At first glance, it could be the trailer for a new Hollywood blockbuster starring Brad Pitt and Tom Cruise.

“This was a 2 line prompt in seedance 2,” Irish filmmaker Ruairí Robinson clarifies in a caption on X of the 15-second clip, which shows two of the movie industry’s biggest stars locked in a fistfight on a crumbling rooftop, complete with sweeping camera angles and crisp sound effects.

The viral AI-generated clip has garnered more than 1.8 million views since it was posted on X last week, triggering panic and backlash from Hollywood.

Deadpool screenwriter Rhett Reese reposted the video with the message: “I hate to say it. It’s likely over for us.”

Much has been made of the threat that artificial intelligence poses to a range of industries, including Hollywood. From screenwriters to special effects teams, the dawning realization that the latest tools can now produce highly realistic likenesses alongside high-octane production has only deepened the anxiety among already beleaguered industry insiders.

Reese expanded on his stance in a follow-up X post: “My glass-half-empty view is that Hollywood is about to be revolutionized/decimated. If you truly think the Pitt v. Cruise video is unimpressive slop, you’ve got nothing to worry about. But I’m shook.”

The clip was created using Seedance 2.0—a new AI service from ByteDance, the Chinese company that also owns TikTok—which launched last Friday. Upon its release, X was quickly flooded with clips from others trying their hand at generating their own major motion pictures. An alternate ending to Game of Thrones went viral (it has since been taken down), as did riffs on Spider-Man, Shrek, and more.
