AI Short Films Win. AI Movies Flop. Here’s Why

On October 23, 2026, China’s first fully AI-generated feature film, Sanxingdui: Future Past, opened on more than 10,000 screenings. By its fourth day, ticketing data showed an average of 0.3 viewers per screening.

This was not a weekend experiment. Bona Film Group, the studio behind some of China’s biggest war blockbusters, spent two years on it, with around 100 people and more than 1.2 million generated base images.

The paradox

At the same time, AI storytelling is thriving elsewhere. Tens of thousands of AI micro-dramas are uploaded to Chinese streaming platforms every month. AI short films fill festival programs: this year’s Grand Prix at Runway’s AI Film Festival went to an eight-minute drama by a filmmaker with no formal training.

Even Bona’s own 13-episode AI series, set in the same Sanxingdui universe, passed 200 million views on Douyin. Same team, same world, opposite outcomes. So what changes between eight minutes and a hundred?

What the video explores

• What the trailer reveals about the limits of today’s AI video, from faces and motion to script and sound
• Why two years is a very long time when the tools change every few months
• What the early days of CGI, from Tron to Final Fantasy: The Spirits Within, can teach us, and where that comparison stops
• Where AI filmmaking already works, and what the next test could tell us

Watch the video

The full breakdown is in the new Cosmo Edge Labs video. It runs about 12 minutes and needs no technical background: just curiosity about where AI video is heading.
