It’s official: AI was used to make Supergirl.
A newly released behind the scenes featurette reveals that AI was used to conceptualize the design of Jason Momoa’s Lobo.
The clip shows director Craig Gillespie sitting at a laptop with Momoa, clicking through screen after screen of AI-generated Lobo concept images.
Warner Bros. Discovery, the studio’s parent company, has since pulled the video from YouTube as the backlash spread.
WB Pulls The Video As The Backlash Spreads
The featurette runs over six minutes and chronicles Momoa’s transformation into the Main Man.
It went up on the Warner Bros. Entertainment YouTube channel to promote the film’s digital release, with the 4K disc arriving September 8.
Entertainment news account DiscussingFilm posted the AI segment Thursday morning, and it blew past 2.5 million views within hours. It appears as if they yanked the video, too.
By early afternoon, the video was gone, with reports stating WBD yanked it off YouTube as the criticism mounted.
Fans immediately pointed out the obvious. Lobo was created by Roger Slifer and Keith Giffen in 1983, giving the studio more than four decades of comic book artwork to pull from.
One viral reply blasted the studio for turning to AI on a character with thousands of existing illustrations, calling the movie a joke.
DC Redditors are also in full blown panic mode. “I’m praying this is fake,” posted a Redditor.
Exactly What Our Insiders Said In March
None of this is a surprise to CBN readers.
Back on March 2, nearly four months before Supergirl hit theaters, I posted on X what my insiders had been telling me about James Gunn’s DCU, in response to a video from YouTuber John Campea.
One line stands out today: “Gunn doesn’t use practical. He shoots blue/green screen on digital and fixes things in post. He’s used AI.”
Here is the post in full:
Campea’s new video is hilarious:
Gunn’s already been under financial restraints under Zaslav.
His DCU cannot compete with Marvel. Man of Tomorrow will not be able to compete with Avengers: Secret Wars. Supergirl is already expected to be a big bust.
Gunn doesn’t use practical. He shoots blue/green screen on digital and fixes things in post. He’s used AI.
His Superman isn’t a success. It made less money than previous films. It tanked massively internationally. Ted Sarandos confirmed it underperformed. Sony pic head confirmed foreign box office is important.
Gunn’s HBO shows failed. Peacemaker lost half its audience and got canceled.
Most of Gunn’s Gods and Monsters and DCU plans got canceled.
He’s been forced to only doing Superman family saga projects.
Gunn’s “graceful exit” is already being planned with the shill media already on board.

That was March.
Supergirl went on to open at $37 million in June and exited theaters this month as the lowest-grossing DC movie of all time at $125.9 million worldwide.
The flop was so big it got called out in WBD’s Q2 earnings, with studio profits crashing 89 percent.
Insiders: Gunn Is Using AI On Man of Tomorrow
Here’s the part Warner Bros. can’t delete off YouTube.
Per our insiders, the AI use didn’t stop with Supergirl. We’re told Gunn has been using AI on Man of Tomorrow, the Superman sequel.
We’re further told his writers room uses it, and that’s how Man of Tomorrow got off the ground so quickly.
Consider the timeline. The film went from announcement to cameras in a matter of months, has been shooting since April, and Gunn just confirmed day 79 of filming.
As I exclusively reported last month, sources describe the script as “Frankensteined” together from previous ideas, with a turnaround so fast there was no time to put a proper production and art department together.
Those same sources noted Gunn is fortunate to have AI now, so he won’t face the last-minute VFX fires Marvel became notorious for.
It also explains how the production keeps stacking cameos by the week: a loose Marvel-style outline lets Gunn keep bolting on characters as a reaction to the Supergirl backlash.
The Timing Could Not Be Worse
The AI reveal caps a brutal week for Gunn and his DC Studios co-boss Peter Safran.
Waller and Paradise Lost are dead, and Lanterns premieres Sunday as a show that was HBO’s cost-cutting note all along.
Then there’s this: the Writers Guild of America, the union representing Hollywood writers, is among the parties suing to block the $110 billion Paramount merger, with the trial set for March 2027.
Insiders say the man running DC Studios put AI in the writers room anyway.
Per the March post, the graceful exit is already being planned. Per my insiders since, expect Gunn and Safran to step down as heads of DC Studios to focus on Man of Tomorrow once Paramount takes over, and then they are out.
Add this to the record: Warner Bros. put the Supergirl AI use on its own YouTube channel, then deleted it.
The Man of Tomorrow AI use, per our insiders, you’re hearing here first.
