Avengers: Doomsday Team On Bringing Robert Downey Jr. Back To The MCU - "We Can Do Whatever The Heck We Want"

Avengers: Doomsday directors Joe and Anthony Russo and Marvel Studios head Kevin Feige explain their decision to bring Robert Downey Jr. back to the MCU as a different character...

The first trailer for Avengers: Doomsday (we have seen several character-focused vignettes) debuted during CinemaCon this week, and while the footage was not released, detailed breakdowns have been doing the rounds online.

As expected, Robert Downey Jr.'s Doctor Doom was the main focus. In addition to showcasing the villain's comic-accurate costume in live-action, attendees got to see Doom easily block an attack from Thor, and hear him speak for the first time (RDJ was said to have used an Eastern European accent).

Doom is never shown without his mask, however, and rumor has it that he will not reveal his face to Earth's Mightiest Heroes at all in this movie.

Although the majority of fans now seem to be on board, the initial announcement that Downey Jr. would be returning to the MCU as an entirely different character after playing Tony Stark for so many years was met with a mixed response. While speaking with EW at CinemaCon, Kevin Feige explained how the idea originated.

"He is ingrained in the fabric of the MCU for obvious reasons, and we would talk about when and how and if there could be a return. At the time, [Downey] was on his way to winning the Academy Award for Oppenheimer and there was every story about 'the greatest actor in the world,' and we thought, 'This could be it. Let's do it.' It's our universe. It's a multiverse. We can do whatever the heck we want. He played the most iconic hero. Let's have him play the most iconic villain." 

Downey Jr. is believed to be playing the Victor Von Doom and not an evil Iron Man variant, but we may still get some kind of explanation as to why he so closely resembles Stark in Secret Wars.

As for Doom's insane power levels, co-director Anthony Russo reveals that the ruler of Latveria may have deep-seated vulnerabilities that can be exploited.

"Certainly with Doom, it's the problem in the extreme in that his power is so immense and so beyond. But that really liberates us all on a creative level, artistic level, to figure out where the complexities and the vulnerabilities are in the character," said the filmmaker. "They may have seemingly unlimited physical power, but there is something inside them where they are vulnerable, where they are exposed, where [there are] places that they need to protect even more intently than their physical selves. So I think the real fun of the storytelling is in that zone there."

If you've been keeping up with the rumors, you may have some idea what Russo is referring to here (it's the reason he targets Steve Rogers in the first place).

Aside from the title screen, nothing from the CinemaCon teaser has leaked, but there are a few fake screenshots doing the rounds that have fooled some people on social media. Honestly, they didn't even try with these!

Avengers: Doomsday and Avengers: Secret Wars were hit with significant delays last year, with Doomsday now set to arrive in theaters on December 18, 2026, and Secret Wars positioned for December 17, 2027.

Both movies will be directed by the Russo brothers, who also make their MCU return after helming Captain America: The Winter Soldier, Captain America: Civil War, Avengers: Infinity War and Avengers: Endgame

"Being able to create stories and explore characters within the Marvel Universe fulfilled a life-long dream of ours, and we discovered a powerful connection with audiences in each film that we made. We’re thrilled to collaborate once again with Kevin, Lou and the entire Marvel team to bring this epic adventure in storytelling to new and surprising places for both the fans and ourselves”, said The Russos in a statement after the SDCC panel.

Doomsday will star:

Paul Rudd as Ant-Man, Simu Liu as Shang-Chi, Tom Hiddleston as Loki, Lewis Pullman as Sentry, Florence Pugh as Yelena, Danny Ramirez as Falcon, Ian McKellen as Magneto, Sebastian Stan as Bucky, Winston Duke as M’Baku, Chris Hemsworth as Thor, Kelsey Grammer as Beast, James Marsden as Cyclops, Channing Tatum as Gambit, and Wyatt Russell as U.S. Agent

Along with Vanessa Kirby as Sue Storm, Rebecca Romijn as Mystique, Patrick Stewart as Professor X, Alan Cumming as Nightcrawler, Letitia Wright as Black Panther, Tenoch Huerta Mejia as Namor, Pedro Pascal as Reed Richards, Hannah John-Kamen as Ghost, Joseph Quinn as Johnny Storm, David Harbour as Red Guardian, Ebon Moss-Bachrach as The Thing, Anthony Mackie as Captain America, and, of course, Robert Downey Jr. as Doctor Doom.

