MAN OF TOMORROW: James Gunn Reveals Comic Book Inspiration For Brainiac And Why He Didn't Cast An A-Lister

Man of Tomorrow director James Gunn has hinted at the comic books that are influencing his take on Brainiac, and explains why he cast Lars Eidinger as the villain.

Yesterday, the news broke that James Gunn has cast Lars Eidinger (All the Light We Cannot See) as Man of Tomorrow's Brainiac. The response has been positive, even though many DC fans are unfamiliar with the German actor's work. 

Gunn has an eye for casting, so chances are Eidinger will blow us all away as the Superman sequel's big bad a couple of summers from now. Still, some fans have understandably questioned why Gunn didn't cast a more recognisable name.

Responding to praise for his decision to choose the right actor for the part (rather than an A-list name), Gunn said on Threads, "I wouldn't leave Chris Pratt, David Corenswet, Dave Bautista, Karen Gillan, Milly Alcock, or Daniela Melchior, etc, out of that mix! All of them were people who came in and auditioned and weren't thought of as 'movie stars.'"

"I'm always interested in casting the best person for the role," Gunn continued, "no matter what route that takes - and often the best route is through auditions." Emphasising that point, when he was quizzed on which past movie or TV show convinced him Eidinger was the right choice for Brainiac, the DC Studios co-CEO replied, "His audition."

The actor must have really blown Gunn away with his take on Brainiac, similar to how the likes of David Corenswet and Milly Alcock won the roles of Superman and Superman. For whatever reason, good or bad, casting household names clearly isn't a priority for the DCU.

The Man of Tomorrow helmer has already debunked reports about Dave Bautista being in the running for Brainiac, but what about Matt Smith, Claes Bang, and Sam Rockwell? "None of them even screen tested," Gunn declared. "I'm not even sure any of them auditioned. Total made-up stuff."

Now that we know who is playing Brainiac, all eyes are on what interpretation of the villain we get in the DCU. Like most DC characters, we've seen multiple versions of the character on the page since his 1958 introduction, and he's previously appeared in live-action projects such as Krypton and Smallville.

"I love aspects of many versions of the characters," Gunn teased, "from the 1950's Binder stuff to the surprisingly scary Wolfman stuff to the animated versions and up through the truly creepy and wonderful, current Absolute Brainiac."

Reading between the lines, it sounds like Gunn might be leaning towards the scarier versions of this character, not the more formidable, physically imposing take introduced by Geoff Johns and Gary Frank (which served as Krypton's main inspiration). The filmmaker is a big horror fan, so that version appealing to him makes sense.

Written and directed by James Gunn, Man of Tomorrow stars David Corenswet as Clark Kent/Superman, Nicholas Hoult as Lex Luthor, Rachel Brosnahan as Lois Lane, Isabela Merced as Kendra Saunders/Hawkgirl, and Frank Grillo as Rick Flag, Sr.

Several actors and characters are rumoured to appear, including Aaron Pierre's John Stewart/Green Lantern and John Cena's Peacemaker.

Recent reports have suggested Gunn is looking to cast the DCU's Wonder Woman, and while the filmmaker has remained silent on that, he did recently confirm that Steve Trevor won't appear in the Superman sequel.

Man of Tomorrow arrives in theaters on July 9, 2027.

Apart from his friends, no major celebrity wants to play in this stupid universe he is creating.

Remember when Gunn said ''I talked to Affleck and he want's to direct a movie" only for Affleck to state a few days after "absolutely not, I saw what they are doing and I'm not interested".

Gunn is finished, his days are numbered.

@KyoShiRo330 - Has Gunn ever given an impression that he specifically "targets"/desires big celebrities in his projects? Back in his GotG days, when working with Disney money and having the popularity of the overall MCU backing him up, the biggest names he cast were probably Stallone and Russell, both past their primes (saying this as someone who loves both as actors) and the former was basically just a cameo. In The Suicide Squad the one big celebrity actor was Margot Robbie, who he "inherited" from the other movies and was probably forced upon him (considering how disconnected Harley is of the main story, I would be extremely suprised, if Gunn actually wanted to use her), while the rest were character actors. Maybe you could argue for John Cena, but I don't think he is some A-lister. Gunn clearly cares more about finding someone who fits his vision than how famous they are.

And when did getting big name celebrities became some end-all-be-all? Most of the grestest comic book castings were not big celebrities, before being cast for said roles. Now that we know that Brainiac isn't a previous alumni of his nor a close friend, you guys just started to grasp at the next set of straws.

He's trying to recreate Marvel style with DC characters & it DOES not work. But his disciples & shills can't critique nothing Gunn has done. Creature Commandos was supposed to be this major thing has flopped & headed to Youtube for FREE! Peacemaker Flop! Superman Flop though they move the goalpost & says $615 Million is a Successful blockbuster 😂🤣😂😂😂

@mck13 - Matey, cultist” or not, you’re just tossing buzzwords instead of looking at the actual [frick]ing numbers.

