Simu Liu Blasts Viral AI Clip of Brad Pitt and Tom Cruise Fighting

Simu Liu has never been one to shy away from a fight, especially when it comes to defending the integrity of his craft against the encroachment of artificial intelligence. The Marvel star recently took to social media to dismantle a viral video that many claimed represented the terrifyingly realistic future of filmmaking.

For Liu, the footage was less of a digital revolution and more of a masterclass in what a total lack of physical expertise looks like when rendered by a computer.

The controversy began when filmmaker Ruairi Robinson shared a hyper-realistic, AI-generated clip of Brad Pitt and Tom Cruise engaged in a brutal rooftop brawl. While some industry veterans, including Deadpool writer Rhett Reese, reacted with alarm and suggested that the era of human-led cinema might be nearing its end, Liu remained unimpressed.

He focused specifically on the mechanics of the combat, which he found to be fundamentally flawed from a martial arts perspective.

Taking to his platform to offer a reality check, Liu dismantled the praise surrounding the clip’s technical execution. He wrote, LOL anyone who has ever watched a martial arts movie knows this is absolutely dog***. For an actor who spent months undergoing rigorous training for his breakout role as Shang-Chi, the weightless and illogical movements of the digital avatars were impossible to ignore.

This is not the first time Liu has stood as a vocal critic of the industry’s pivot toward generative technology. He has consistently championed the human element of production, arguing that art loses its essential soul when it is stripped of the physical contributions of background actors and stunt performers.

He recently noted that art is art because it’s human, and that the subtle rhythms of a living person cannot yet be replicated by a prompt.

The actor’s frustration with the “AI threat” is balanced by an incredibly productive period in his own career. He recently starred in the sci-fi espionage thriller The Copenhagen Test, which premiered on Peacock to strong reviews.

In the series, he plays Alexander Hale, a government intelligence analyst whose mind has been hacked, a role that he says allowed him to explore the complexities of his own identity as a first-generation immigrant.

Fans of the Marvel Cinematic Universe are also gearing up for his return to the big screen in the highly anticipated Avengers: Doomsday. Slated for a 2026 release, the film will see Liu reprise his role as Shang-Chi alongside a massive ensemble cast.

Whether he is calling out tone-deaf industry takes or preparing for a Broadway stage, Liu continues to lead with a mix of humor and fierce conviction. His critique of the Pitt-Cruise AI fight highlights a growing divide between those who see technology as a shortcut and those who view the physical demands of acting as irreplaceable. As the debate over AI in Hollywood intensifies, Liu’s voice remains a grounded reminder of the value of hard-earned expertise.