‘It's our universe. It's a multiverse. We can do whatever the heck we want.’ Sounds like Kevin has lost the plot and now just on some massive ego trip. There is also another relevant saying here ‘you can lead a horse to water, but you can’t make it drink’. Disney/Marvel need to take the fans with them on their ideas and direction as without them their MCU is nothing. Cillian Murphy would have been a far better Doom.

@Spike101 - Fans' ideas are notoriously terrible and emotion-based.

Consider what they'll enjoy but definitely don't let them write the stories for you.

@Spike101 - Feige: "Also, we are bleeding money after so many years of bad decisions - we just butchered our entire VFX team - and pushing agenda-based characters we know the fans don't care about, but figured we'd force them to anyway." "So, it was really just a money-based decision that will pay off or bankrupt us again, because we know fans love RDJ." Yes, Cillian Murphy or Mads would have been incredible as Doom.

@Spike101 - dude, Cillian Murphy doesn't want to join some superheroes franchise. However if he changes his mind if someone give him a better script, well he might join Marvel or DC comics. I thought you guys hate Cillian because he is so thin not so muscular. Because Dr. Doom is also buff too even though he wearing a armored suit in the comics. You're totally love to hate everything don't you? Dude, stop hating for a while and judge it after you watch the film in December.

@Spike101 - if Marvel thinks fans are going to believe that Doom is not connected to Starks, given that they have the same face, then they’re fools. RDJ was brought back for a specific reason. Don’t believe their bullshit.
Spike101
Spike101 - 4/18/2026, 1:59 PM
@RyLondon50 - I can easily see there being a connection. I seem to remember in early interviews they did say the similarity would be explained in the movie so let’s see.

"But there is something inside them where they are vulnerable"

For some reason I now think they're gonna defeat him inside The Void. He'll probably want to The Sentry for his own benefit, but they could blow back on him I guess.

Good lord. Those leaked scenes scream a lot of green screen and actors pasted together or acting by themselves 😭

"We Can Do Whatever The Heck We Want" except finish a script on time, plan ahead entirely, and try to abstain from Nostalgia ad nauseum.



Having said that... HAPPY SUPERMAN DAY! I'm sure there will be plenty of articles and content today right?

Anywho, happy Superman Day!!!

Hollywood is always doing the friends and family thing, but when it comes to telling one long story, keep it fresh. Usually that requires different voices, fresh faces, and new energy.

Then again, it’s RDJ. He rarely misses.
TheVisionary25
TheVisionary25 - 4/18/2026, 8:56 AM
@ElJefe - I agree.

I would rather have had new blood & voices in the film rather then having the Russo’s back at the helm or RDJ as Doom…

But the brothers have arguably made 4 of the best MCU films so far and RDJ is great actor with range who as you said , rarely misses so it’s definitely mixed feelings.
ElJefe
ElJefe - 4/18/2026, 2:17 PM
@TheVisionary25 - And he’s playing perhaps the most iconic Marvel villain in the roster. If they don’t nail this one it’s gonna get ugly.

Retread, rehash, recycled, redone, retrashable, it's all the same shit.

Marvel is too scared to do anything new because they know that they would fail miserably. So they revert back to what works which is nostalgia and cramming as many characters in one movie.

Eventually people will get tired of their bullshit and stop watching.

Them bringing back this former druggie saved them from another flop.

As always, I will spoil the whole movie a week before it comes out just because I like you all. Same thing for BND, it will be spoiled to you all for no apparent reason.

@EskimoJ - It's funny, isn't it -- the hate-watchers not realizing that hate-watching is still watching. They can gripe and they can complain, but they're still buying the movie tickets, they're still renting or buying on streaming -- they are still coughing up good money to watch something they have no intention of liking.

That's just stupid. There is no other word for it. Just pure, plain old stupid.

@Nolanite - I'm not understanding this take at all. The movie is a big event story just like the comics so of course there would be a lot of characters. Not for nostalgia but because they are all a part of the story. Multiple universes dieing is going to affect Multiple characters from multiple universes. In my opinion it really should include others such as the defenders, moon knight and many characters we have yet to see on screen as yet if that was even possible.

If you aren't watching "anything Feige or the mouse"... how the [frick] can you spoil it???