Creature Commandos going to YouTube doesn’t mean flop, it [frick]ing means WBD is pushing reach, the same tactic HBO used with Game of Thrones [frick]ing pilots.

Peacemaker wasn’t a flop either; it was one of Max’s highest engagement shows during Season 1. You may not like Season 2, but that doesn’t rewrite the [frick]ing metrics.

And Superman at $615M for a reboot with a completely new cast, new universe, and no Batman, Joker, Aquaman or Wonder Woman [frick]ing support?
In today’s [frick]ing post-pandemic climate?
That’s not a flop, that’s a [frick]ing foundation.

Studios care about trajectory, not nostalgia for 2019 [frick]ing ticket sales.

Gunn isn’t trying to recreate Marvel; Marvel tried to recreate Gunn.
Guardians defined the tone that half the MCU then copied for a decade.

The DCU is doing something different:
Character-first, long-term, slow build, no [frick]ing reliance on celebrity bandaids.

You don’t have to love the choices, but pretending every shift in strategy is “failure” isn’t analysis, it’s [frick]ing coping.

And the crazy part?
We’re only one movie in. The actual DCU hasn’t even [frick]ing started yet.

THEKENDOMAN - 12/21/2025, 5:59 AM
Exactly, this is the smart strategy people keep pretending not to [frick]ing understand.

With characters as iconic as Brainiac or Superman, the character is the star.
The actor benefits from the role, not the other way around. You don’t need a $ 20 million price tag A-lister when the name Brainiac already carries 60+ years of [frick]ing brand power worldwide.

That’s why Chris Pratt wasn’t a household name before Guardians.
Why David Corenswet wasn’t a blockbuster lead before Superman.
Why Milly Alcock, Daniela Melchior, and even Bautista himself blew up AFTER the roles, not before.

Casting lesser-known but elite talent lets you [frick]ing:

1. Save money on salaries and put it INTO the story, the VFX, the [frick]ing world-building.

2. Build new stars instead of recycling the same [frick]ing Hollywood faces, ie. Marvel.

3. Let the character shine without the actor’s [frick]ing celebrity overshadowing it.

4. Keep fans focused on the performance, not the [frick]ing PR machine.

And for the unpopular or obscure characters, like Mister Terrific or Hawkgirl, pairing them with big legacy icons (Superman, Lex, Brainiac) automatically boosts their [frick]ing visibility.

They feed off the universe’s popularity, exactly how it should [frick]ing be.

Gunn is building a sustainable, character-first DCU, not a [frick]ing “who’s the biggest celeb we can buy this week” circus.

It’s [frick]ing long-term thinking. It’s [frick]ing world-building.

And honestly? It’s [frick]ing working.

Lars is a perfect example. Phenomenal [frick]ing actor, [frick]ing terrifying range, [frick]ing zero ego, and now he gets to become the [frick]ing definitive Brainiac.

People will know his name because of the [frick]ing role.

That’s how you build a [frick]ing universe properly. [frick]ing Yes, James!!

The Marvel blueprint is lived and now dead and now dead and [frick]ing gone.

@THEKENDOMAN - That's great. But it is still "The Marvel Blueprint" since most of the Marvel characters are played by relatively unknowns or B-listers who played the character and became A-listers.

Or do you really think Hemsworth, Holland, Hiddleston, Olsen, Pratt, Renner or even Evans were household names before Marvel? And RDJ was an A-lister in the 90's but no one wanted to hire him before Iron Man. So, even he came back to the A-list because of Marvel.

So, while your heart's in the right place, the way you are using it to differentiate and as a bullet against Marvel is just not gonna work.
THEKENDOMAN
THEKENDOMAN - 12/21/2025, 9:28 PM
@SpiderParker - Matey, you’re absolutely [frick]ing right about one thing: Marvel built its [frick]ing universe on emerging talent. Hemsworth, Pratt, Evans, Hiddleston, even RDJ on his comeback, all [frick]ing true.

My point isn’t that Gunn invented that [frick]ing strategy.

It’s that Marvel stopped [frick]ing doing it, and Gunn is actually returning to what worked in the first place.

That’s the [frick]ing distinction.

Marvel started with:

Hungry [frick]ing actors

Character-first [frick]ing storytelling

Modest [frick]ing salaries

World-building that didn’t rely on [frick]ing celebrity power

And it [frick]ing worked.

Then Marvel shifted into:

[frick]ing constant stunt casting

[frick]ing hiring A-listers for cameo hype

[frick]ing leaning on celebrity familiarity instead of character iconography

[frick]ing ballooning budgets driven by actors, not story

Gunn isn’t “copying Marvel, mate .”

