Doomsday’ Star Confirms Scenes With Robert Downey Jr.’s Doctor Doom [Exclusive]

The jokes people make about the Marvel Studios snipers whenever spoilers get too close to being revealed have gone around for years, with the studio preferring to focus on what they let go public. As such, Robert Downey Jr.’s return to the MCU as Victor Von Doom has remained one of Avengers: Doomsday‘s greatest mysteries. While the trailers have teased how perilous he is, we don’t actually know how bad this Latverian truly is. Even the actors sharing the screen with him have been reluctant to say much.

During an interview with Collider’s Steve Weintraub at San Diego Comic-Con following Marvel’s Hall H presentation, Hayley Atwell offered one of the clearest descriptions yet of what it was like working opposite Downey’s Doctor Doom, admitting his performance fundamentally changed the atmosphere on set. Asked how much she wanted to learn about Doctor Doom while filming, Atwell admitted she deliberately avoided asking questions because Downey’s performance spoke for itself, and explained that the contrast between Downey on and off camera made the experience even more striking. She told Collider:

“I didn’t ask, in part because his presence on set was so enigmatic as Doom. Robert, in between takes, he invites people to eat lunch with him, and he’s super open and fun and wants everyone to have a good time… But when he’s Doom, it’s so enigmatic. It’s so domineering that it’s really intimidating and very powerful.”

Rather than breaking that illusion, Atwell wanted to preserve it throughout filming, so that the feeling of dread, menace and uncertainty was rampant throughout her performance. It’s one of the most revealing descriptions yet of Downey’s take on Marvel’s iconic villain. “Also, when I was in scenes, I didn’t want that illusion to be broken for me,” Atwell explained, “so I kept that feeling of, ‘I don’t know who this person really is and what they’re capable of, but I just know there’s a darkness there.’”

How do you lead when the stakes couldn’t be higher?
The way you lead under pressure is the most candid thing about you.

AI absorb everything — every variable, every pattern — and move only when I know the path forward.
BI read the room, make the call, and own the consequences. Hesitation costs more than mistakes.
CI rally people. A cause needs a voice, and I refuse to let fear be louder than conviction.
DI assess the threat, establish what needs doing, and get it done without waiting for permission.
EI don’t lead. I act. Others can follow or not — I’m already moving.

02

What is your greatest strength in a crisis?
The quality that keeps you alive when everything else fails.

APrescience — the ability to see further ahead than anyone else and plan accordingly.
BImprovisation — I’m at my best when the plan falls apart and I have to invent a fresh one.
CConviction — I know what I’m fighting for, and that certainty doesn’t waver under fire.
DComposure — I stay functional when everyone around me is falling apart. Panic is a luxury.

BThe safety of my crew — every single one of them. No one gets left behind.
CFreedom — for my people, for every world still crushed under the weight of an empire.
DThe truth — what actually happened, what’s actually out there, whether anyone believes me or not.
EThe one person — or the one memory — that still makes any of this worth surviving for.

04

How do you relate to the people around you?
Who you are to others under pressure is who you really are.

AWith intensity and distance — I care deeply, but the weight I carry makes closeness complicated.
BWith warmth and irreverence — I take the mission seriously, not myself.
CWith directness and trust — I say what I mean, and I expect the people I work with to rise to it.
DWith professional care but clear limits — I’ll protect you, but I won’t pretend we’re family.
EWith wariness that slowly becomes loyalty — I don’t trust easily, but when I do, it holds.

05

You’re facing a threat that no one else believes is real. What do you do?
How you respond when you’re the only one who sees it defines everything.

APrepare in silence. If they won’t listen, I’ll be ready when they finally have to.
BKeep pushing until someone listens — and if no one does, handle it myself.
CBuild the case, find the allies, and make the threat impossible to ignore.
DDocument everything. The truth matters even if no one believes it yet.
EStop trying to convince anyone. Survive it. That’s the only argument that counts.

06

What has your heroism cost you personally?
Every hero pays. The question is what — and whether they’d pay it again.

AMy innocence — I’ve seen what I’m capable of, and I can’t unsee it.
BPeople I loved — the command chair has a view, but it’s a lonely one.
CA normal life — I gave up everything ordinary the moment I chose the cause.
DMy sense of safety — I know exactly what’s out there now, and I can’t pretend otherwise.
EAlmost everything — and I’m still not sure what I’m carrying it all for. But I keep going.

