Rumor: Marvel Studios Wants Narcos Star To Play Mister Sinister In X-Men Reboot

Marvel Studios may be closing in on an actor to play Mister Sinister in the upcoming X-Men reboot, and if a new rumour is to be believed, Civil War star Wagner Moura is the frontrunner.

We've been hearing rumblings for a while that Jake Schreier's upcoming X-Men reboot will feature Mister Sinister, and it seems Marvel Studios is zeroing in on an actor to play the fan-favourite villain.

According to insider @MyTimeToShineH, Narcos star Wagner Moura is the "top choice" to take on the role in the MCU. Best known for playing drug trafficker Pablo Escobar in the Netflix crime series, he also counts SergioPuss in Boots: The Last Wish, Civil War, and The Secret Agent among his many credits. 

Marvel Studios clearly has a "type" in mind for Sinister, as Javier Bardem was previously reported to be in the running. When 20th Century Fox was still in charge of the X-Men, Mad Men star Jon Hamm was expected to make his debut as the villain in The New Mutants. However, in the wake of the Disney/Fox merger, the idea was scrapped, and his post-credits cameo was never shot.

While nothing is confirmed at this stage, it's hard to find fault with Moura potentially playing Mister Sinister. He's quickly becoming an in-demand talent in Hollywood, and seems a fitting choice to bring the Summers-obsessed baddie to the big screen.

Mister Sinister is expected to serve as the X-Men franchise's big bad in the MCU's next Saga, meaning we'll likely see him in more than just one movie. However, we're sure you'll remember reports that the endgame is reportedly an Avengers vs. X-Men movie. 

In the comics, Nathaniel Essex is a brilliant but twisted geneticist and supervillain, obsessed with genetic manipulation and the perfect mutant gene, often experimenting on Cyclops and Jean Grey due to his fascination with the Summers bloodline. Created by Chris Claremont and Marc Silvestri, he first appeared in Uncanny X-Men #221 in 1987.

Marvel Studios has been sitting on the rights to the X-Men for the better part of six years, but after critical and commercial flops like Dark Phoenix and The New Mutants, putting the characters on ice for a while was a must.

In the meantime, access to Earth-10005 has proved an easy way to add mutants to the Multiverse Saga, in titles like Deadpool & Wolverine and the upcoming Avengers: Doomsday

X-Men doesn't have a release date, but is rumoured to begin shooting this year for a 2028 debut.

He’s a great actor, he could pull it off

@Mandalorian47 - "Moura has stated that he was asked by industry professionals to adopt a "standard American accent" for roles, but he refused, arguing that his natural Brazilian accent is part of his artistic identity. He believes that international actors should not dilute themselves to assimilate, noting that "the more I bring Brazil with me, the more interesting I am as an artist."

@Ryguy88 - Essex is British so that would be a big change.

@Ryguy88 - he is famous for playing a Colombian.

@CreateNowSlpL8r - maybe they will make him a Victorian era Spainard?
Ryguy88
Ryguy88 - 7/9/2026, 8:41 AM
@LeDiableBlanc - yeah, apparently he only wants to stick to his Latin American accent...because hes never heard of "acting" before.

Feels more like Shaw than Essex. Get him regardless.

@MCUKnight11 - was gonna say the same thing.

Josh Harnett looks more like Sinister than Wagner.
TheVisionary25
TheVisionary25 - 7/8/2026, 5:42 PM
@MCUKnight11 - I could see that too

However there’s a rumor that Patrick Wilson is up for a role in the film and I could see him as Sebastian Shaw too.

@gambgel - Yes, and I know he can play all facets of Sinister too. I mean Moura could do it I guess...I just don't see it yet.

@dragon316 - That's fair...to me, only Johnny and The Thing are the ones I'm ok with. I like Pedro and Vanessa, I'm just indifferent about their castings. Seems like they would have been better served elsewhere.

@thedrudo - It’s even in the article but I have read more than one person say that they skip Josh’s articles and come straight to the comments.

Honestly , I kinda like this tbh if true…

Moura can be charismatic and menacing imo such as his voiceover portrayal of Death in “Puss in Boots:The Last Wish”.

