The copyright battle between Hollywood’s major studios and AI image company Midjourney has changed direction. Midjourney, the defendant, is now demanding that Disney, Universal and Warner Bros. reveal in court how they use artificial intelligence inside their own operations. The studios that accused Midjourney of infringement now find themselves defending their own AI practices.

There is a structural reason this fight keeps escalating. Generative AI has already seeped into nearly every stage of content production and distribution, from storyboarding and visual effects to marketing, and the studios themselves have been building or adopting AI tools internally. Many of those tools are suspected of resting on the same foundation as Midjourney’s: models trained on large volumes of web data.
