We know that a Fantastic Four MCU film is in development, but who should be cast to play one of Marvel's oldest characters? From the burning hot Johnny Storm to the stealthy Sue Richards, we've devised an MCU Fantastic Four fan cast, featuring some high-profile actors, along with some other lesser known ones who will fill the roles pe🌸rfectly. Our Fantastic Four are the adults of the MCU, so we've gone for a slightly older cast than some may expect. Here's our complete MCU Fantastic Four fan cast, and let us know who you'd swap out.

Jessica Lange as Agatha Harkness

Agatha Harkness may not be the first Fantastic Four supporting cast member thꦍat comes to mind when you think of the team, but in our minds, she's a bridge to the wider Marvel Cinematic Universe.

With connections to Doc♕tor Strange, Scarlet Witch, and more, Harkness is an FF confidante that widens Marvel's world of magic and the FF's sphere at the same time. And to play her, we've gotta suggest Jessica Lange.

Lange's made a genre rep in recent years as part of the American Horror Story ensemble cast, and we certainly envision her drawing on her role as Coven's "Supreme" wi🧸tch to play Harkness.

But even more than that, Lange possesses a timeless quality that makes 🐽her seem perfectly suited to any place or time - an ideal trait for a magical being. Lange's charm, wit, and alter🌳nating iciness and warmth (not to mention name recognition) make her the perfect choice to take on a prestige role that could bridge multiple films and franchises.

Ruth Wilson as Alicia Masters

Ruth Wilson's turn as the star-crossed Alison Bailey on Showtime's The Affair -𒅌 including her much-lauded death episode - more than prepared heℱr to portray Ben Grimm's long-time girlfriend-turned-wife.

In particular, during The Affair's first season, Wilson and co-star Dominic West played the same scenes twice in each episode with ✃two subtle but different takes - from her own POV (West was more aggressive) and from West's POV (she was).

While Alicia has never been a tragic figure per se, she di𓂃d lose her sight to the machinations of her super villain step-father the Puppet Master. That hint of✨ duality - the melancholy underneath her positive demeanor - is right in Wilson's wheelhouse.

Javier Bardem as Doctor Doom

The role of Victor Von Doom requires someone with terrifying gravitas and the acting ability to make the FF’s eternal foe more tragic than cartoony. Enter Javier Bardem, as imposing and chilling a villain actor as you can cast th🦄ese days.

Sure, he’d have to chew a little more scenery than he did as Anton Chigurre in No Country For Old Men, but that level of intensity is exactly what the role of Marvel’s most conflicted and arrogant vil𝔍lain calls for.

More than anything, what we’re looking for is a Doom that can hold his own against not just the FF, but the entire Marvel Universe. Bardem has the presence and talent to make him a ꦜuniverse-level threat, and the serious demeanor that would help avoid the pitfalls of previous big screen versions of Doom.

Javier Bardem also played the villain in Disney’s latest installment of&nb꧙sp;Pirates of the Caribbean, so he’s already part of the studio’s wider network.

Oscar Isaac as Namor

Unlike DC’s big screen Aquaman, Marvel’s Namor i𒅌sn’t a bombastic he🍌ro type. No, he’s more of a brooding monarch who has occasionally deigned to aide the surface world. More often, he’s been a kind of environmental anti-hero, raising hell against the folks who pollute his home in the ocean.

He’s also a well-known comic book hunk (we’re talking Winter Soldier level) – 💮and that’s the pearl in the oyster when it comes to the darkly handsome Oscar Isaac, an actor uniquely suited to portray both Namor’s brash anger and coy regality in equal measure.

Whoever winds up playing Namor will have to credibly cause Sue Storm’s eye to wander away from Reed Richards – and Oscar Isaac has the charisma and pure animal magnetism to play the savage king of the𓂃 sea. And of course, as part of the&nb𝐆sp;Star Wars franchise, he’s already in the Disney family.

Dev Patel as Silver Surfer

At age 29, Dev Patel would be a perfect contemporary to our pick for Johnny Storm (more on that l𒈔ater) – and he’d be the right choice to bring a bit of wide-eyed wonder to the usually solemn Silver Surfer/Norrin Radd.