?feature=shared

The only thing I can see some having issue with is that he has a thick Brazilian accent while Mr Sinister is from Victorian London in the comics but they can always revise/reimagine that backstory to an extent so not a big deal for me atleast.

Anyway , I hope we start getting official casting news for the MCU X-Men soon!!.

@TheVisionary25 - I'll never complain about Wagner Moura in anything; the dude is a phenomenal actor and can play almost anything. Honestly, he was my pick for the Academy Award this year.
Kiba
Kiba - 7/8/2026, 6:06 PM
He was fantastic in Narcos but I just don't see it. Then again, I predict a lot of ridiculous reimagining for the MCU X-Men. Erik Lehnsherr will either be Erik Al-Najjar or Erik Nwachukwu. I have no faith in Disney whatsoever to do this right.
MarvelZombie616

@Kiba - Yeah, countdown me out if they race-swap a single X-Men character.
The X-Men are as diverse as they come.

Bardem should’ve been Doom. Maybe Apocalypse down the road.
EscapeMySight
EscapeMySight - 7/8/2026, 6:28 PM
@soberchimera - I always loved the idea of Mads Mikkelsen as Doom.
Kiba
Kiba - 7/8/2026, 6:34 PM
@EscapeMySight - The MCU never came close to using Mads Mikkelsen to his full potential.
Fogs
Fogs - 7/8/2026, 6:54 PM
@EscapeMySight @Kiba - I'll never get over the fact they didn't retcon Kaecilius as Victor. Mads should've been Doom, hands down.
EscapeMySight
EscapeMySight - 7/8/2026, 6:54 PM
@Kiba - Completely agree. Wasted potential.
RolandD
RolandD - 7/8/2026, 8:40 PM
@Fogs - Already has a built in accent that at least is not American.

@soberchimera - Anyone would have been better than the gimmicky casting of RDJ. I hate that they did that so much.
Fogs
Fogs - 7/9/2026, 4:48 AM
@Toecutter - Just think about it. He comes back from the dark dimension. He's all deformed and wants vengeance. Then it's revealed he sought magic to save his mother from hell. DS4 should adapt Triumph and Torment.

@EscapeMySight - Doom needs to be someone who can be more bombastic

Would be a great choice. Elite Squad put me on to just how good an actor he is.

Great choice. Unexpected and not who I'd think of for this role, but I like it! Bring it on.

So, are they going to cast a Brazilian actor to play an Englishman? What's next? Are they going to cast a Norwegian to play Sunfire? 🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️
Fogs
Fogs - 7/8/2026, 6:55 PM
@hsanjose - Anyone can be a brazilian, so...
EskimoJ
EskimoJ - 7/8/2026, 7:34 PM
@hsanjose - How about an Australian to play a Canadian?
ImNotaBot
ImNotaBot - 7/9/2026, 12:37 AM
@hsanjose - American and British actors play characters of different nationalities all the time. Just look at The Odyssey there isn’t a single Greek actor in the main cast. Why shouldn’t talented actors from other countries be given the same opportunity?
ImNotaBot
ImNotaBot - 7/9/2026, 12:44 AM
@hsanjose - Also, about 90% of Russian, French, South African, Brazilian, Italian, Egyptian, and countless other characters have been played by American and British actors since the birth of Hollywood, and no one seems to care.
Toecutter
Toecutter - 7/9/2026, 4:03 AM
@hsanjose - Absolutely none of the rumored actors, like Josh Harnett, Javier Bardem, or Jon Hamm, are English (I doubt any of them can even pull off an English accent; search up Josh Harnett's awful attempt at one), so who cares at this point, really. They probably won't even portray him as English.

Wouldn’t hate this at all. Phenomenal actor
CreateNowSlpL8r
CreateNowSlpL8r - 7/8/2026, 9:47 PM
eh, I dont see it. It also depends on which Sinister they are using. I prefer the classic Sinister as opposed to the goofy, over excentric version from the Krakoa error. He used to be genually terrifying but they watered him down with too much clone nonsense and personality changes.

Give me a chiesled brit to play him, make him terrifying.