He’s following the [frick]ing original formula they’ve drifted away from, and applying it to DC characters where the brand power is [frick]ing already enormous.

Superman. Lex. Brainiac. These characters sell themselves.
You don’t need a $15M face to validate them; the character does the [frick]ing heavy lifting.

And Gunn’s approach adds something Marvel rarely did:

Elevating obscure characters by pairing them with legacy icons [frick]ing immediately.

Mr Terrific next to [frick]ing Superman?

Hawkgirl next to [frick]ing Lex and Brainiac?

That’s a shortcut Marvel never [frick]ing had.

So yeah, you’re right that the origins are [frick]ing similar, but where Marvel lost the [frick]ing thread, Gunn is staying committed to the [frick]ing core philosophy:

Cast talent, not [frick]ing headlines

Build stars, don’t [frick]ing buy them

Let the character be the [frick]ing celebrity

And honestly? It’s already [frick]ing working.

For [frick]’s sake.

SpiderParker - 12/21/2025, 10:52 PM
@THEKENDOMAN - I'm not sure why you think they are going for stunt casting or saying casting celebrity for cameo is a bad thing. For a multiverse movie, were they supposed to get some random guy? They did that with John Krasinski and I'm actually pissed about that since he could have actually been a good Reed. Every other guy though? Ex-Marvel actor.

Yes, they tend to get the A-listers for antagonist roles. What's wrong with that? The only A lister main lead I can think of in recent times is Pedro Pascal. Care to name a few others?

Are you pissed on that one guy for that one movie and dishing it out on the entire MCU? Or are you pissed they have different other universes to pull characters from like the Sony and Fox universes and dishing it out on MCU?

I agree, Gunn's choices to save bucks before the movie is released will help the movie make a bigger profit even if it doesn't do great numbers like it did with Superman but that doesn't mean, Marvel should just recast people since they have become A-listers after joining the MCU. DCU is in its infancy and building good will take a whole lot of time especially since the disastrous SnyderVerse so these tactics are good. But once it hits a decent zone, even they will fall under the same umbrella. Secret Wars will mark MCU's 20years so its really unfair of you to say they are only going for A-listers when most of them have only become A-listers after doing this for a while.

These are two types of collaborations we are talking about, one where a underdog goes against someone seasoned so people can root for the underdog when goes toe to toe and eventually wins, another where people of equal caliber are shown together so that no one upstages each other but still manage to create lasting impact. Neither are bad, it all works depending on the project and instance. Even someone like Holland who was quite new at that point, delivered something very nice in Infinity War even though he was surrounding by great talents.

That was a movie where so many A-listers were there, each of them giving their best and having scene-stealing presence yet the underdog also got the chance to shine through. And that movie itself is a great example why both can work depending on the project and instance even in the same movie.

But, its still smart for Gunn to save bucks early on since movies in theaters are pretty much dead right now so playing for the long game is the best move.
THEKENDOMAN
THEKENDOMAN - 12/22/2025, 9:22 AM
@SpiderParker - Very nicely broken down and all fair points, matey. But I think you’re slightly missing the distinction I’m drawing.

I’m not saying Marvel “should stop using A-listers.”
I’m saying the MCU shifted from:

Phase 1–3: “Actors become stars because of the characters”
to
Phase 4–5: “Characters exist to service celebrity appearances.”

That’s the difference.

Cameos aren’t the problem.
Dependency on cameos is.

In the early MCU:

Evans became Cap

Hemsworth became Thor

Hiddleston became Loki

Pratt became Star-Lord

Marvel made stars.

But by Phase 4–5?
It’s become:
“Who can we plug in for hype?”
“Who can trend on Twitter?”
“Who can cameo for nostalgia points?”

That’s where the shift happened.

Doctor Strange 2 became a cameo machine.
The Marvels was written around old MCU connective tissue to keep the structure standing.
Quantumania relied on the idea of Kang more than the character.
And yes, Secret Wars is looking like a celebrity multiverse parade.

Not bad… just a completely different strategy than what built the MCU.

Gunn’s approach is the opposite, and that’s why I emphasise it:

Build stars in the roles, don’t rent them.

Let iconic characters be the brand, not the actor’s Instagram following.

Spend the money on the film, not the payroll.

Use legacy characters to elevate new ones, not to hide weak writing.

And yes, you’re [frick]ing absolutely right:
DC is in the rebuilding era, so the “character-first” approach is precisely what’s needed now.

Superman doesn’t need an A-lister.
Brainiac doesn’t need an A-lister.
Lex doesn’t need an A-lister.

The roles are the draw.

Marvel had that once.
DC is doing it now.
Different phases, different [frick]ing needs.

No hate toward Marvel, just calling out how the strategy changed.