Now, we don’t mean we’d want to turn him into a happy-go-lucky type. Rather, Patel has what it takes to play the ultimate alien explorer and bring something to the role that coulꦛd easily be lost under the layers of chrome CGI – Silver Surfer’s humanity.

Patel could portray the weight of the Surfer’s tragic backstory without losing the spark of imagination that comes with the Power Cosmic. We don't know where anyone ever got the idea the Surfer was like Gort from The Day 𒆙The Earth Stood Still under the silver. There’s a highly contemꦦplative, incredibly sensitive person in there.

Russell Crowe as Galactus

Okay, we're admittedly thinking of Galactus as a primarily CGI presence (not that we aren't demanding a comic book accurate representation - purple skirt and all), whi🧸ch informs our opinion on how the immense, cosmically hungry force of 🐓natures should be portrayed.

For this, we're looking to Russell Crowe - perhaps a slightly left-field choice, but that's what we like about it. Crowe's got the requisite bass in his voice to 🎉pull off playing Galactus, and he's self-aware enough to not go too far into the realm of po-faced stiffness in the face of a somewhat absurd role.

Glen Powell as Johnny Storm

We almost went with 26-year-old Blake Jenner﷽ as Johnny Storm but instead we couldn’t stop landing on his 30-yea🌜r old Everybody Wants Some co-star Glen Powell.

(We think) a star-in-the-making,ꦑ Powell is still more than a decade younger than our picks for his teammates/co-stars, highlighting൩ Johnny’s requisite youthful (if not teenage) dynamic in the group.

Powell has a kinetic, highly-verbal, life-of-the-party energy that suits Johnny well, as the member of the team t🎐hat most embraces his abilities and role as a public hero.

Plus♒ he’s pretty enough to credibly pass as youဣnger brother of our choice for Sue, which is no easy ask.

But more on that in a moment.

Ron Perlman as Ben Grimm

This might be the biggest no-brainer of all. Who better to play the ever-lovin’ blue-eyed🦹 Thing than the ever-lovin’ blue-eyed Ron Perlman?

Perlman’s got the exact kind of range that befits Ben Grimm &ཧndash; a wry, sarcastic wit wrapped in the pathos of his tragically inhuman form, and topped off with a heart of purꦐe, solid gold.

Perlman’s gravelly voice (pun 1𒁃00% intended) and experience playing all-too-huma𒁃n characters hidden under layers of make-up from the tragically romantic Beast to the iconically devilish Hellboy aren’t the only things Perlman’s got going for him. Like Aunt Petunia’s favorite nephew, Perlman’s a New York native of Jewish heritage – meaning he’s got firsthand experience with Ben’s POV.

Keanu Reeves as Reed Richards

54-year-old Keanu Reeves is in a bit of a renaissance at the moment thanks to the ever-popular John Wick franchise and his growing reputation as Hollywood’s kindest soul – and that’s part of why he’s perfect as theꦺ patriarch of the Richards family and the leader of the Fantastic Four.

Reeves has an impeccable resume for an MCU movie – comedies, romantic dramas, action, sci-fi, he’s pulled it all off with a cool demeanor that is spot-on for the FF’s resident know-it-all and one of t✨he smartest people in the world.

Yeah, we know he’s got the Bill & Ted “Whoa!” stigma, but Reeves is so much more than that. He’s the perfect choice to play the guy who keeps a straight face w🐻hile staring down the craziest, weirdest science stuff the MCU c🃏an throw at him.

Charlize Theron as Sue Richards

Charlize Theron as Sue R🍌ichards/Invisible Woman was the first choice we made for our fan-cast. Not only is Therꦿon the spitting image of Sue on the page, she’s got the gravitas and screen presence to give Reed a run for his money as the FF’s heart and soul.

While 20-something A-listers like Jennifer Lawrence, Margot Robbie, and Emma Stone made the short-list, we ꧅again view the FF as the “adults” of the ꦇMarvel Universe, seasoned science explorers led by Reed and Sue who are old enough to have kids and to be contemporaries of Iron Man and Doctor Strange.

And to that🌃 end, there’s no other choice but Charlize Theron, who could play a Sue more Reed’s equal, his window to t🍨he world who holds the FF together through sheer determination.

And as a bonus, Theron and Reeves have alre✤ady played a couღple together in two previous movies, and would have an instant rapport - like a married couple.
