Let's be real for a second. Doctor Strange in the Multiverse of Madness left us with more questions than a philosophy major on a Sunday morning. That post-credits scene? Charlize Theron showing up as Clea, looking like she walked straight off a high-fashion runway into a cosmic rift? It changed everything. Now, everyone is buzzing about a Doctor Strange 3 fancast because, honestly, the stakes have never been higher for Stephen Strange. We aren't just looking at New York City anymore. We’re looking at the literal collapse of realities.
Incursions are coming.
If you’ve been following the Marvel Cinematic Universe since 2008, you know the drill. Fans love to play casting director. But this isn't just about picking someone who looks the part. It's about finding actors who can stand toe-to-toe with Benedict Cumberbatch’s specific brand of "arrogant but deeply traumatized surgeon." The third film needs to bridge the gap between the weirdness of Sam Raimi’s vision and the looming threat of Avengers: Secret Wars.
Why Clea Changes the Casting Game
Charlize Theron is already in the building. That’s a fact. But her arrival as Clea—the niece of Dormammu and Strange’s primary love interest in the comics—opens a massive door. We need a Dark Dimension that feels lived-in, not just a bunch of CGI purple clouds. To make that work, the Doctor Strange 3 fancast needs to focus on the royal family of the Dark Dimension.
Specifically, we need a Dormammu who is more than just a giant floating face. While Benedict Cumberbatch actually provided the motion capture and voice for Dormammu in the first film, many fans are clamoring for a humanoid version. Imagine Bill Nighy. Seriously. His ability to be both terrifying and strangely aristocratic would fit the vibe of a Dark Dimension ruler perfectly. Or maybe someone with the sheer physical presence of Javier Bardem. You need an actor who can convey "I own this hellscape" with a single look.
The Return of the Illuminati (But Different)
The 838 universe version of the Illuminati got absolutely shredded by Wanda. It was brutal. Honestly, it was a bit of a shock to see John Krasinski’s Reed Richards turned into blue spaghetti so quickly. But the multiverse is infinite. That’s the whole point, right?

A huge part of the Doctor Strange 3 fancast conversation centers on who will represent the "Council of Stranges" or a new Multiversal Illuminati.
- The Superior Iron Man: Fans have been begging for Tom Cruise to play a variant of Tony Stark for years. If Doctor Strange 3 dives into the fallout of the incursions, seeing an arrogant, Extremis-powered Stark played by Cruise would be the ultimate "what if" moment. It’s not just a meme anymore; it’s a narrative necessity to show how dangerous other universes can be.
- Brother Voodoo: We’ve already seen Daniel Drumm die in the first movie. In the comics, his brother Jericho Drumm becomes Brother Voodoo. For this role, the internet has largely settled on someone like Mustafa Shakir (from Luke Cage) or even John David Washington. You need someone with gravitas who can handle the mystical side of the MCU without feeling like a "Doctor Strange Lite."
- Nightmare: Rumors have swirled for years that Nightmare was supposed to be the villain of the second movie before the script shifted to the Scarlet Witch. If he shows up in the third installment, the fan favorite remains Eva Green. She has that ethereal, slightly spooky energy that fits the Dream Dimension perfectly. Alternatively, Bill Skarsgård—already a pro at playing nightmare fuel—would be an inspired, if somewhat obvious, choice.
The Problem with Mephisto and the "Troll" Castings
We have to talk about Mephisto. It’s basically a law of Marvel fandom at this point. Every time a shadow looks weird in a trailer, someone screams "Mephisto!" While Sacha Baron Cohen has been heavily rumored for a role in Ironheart that might be the devil himself, if he migrates to Doctor Strange 3, the dynamic shifts.
The Doctor Strange 3 fancast often gets bogged down in these "event" characters, but the best choices are often the ones that ground the sorcery. Think about the role of a mentor or a rival.
There is a growing movement to see Cillian Murphy in the MCU. While many want him for Doctor Doom, he would actually make an incredible, understated villain like D'Spayre. He doesn't need a giant laser beam. He just needs to talk. That's the kind of casting that makes a movie feel "human-quality" despite the capes and spells.
Breaking Down the "Strange" Variants
Benedict Cumberbatch is great, but seeing him play four different versions of himself in Multiverse of Madness was a lot. For the third film, if we encounter more variants, the fans are suggesting something radical: don't have Cumberbatch play all of them.

