Warner Bros. removed a Supergirl behind-the-scenes video after viewers spotted what looked like generative AI concept art tied to Jason Momoa's Lobo. The film, directed by Craig Gillespie, has already weathered a rocky box office run, and this fresh episode adds another layer of strain. What started as a routine promotional clip meant to spotlight Momoa's take on the intergalactic bounty hunter spiraled fast once eyes caught something off. The digital age offers little room for quiet missteps, and Warner Bros. is learning that lesson firsthand.

As the internet dissected every frame of that now-vanished video, one question lingered louder than the rest: what exactly was Warner Bros. trying to hide?

Warner Bros. removed a Supergirl behind-the-scenes featurette from its official YouTube channel after viewers accused the studio of using AI-generated concept art for Jason Momoa's Lobo. The video, uploaded to promote the film's digital release, showed Craig Gillespie's team reviewing multiple Lobo designs with Momoa on a laptop screen. Clips of that segment spread rapidly across social platforms on August 13, prompting a swift takedown. The removal only deepened public suspicion.

The same featurette remains visible inside the extras section of the digital release, at least for now, leaving audiences puzzled about the inconsistency. Neither Warner Bros. nor Gillespie has issued any statement addressing the claims. The optics grow sharper considering Supergirl carried a reported budget near 180 million dollars, a number many felt should have covered human concept artists. This tension sits awkwardly beside DC Studios co-CEO James Gunn's long-standing rejection of artificial intelligence in creative work.

While the AI backlash rattled Supergirl's promotional rollout, another creative choice inside the film itself was already dividing longtime readers.

Milly Alcock's Supergirl also reshaped the fate of the villain Krem of the Yellow Hills, replacing the comic's more restrained conclusion with a decisive k***. In the original comic, Krem instead spends roughly 300 years imprisoned in the Phantom Zone before seeking forgiveness from an older Ruthye. The film instead has Kara stop Ruthye from killing Krem, only to end his life herself moments later. Longtime readers felt the swap erased the story's message about breaking cycles of vengeance.

Screenwriter Ana Nogueira has said the finality was part of her original pitch, arguing the comic's distant future resolution would not translate well on screen. Director Craig Gillespie and co-CEO Gunn reportedly backed the choice fully, never even filming an alternate version. Some viewers argued the change made Kara appear inconsistent, since she stops a child from dying only moments before doing it herself. Between the altered ending and the AI fallout, Supergirl continues facing scrutiny it did not anticipate.
