At the 79th Cannes Film Festival, where cinematic storytelling has never been in short supply, one of this year’s biggest surprises came from AI.
On Thursday, ByteDance’s cloud platform Volcengine brought its Seedance 2.0 model to Cannes, where the company hosted an AI film showcase and premiered Hell Grind, a 95-minute AI-generated feature film billed as the world’s first full-length AI movie.
The production team behind the feature film comes from the US-based AI company Higgsfield, while its core video generation model is Seedance 2.0, developed by ByteDance.
This was not a 15-second AI clip or a proof-of-concept demo. Hell Grind arrived as a complete, theater-scale narrative feature — a sign of how rapidly generative AI is moving from experimental content creation into long-form cinematic storytelling.
What sets this apart is that long-form video generation has been one of AI filmmaking’s biggest technical bottlenecks. Most mainstream AI video tools today can only generate clips lasting between 15 and 30 seconds.