How do you feel about the rules of the world you’re in?
Every hero has a relationship with the system. What’s yours?

AI understand them deeply — and I know exactly which ones must be broken, and why.
BI respect the spirit of them and bend the letter when the situation demands it.
CThe system is the problem. I’m not here to work within it — I’m here to dismantle it.
DI follow protocol until protocol stops being useful. Then I make the call myself.
EThe rules collapsed a long time ago. What’s left is instinct, and mine are reliable.

08

When everything is on the line, what keeps you going?
The answer is the most candid thing about you.

ADestiny — or something that feels so much like it that the difference no longer matters.
BThe people on my ship — their faces, their trust, the fact that they’re counting on me.
CThe belief that what we’re fighting for is worth every sacrifice, including this one.
DSheer refusal to let it win — whatever it is. I don’t stop. That’s just who I am.
EI’m not sure anymore. But the road is still there, and I’m still on it.

Your Hero Has Been Identified
Your Sci-Fi Hero Is…

Your answers point to the iconic sci-fi hero who shares your instincts, your values, and your particular way of facing the impossible.

Arrakis · Dune

Paul Atreides

You carry a weight most people would crumble under — the knowledge of what you’re capable of, and the burden of what you might have to become.

• You see further ahead than others and you plan accordingly, even when the vision frightens you.
• You are driven by loyalty to your people and a sense of destiny you didn’t ask for but can’t escape.
• Paul Atreides is not simply a hero — he is someone who understands the cost of power and chooses to bear it anyway.
• That gravity, that willingness to carry what others won’t, is exactly you.

USS Enterprise · Star Trek

Captain Kirk

You lead with instinct, warmth, and an absolute refusal to accept a no-win scenario — because you’ve always believed there’s a third option nobody else has thought of yet.

• You take the mission seriously without ever taking yourself too seriously.
• Your crew would follow you anywhere, not because you demand it, but because you’ve earned it.
• Kirk’s genius isn’t tactical — it’s human. He reads people, bends rules with purpose, and wills outcomes into existence through sheer conviction.
• That combination of warmth, audacity, and relentless optimism is unmistakably yours.

The Rebellion · Star Wars

Princess Leia

You are the kind of person who holds the line when everyone else is losing faith — not because you’re fearless, but because giving up simply isn’t something you’re capable of.

• You lead through conviction. Your voice carries because your belief is unshakeable.
• You gave up everything ordinary the moment you chose the cause, and you’ve never looked back.
• Leia is not a supporting character in her own story — she is the moral centre of the entire rebellion.
• That same fierce, principled, unbreakable core is what defines you.

The Nostromo · Alien

Ellen Ripley

You are not reckless, not grandiose, and not particularly interested in being anyone’s hero — you just refuse to stop when it matters.

• You see threats clearly, you document the truth even when no one listens, and when the time comes you handle it yourself.
• Ripley’s heroism is earned, not performed. She doesn’t have a speech — she has a flamethrower and a plan.
• You share her composure under the worst possible pressure, and her refusal to pretend the monster isn’t there.
• When it counts, you don’t flinch. That’s everything.

The Wasteland · Mad Max

Max Rockatansky

You have been through fire that would break most people — and what came out the other side is something the world underestimates at its peril.

• You don’t ask for facilitate, don’t need validation, and don’t wait for anyone to tell you the rules no longer apply.
• Your loyalty, when it finally arrives, is absolute — but it’s earned in silence and tested in action, not in words.
• Max is not a nihilist. He is someone who lost everything and found, against his will, that he still has something worth protecting.
• That bruised, stubborn, ultimately human core is exactly yours.

Marvel Is Introducing Doctor Doom as a Completely New Character

Marvel Studios president Kevin Feige also addressed Doctor Doom during Comic-Con, explaining that Avengers: Doomsday has been designed as a true introduction to the character rather than relying on audiences’ knowledge of the comics. Comparing Doom to villains such as Green Goblin, Doctor Octopus and Thanos, Feige explained that every great Marvel antagonist has to work for newcomers first. “This is a movie that introduces Doctor Doom to the world, and peels the onion on a fascinating, fascinating character,” said Feige. The Russo Brothers echoed that sentiment, describing Doom as “the smartest man in every room he walks into” whose mastery of both science and the Dark Arts makes him unlike any villain the MCU has faced before.

Avengers: Doomsday arrives in cinemas on December 16, 2026.
