Earlier this year, OpenAI and other Hollywood studios presented the futuristic promise of AI tools that they said could help make the business of creating movies and television shows faster, easier and cheaper.

The tech companies wanted access to troves of footage and intellectual property from series and films that they could use to train and support their models. It is the kind of thing AI technology needs to create things like videos and script notes.

So far, though, despite all the hype and anticipation, not much has come of those talks.

The most prominent partnership was announced in September between New York-based AI start-up Runway and Lionsgate to help with behind-the-scenes processes such as storyboarding.

But none of the major studios have announced partnerships, and they are not expected to until 2025, said people familiar with the talks who were not authorised to comment.

There are many reasons for the delay. AI is a complicated landscape where regulations and legal questions are still evolving. There is also doubt whether audiences would accept films made primarily with AI tools.
