MIDJOURNEY TELLS DISNEY AND UNIVERSAL: SHOW THE COURT YOUR OWN AI BEFORE YOU COME AFTER OURS Three of the biggest entertainment studios in the world sued Midjourney in 2025 for training its image generation AI on copyrighted characters. Disney, Universal, and Warner Bros. all filed claims alleging that the AI startup had enabled massive infringement of their properties, from Bart Simpson to Batman to Darth Vader. They claimed fair use arguments do not apply when the output competes directly with the original work. Now Midjourney wants to see their homework. The company filed a motion this week asking the court to compel the studios to reveal how they use AI themselves. Midjourney’s lawyers are seeking the studios’ AI business plans, internal research reports, training datasets, model weights, and the board presentations executives used when discussing AI strategy. The argument is direct: if the studios are training AI tools on copyrighted material to build their own systems, their position as wronged parties becomes considerably more complicated. A magistrate judge had already limited what the studios had to disclose, ruling they only needed to hand over information about consumer-facing AI applications. Midjourney is now asking the presiding judge to overturn that restriction and require much broader disclosure into what is happening behind the scenes. The studios have invested heavily in AI infrastructure. What Midjourney is demanding would put that infrastructure under legal scrutiny at the exact moment every major entertainment company is trying to keep its internal AI strategy private. Whoever loses this case will help write the copyright rules everyone else has to live with.
