A featurette showcasing Jason Momoa's portrayal of Lobo in Warner Bros.' 2026 film Supergirl has been removed from YouTube, apparently in response to fan backlash over the potential use of AI-generated concept art for the character's design.
The video, which appeared online after the film's summer 2026 release, featured director Craig Gillespie discussing Momoa's performance while reviewing concept art on a laptop. Close examination by viewers suggested that some of the artwork displayed bore the hallmarks of AI generation, including a soft, blurred aesthetic and distinctive lighting.
Fans quickly voiced their criticisms in the video's comments section, with many pointing out the similarities to AI-generated content. Shortly after these reactions surfaced, the featurette was reportedly taken down from YouTube.
Neither DC nor Warner Bros. has issued an official statement regarding the video's removal or the allegations of AI art usage. This incident follows a difficult box office performance for Supergirl, which had grossed $124 million globally against a $170 million budget as of August 2026, making it one of the lower-grossing DC Comics adaptations. The film itself received a mixed reception, with IGN scoring it a 6 out of 10 and noting that its narrative struggled with borrowed elements from other movies.
Reports prior to the film's release indicated creative differences between director Craig Gillespie and DC Studios, with competing cuts being tested. Despite Supergirl's performance, Warner Bros. is proceeding with James Gunn's Superman sequel, Man of Tomorrow, with studio chief David Zaslav acknowledging that recent films have experienced underperformance.
In contrast, James Gunn's Superman was met with a more positive reception, earning an 8 out of 10 from IGN for its role as a "wonderfully entertaining, heartfelt cinematic reset" for the DCU.
