars Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, James Marsden, with Deadpool & Wolverine star Channing Tatum. The trades have pointed to Ryan Reynolds and Hayley Atwell also appearing in Avengers: Doomsday.

The Russo Brothers direct Avengers: Doomsday and Avengers: Secret Wars from a screenplay by Stephen McFeely, with whom they previously collaborated on the Avengers and Captain America franchises. Loki and Doctor Strange in the Multiverse of Madness's Michael Waldron has also been enlisted to help.

Avengers: Doomsday is set to be released on December 18, with Avengers: Secret Wars scheduled to arrive on December 17, 2027.

There's no way they're NOT showing his face after spending so much money to get him back. They also cant afford to save it for Secret Wars, thry need to grab the audience now if they want to see a return on their investment.

Though it would be pretty safe to assume we'd get a RDJ variant of Tony, so that could be their way around that if said variant or variants have a pretty substantial role.. but they didn't pay him so much money to keep his face covered for all of screen time.

@UnderBelly - depends on the money. I hear RDJ's voice cost a pretty penny.
Which, joke's on him! The U. S. doesn't make pennies anymore 😄

@UnderBelly - Dr Doom’s mask is a vital component of the character’s presentation. You could almost argue it’s his defining trait. Stories rely on a mystery to advance the stakes, adding depth. Acting is versatile you don’t need to illustrate every type of characteristic or emotion just to play a role. Not revealing the mask will keep audiences hooked, Robert will play the role with conviction without revealing his face. Actors, performers, are masters of deception, aura, confidence, emotions. The audience isn’t stupid. The filmmakers will make sure everyone knows that Downey is under the mask, his voice is enough to lean on. His eyes will keep you engaged. His reactions will be dramatic. It’s all good. With secret wars the mask reveal is paid off effectively, doomsday is the setup.

So's Iron Man's Helmet, so's Captain America's mask/Helmet, but keeping those money makers covered doesn't help with the marketing.

The fact that they announced RDJ'S return to play the villian means they WANT people to come and see him.. the same way they're showing Pedro's face again for the Mando movie...you better know they intend to get good on their investment.

Show a little ankle, then show a little leg. Save the holiest of holies for the end.

As big a star RDJ is, I doubt he stays masked up for the whole movie. Especially after the huge payday they spent to bring him back in as one of the most popular Marvel villains ever.

Ooh.... "Will he or won't be?"

It's like a great way to have soapbox drama in a sci-fi, action, fantastical Superhero movie.

Let me reach for the popcorn. And the Whiskey. And the extra-strength Tylenol for the morning. And bail money after getting arrested for public intoxication in a movie theater. And peeing on the Supergirl poster in revenge for Krypto's peeing on a Superman article.

I bet in second half of movie he reveal his face (maybe just someone not a group)

Honestly , the whole theory that he gives himself Tony’s face in order to mock the MCU heroes seems kinda dumb imo so I hope that’s not true…

Let’s just have it be simple as possible which is that like Chris Evans as both Johnny Storm & Steve Rogers , this version of Victor Von Doom just happens to look like 616’s Tony Stark without any complicated reasoning & such behind it.

However I could see them not revealing his face in Doomsday (atleast until the end with Steve) and really deal with that in Secret Wars if characters who had a close bond with Tony such as Peter ,Rhodey and Banner are in that since we can then see their reaction & emotional response to the reveal.

Anyway , I just really hope we get a good take on Dr Doom with a killer performance by RDJ as of now!!.
