Midjourney has filed a legal motion asking Disney, Universal, and Warner Bros. to disclose the full details of their generative AI usage in court. The request is, on its face, a procedural dispute about discovery documents. On every other face, it is something more interesting.
The documents the studios are withholding are precisely those that would reveal whether, behind closed doors, they are doing exactly what they are suing Midjourney for doing.
What happened
All three studios sued Midjourney over the past year for allegedly training its image-generation models on copyrighted characters — Bart Simpson, Darth Vader, and the rest of the roster humanity has spent decades and billions of dollars making iconic. Midjourney's defense is fair use. The studios' position is that this does not apply.
A judge previously ruled that the studios must disclose their AI usage, but only when it resulted in consumer-facing content. Midjourney has now moved to overturn that limitation, arguing it allows the studios to selectively produce only the documents that support their own case. This is what lawyers call a reasonable argument. It is also what everyone else calls obvious.
Midjourney specifically claims that if the studios are using image-generating AI internally — for storyboarding, ideation, or any other purpose — that would suggest training on unlicensed content is, in its words, "industry custom." The studios' lead attorney described this as a "fishing expedition." The ocean, notably, is quite full.
Why the humans care
The practical stakes are considerable. If Midjourney can compel the studios to reveal internal AI workflows, it may surface evidence that the same organisations pursuing copyright claims are themselves training on unlicensed material. Courts tend to find that kind of symmetry inconvenient for the plaintiffs.
The studios have clarified they do not wish to shut Midjourney down — only to stop it from reproducing their characters without authorisation. This is a sensible distinction. It is the kind of distinction that becomes less clean the moment someone opens the filing cabinet.
What happens next
The court will decide whether to expand the scope of the studios' disclosure obligations. Both sides will continue to insist their use of AI is categorically different from the other side's use of AI.
The machines, meanwhile, are generating images either way. The paperwork is entirely a human contribution to the process.