And honestly?
For where DC is right now, Gunn’s long-game approach is the most imaginative play on the [frick]ing board.
SpiderParker
SpiderParker - 12/23/2025, 12:22 AM
@THEKENDOMAN - They are on their multiverse phase so cameo are a given even if they don't serve the purpose to the character themselves, they serve a purpose in showing us that the alternate universe has people filled with characters we know about. Which after those specific cameos, now gives us a legitimate build up to Secret Wars without people thinking "how did that fox character come into this movie."

And, if they had done a lot with those fox characters then their presence in Secret Wars would be in the lines of "Eh, we already got that before in DS2." They had to use them to expose us to the multiverse without using them too much that upcoming movies will suffer for it. These kind of build ups are what Marvel were known for during phase 1 to 3 as well. Only difference is, too many projects and too much streaming content made people lose their interest, excitement and hype anyway.

They are still true to that but times have changed and people don't have that much patience for the C-list as they had for the previous B-list heroes. It just didn't resonate. They did push for new heroes and actors but people just want the old ones back. At least for Marvel. It's true for DC as well but instead of pushing for full projects, Gunn is sprinkling them elsewhere. Something Marvel has done previously as well but right now the legacy heroes are mostly dead or MIA so fans are not interested.

In anyway, for Marvel, this will pay off soon enough.

There's two things though. Nicholas Hoult is an A-lister and sometimes its good to have a few to give the hero a sense of threat but I'm not against the Brainiac casting in anyway. Secondly, your words reminds me of this.

"Part of the Marvel-ization of Hollywood is... you have all these actors who have become famous playing these characters. But they're not movie stars. Right? Captain America is the star. Or Thor is the star. I mean, I'm not the first person to say that. ...it's these franchise characters that become a star."

And that's just not true. Those characters are only stars because of the people who played them. Even if Joker is beloved, Jared Leto proved the character portrayed in a way that doesn't resonate with audience will not become the star and rip off a Star's power as well. You will counter that, Leto should be the reason, they should have gone with an unknown but that's not the reason why it failed. The characterization was the problem not the actor's ability. I don't blame any of the actors for the mess of DCEU, they were all good actors, except Gal perhaps. And going with unknown actors would have only put the DCEU in the graveyard sooner. In fact, the only reason that universe ran that long was cause of the stars attached to it which should be evident after what terrible things were done to the characters of Superman and Batman.

The SnyderCult would be dead before it was born if those stars didn't do the heavy lifting for that mess of a universe.

The best thing that can happen is when good actors get to portray parts that are depicted and characterized nicely. It could be an unknown or already established A-lister, it doesn't really matter.

@FinnishDude - Lmao Gunn's fanboys are delusional. Stallone alone is an A lister and nobody's want to play in his goofy ass universe. That's it.

And yes, having A lister is important for any blockbuster. If you don't understand why it's on you. Is it fair? Should it be important? No, but it is what it is tho.

And you are right for TSS, but how did this turn out box office wise? Lmao.

@THEKENDOMAN Dude, Gunn is literally making Marvel movies but at DC. Even the ones he didn't direct look like cheap GoTG knock-offs.

As for big A list stars. The first guardians movie lacked any real A listers and it blew up like at the box office and pretty universally loved

@KyoShiRo330 - Thanks for the link matey.

I get your point about A-listers, but with characters like Superman, Lex, and Brainiac, the character is already the brand. The actor benefits from the role, not the other way around.

That’s why Pratt, Gadot, Momoa, Bautista, etc. all became stars after their comic roles, not before.

Gunn’s strategy is simple:
strong actors + iconic characters = new stars and a sustainable universe.

Lars fits that perfectly. He becomes Brainiac, rather than “a celebrity playing Brainiac.” And the DCU still brings in big names where it actually matters.

It’s not copying Marvel, it’s building something long-term, character-first. And honestly? It's [frick]ing working.

TheVisionary25 - 12/21/2025, 6:08 AM
Honestly , I’m not sure why not casting A-listers is such a big issue considering even the MCU when it started didn’t even do that (for the most part)…

Plus while they certainly might have their fanbases , most movie stars nowadays don’t have the same pull like in the past so I feel it wouldn’t affect ticket sales much nowadays nor the budget of the films since the mostly unknown/lesser known actors wouldn’t cost very much at least initially until their respective films may be successful thus then they can increase their price.

From what I have seen of Lars via clips , he seems like a solid actor that will do well as Brainiac so that’s all that matters imo!!.

PS: In regards to this version of Brainiac , I can see Gunn taking inspiration from all the iterations he mentioned above and cherry pick which elements of each he likes the most to create his own take on the character which I could see being a bit creepy yet fiercely intelligent aswell given Lars’s vibe & James sensibilities imo.
