How this move by ChatGPT maker OpenAI may have ended animated movie Critterz's Cannes 2026 debut plans

ChatGPT-maker OpenAI has reportedly killed animated movie Critterz's Cannes debut dreams for this year. According to a Bloomberg report, the AI-assisted animated feature missed its planned in-festival premiere at the Cannes Film Festival after OpenAI shut down Sora, the generative video model that was a key part of the project’s production pipeline. While Critterz was presented to international buyers through private screenings at the Cannes market, the film did not secure the festival debut producers had aimed for. According to the report, the project was created using OpenAI's creativity engines, namely DALL-E and Sora, with Sora being used to generate video sequences of the movie.Sora was reportedly discontinued by OpenAI in March due to low user engagement and rising costs. The consumer-facing aspect of Sora had been shuttered in April, while access to the API would presumably be cut off before the end of this year. According to Bloomberg, Critterz was reportedly left without a key element of its workflow pipeline mid-production. The film is based on a 2023 short produced by Chad Nelson, using OpenAI tools. The feature adaptation is being produced by AGC International, Vertigo Films and AI studio Native Foreign.Critterz had been promoted as a test case for whether generative AI could reduce animation production timelines. Producers reportedly targeted a release cycle of around nine months, compared with several years often associated with traditional animated films.The project was described as “human-led but AI-assisted,” with a reported budget of less than $30 million. Its planned Cannes debut was expected to help demonstrate whether AI-supported filmmaking could scale commercially.However, Sora's disappearance has created uncertainty about the technical foundation of the project. Producers have not publicly explained which tools, if any, replaced Sora after its shutdown.The report claims that OpenAI has been redirecting efforts toward AI systems designed for world simulation and robotics research rather than consumer video generation products. The shift could leave projects developed around earlier OpenAI video models facing adaptation challenges as production continues.However, Critterz still remains in development and may target a future festival window, potentially in 2027. By then, the competition to claim the title of the first mainstream AI-assisted feature film may look very different, as more studios experiment with generative AI tools.
