OpenAI backs first AI-generated animated feature film

OpenAI has officially backed “Critterz,” an animated feature film that will be created primarily using artificial intelligence technology, marking the company’s most significant venture into Hollywood entertainment. The project, initially conceived as a groundbreaking short film in 2023, is now being developed into a full-length feature by UK-based Vertigo Films and AI creative studio Native Foreign, with production set to begin and a planned debut at the Cannes Film Festival in May 2026.stocktwits

The film represents a milestone collaboration between traditional filmmaking and AI technology. Chad Nelson, a creative specialist at OpenAI who wrote and directed the original short, is serving as consulting producer alongside the “Paddington in Peru” writing team of James Lamont and Jon Foster, who have been brought on to pen the feature-length screenplay. The project has secured a budget of under $30 million, significantly lower than typical animated productions which often cost hundreds of millions of dollars.econotimes

Breaking New Ground in AI-Enhanced Filmmaking

The original “Critterz” short film made history in 2023 as the first animated project to combine visuals generated by OpenAI’s DALL-E system with traditional animation techniques. The comedic science documentary follows forest creatures who interrupt their own nature documentary narrator, creating an unexpected meta-narrative that charmed audiences at prestigious festivals including Annecy, Tribeca, and Cannes Lions.variety

Native Foreign, the AI creative studio behind the project, demonstrated the rapid advancement of AI technology by releasing “Critterz: Remastered” in February 2025 using OpenAI’s Sora video generation model. This remastered version showcased a dramatic improvement in visual quality and character animation compared to the original, providing a compelling proof-of-concept for the feature-length adaptation.nativeforeign

Production Strategy and Industry Impact

The feature film will blend human creativity with AI assistance, employing professional voice actors for character performances while using AI-generated visuals enhanced by human artists’ hand-drawn sketches. According to The Wall Street Journal, producers aim to complete the film in approximately nine months, a remarkably compressed timeline compared to traditional animation workflows.econotimes

James Richardson from Vertigo Films emphasized the project’s significance, stating that “the original ‘Critterz’ showed us how AI tools can help filmmakers tell beautiful and entertaining stories”. The production model represents what industry observers see as a potential blueprint for future AI-assisted filmmaking, combining cost efficiency with creative storytelling.vertigofilms

This venture comes as Hollywood grapples with AI’s role in entertainment production. Major studios are increasingly experimenting with AI tools for pre-visualization and concept development, while creative unions have negotiated protections for their members. The success or failure of “Critterz” at Cannes could significantly influence industry attitudes toward AI-generated content and its commercial viability in theatrical releases.yahoo
