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.

Feels more like Shaw than Essex. Get him regardless.

@MCUKnight11 - was gonna say the same thing.

Josh Harnett looks more like Sinister than Wagner.

@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.

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!!.

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.

Bardem should’ve been Doom. Maybe Apocalypse down the road.

@soberchimera - I always loved the idea of Mads Mikkelsen as Doom.

@EscapeMySight - The MCU never came close to using Mads Mikkelsen to his full potential.

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.
