James Gunn Shares First Look At MAN OF TOMORROW Script - And He May Have Confirmed Brainiac!

James Gunn has taken to social media to reveal a first look at his script for Man of Tomorrow, and it seemingly confirms that Brainiac will serve as the Superman sequel's big bad. Check it out here...

DC Studios co-CEO James Gunn has just shared a first look at Man of Tomorrow's script, and he appears to be teasing—or even confirming—the long-awaited DCU debut of Brainiac. 

It's hard to say what other conclusion we should draw from the vintage medical illustration of a human head's anatomy. It might be a reference to Lex Luthor's intelligence or a way of comparing his human physiology to the alien Superman.

However, Brainiac would be a worthy choice of foe to bring Superman and Lex together as reluctant allies. 

The Superman sequel will see the latter don his green and purple War Suit from the comics, with Lois Lane, Hawkgirl, Supergirl, and Peacemaker among those expected to appear in the next chapter of Gunn's "Superman Saga." 

Fans have spent years waiting to see Brainiac on the big screen. The villain has appeared in TV shows like Smallville and Krypton, but we've yet to see a worthy interpretation of one of Superman's greatest foes in theaters. If he is in Man of Tomorrow, Brainiac should pose a physical threat to the Man of Steel, and an intellectual one to Lex. 

In the comics, Brainiac is an alien android from the planet Colu with a 12th-level intellect. Obsessed with collecting all knowledge in the universe, he shrinks and steals cities, including Krypton's Kandor, storing them in bottles.

His abilities include super-intelligence, technopathy, and shape-shifting. Frequently clashing with the Justice League, he seeks to assimilate all data, often at the cost of entire civilisations, and Brainiac's relentless pursuit of knowledge and lack of empathy have cemented his status as one of the DC Universe's most dangerous threats.

During a recent interview with Howard Stern, Gunn said, "It’s a story about Lex Luthor and Superman having to work together to a certain degree against a much, much bigger threat. It’s more complicated than that but that’s a big part of it."

"It’s as much a Lex movie as it is a Superman movie. I loved working with Nicholas Hoult. I relate to the character of Lex, sadly," the filmmaker continued. "I really wanted to create something extraordinary with the two of them. I just love the script so much.”

On social media, Gunn shared, "As I've said countless times, you can watch every project by itself, of course (just like you can watch Peacemaker by itself or watch Superman without seeing Creature Commandos). But Man of Tomorrow and [Peacemaker season 2] are very, very connected."

Do you think Gunn will actually let Superman WIN a fight in this one, or will it only be possible if he teams up with his good buddy Lex, who is a murderer?

@MotherGooseUPus - Seems like it'll be a while before we see any follow up. The manga was delayed until next year.

I wish they would adapt Moro and Granolah arcs but doubt they will at this point

Interesting image on there…

Either we are getting Brainiac or Ultra Humanite (the latter of which could be kinda cool since he was originally Superman’s arch nemesis until he was usurped by Lex who Supes has to reluctantly team up with in this)

Anyway , I could see us getting either but if we do get the former then you can bet Gunn will have him do the bottled city stuff since he’s a silver age fan!!.

Why aren't they calling it a direct sequel is the question

@0bstreperous - The same way BvS was (or wasn't) a direct sequel to MoS?
0bstreperous
0bstreperous - 9/22/2025, 12:51 PM
@UnderBelly - yeah but this is ridiculous if they aren't trying to repeat the Bvs mistake
UnderBelly
UnderBelly - 9/22/2025, 1:32 PM
@0bstreperous - I agree...

I also hoped Gunn would've passed the reigns onto someone else.

I liked Superman and all, but it actually feels kind of forgettable now that there's some distance since I seen it.

Not trying to be a Snyder fanboy, but MoS had more of a lasting appeal..maybe it was down to the controversial 3rd act, or the state of the landscape at the time, but I still look bad fondly on that movie. BvS...hell no.

@UnderBelly - I like BvS although I also like X-Men the last stand and Batman and Robin

Getting Brainiac on the big screen for the first time ever and it's a James Gunn's version. What a letdown.

YO!!! JAMES GUNN!!! IT'S YOUR BOY, BIG UPS ON THE DOWN LOW HOMIE g

Now for my first wish, since you called this film "Man of Tomarow", you better include this scene from the comic book "Whatever Happened To The Man of Tomorrow" and make it permanent, as you said "death will actually mean something in the Dcu"
User Comment Image


Speaking of death,for my second wish, you must include this scene, it's vitol for obvious reasons, not to mention you've been building to this character's death since the series started years ago.
User Comment Image


For my third wish, you must do a shot for shot remake of this classic Jimmy Olsen scene, Show Snyder how it's done, actually show the gruesome details and include a one liner from Jimmy before and after the bullet enters his computer.
User Comment Image

Also, I get a forth wish for good behavior.
Immediately toss that garbarge script into the bin and hire an actual film writer like Zack Snyder to do the job that you clearly can't.

Phenomenal. Loved the first Gunn Superman, great to see someone finally getting Lex and Superman right in the movies. Best Superman in live action of the last 30 years, easily. Best live action Luthor ever.

Demon Slayer is creeping up on Superman on the worldwide box office charts. If it surpasses it, then Superman is UNLIKELY to end up in the top ten box office films of 2025 with Zootopia, Wicked, and Avatar coming up to bat. What a sad state of affairs for Superman. This would be yet another blow to the shill narrative that this movie was a success. Man of Steel ended in the top ten at the end of its 2013 run.

It is just laughable....

I wonder who's gonna play Superman and Lex Luthor.

I don't think it should be Corenswet and Hoult. I love their versions of Superman and Lex and I love that movie and that universe but this should be another universe with new versions of the characters for no reason at all.

@ObserverIO - It's definitely going to be Corenswet and Hoult. lol

Brainiac is a no-brainer; he's easily one of Superman's best Rogues.