The multiverse allows for different faces. What if a variant of Stephen Strange was played by someone like Keanu Reeves? It sounds like fan-fiction, but Keanu has expressed interest in the MCU for years. His "Zen" energy would be a brilliant contrast to the high-strung 616 Strange we know and love.
Then there’s the "Sorcerer Supreme" version of Anthony Mackie’s Sam Wilson or even a variant of Mordo. Speaking of Mordo, Chiwetel Ejiofor is criminally underused. The Doctor Strange 3 fancast shouldn't just be about new people; it should be about better using the ones we have. We need a Mordo who is actually a threat, not just a guy who shows up to lose a fight and leave.
The Technical Reality of Casting the Third Film
Marvel casting isn't just about who is cool. It's about schedules. It’s about who can sign a six-movie deal and sit in a makeup chair for five hours.
When looking at the Doctor Strange 3 fancast, we have to consider the "Sam Raimi Factor" if he returns to direct. Raimi loves his frequent collaborators. Don't be surprised if Bruce Campbell gets a significantly larger role this time. Maybe as an actual mystical entity rather than a pizza ball vendor? That would be the most Raimi move possible.
Also, the budget for these films is astronomical. Disney is reportedly tightening the belt on some projects, but Doctor Strange is a pillar of the current "Multiverse Saga." They won't skimp on the antagonist. If the villain is someone like the Beyonder, expect a name that carries immense weight.

What the Fans Get Wrong About "Comic Accuracy"
A lot of people want a Doctor Strange 3 fancast that looks exactly like a 1970s Steve Ditko drawing. While the aesthetics are important, the MCU has succeeded because it prioritizes the vibe of the character over the exact haircut.
Take Clea. In the comics, she’s often portrayed as somewhat submissive to Strange early on. Charlize Theron isn't playing "submissive." She’s playing a powerhouse. The casting of the supporting characters needs to reflect that shift. We need a Wong (Benedict Wong) who continues his trajectory as the responsible "Dad" of the MCU, perhaps paired with a younger apprentice like Zelma Stanton.
For Zelma, someone like Thomasin McKenzie or Jenna Ortega would bring that "modern world meeting magic" energy that grounded the later Doctor Strange comic runs.
Actionable Insights for the Next Phase
If you’re following the development of the third film, keep your eyes on the trades (Variety, Hollywood Reporter) rather than just "leaker" Twitter accounts. The Doctor Strange 3 fancast is fun, but the actual production decisions will be driven by the path to Avengers: Secret Wars.
- Watch for Clea's back story: If Marvel casts a "Umar" (Clea’s mother), that’s a sign the movie will be a deep dive into Dark Dimension politics.
- Monitor the Doctor Doom news: If Doom is the big bad of the next Avengers, he will almost certainly cameo or be referenced in Strange's world, as they are historically linked in the "Triumph and Torment" storyline.
- Look for "Strange Academy" hints: If we see younger magical characters being cast, Marvel might be pivoting to a mentor role for Stephen, which changes the type of actors they’ll look for.
The next few months are going to be wild. With San Diego Comic-Con and D23 on the horizon, we’ll likely get a glimpse of which of these fan theories hold water. Whether it's Keanu as a variant or Eva Green as a nightmare, the goal remains the same: making the supernatural feel spectacular again.
Check the official Marvel production sheets as they leak to see which "working titles" are being used, as these often hint at the characters involved. For example, "Checkmate" or "Spiral" often point toward specific comic arcs that dictate which characters will actually appear in the final cut. Stay skeptical of "confirmed" lists that don't cite a primary source, and remember that in the multiverse, literally anything can happen.
