Hollywood heavyweight Warner Bros. has taken the artificial intelligence company Midjourney to court. The entertainment giant claims Midjourney is generating and sharing images of its famous characters without permission. This legal action targets Midjourney for allegedly reproducing and distributing images of beloved figures like Superman, Batman, and others.
The lawsuit landed in a federal court in Los Angeles. Warner Bros. argues that Midjourney used illegal copies of their material to train its AI system. The company points to examples such as Bugs Bunny, Wonder Woman, Scooby-Doo, and the Powerpuff Girls. These images, Warner Bros. says, are being widely circulated online.
Court documents, reviewed by various news outlets, highlight Midjourney’s service. It lets millions of subscribers create detailed visuals of copyrighted characters. Warner Bros. states these results accurately copy works from its catalog, which amounts to copyright infringement.
Serious Infringement Claims
The legal complaint states Midjourney built its AI model using "illegal copies" of Warner Bros. content. It also claims Midjourney encouraged users to make images and videos of these characters "in all kinds of scenarios." Even a simple command like "classic comic book superhero battle" can produce polished pictures of DC Studios characters, including Superman, Batman, and Flash.
Warner Bros. emphasized its view that Midjourney "believes it is above the law." The company suggested Midjourney could easily stop this behavior, just as it restricts content involving violence or nudity. The studio believes Midjourney’s actions confuse customers about what is legal. They claim Midjourney misleads subscribers into thinking that the widespread copying and resulting images have approval from Warner Bros. Discovery.
The studio is seeking significant damages. It could demand up to $150,000 for each infringed work. These large figures send a clear message about the seriousness of the dispute. They also highlight the high value of intellectual property in the entertainment business.
Prior Lawsuits from Disney and Universal
Warner Bros.’s lawsuit is not a standalone event. Other major studios, like Walt Disney and Comcast’s Universal, have filed similar lawsuits against Midjourney. These earlier cases described the platform as a "bottomless pit of plagiarism." They accused it of feeding off globally recognized characters.
Disney and Universal’s lawsuit, also in a Los Angeles court, gave specific examples. These included Darth Vader from Star Wars, Elsa from Frozen, and the Minions from Despicable Me. Executives from these companies stressed their goal to protect artists’ work and the large investments made in their content catalogs. Horacio Gutiérrez, Disney’s Executive Vice President and Chief Legal Officer, said the company sees potential in AI as a creative tool. However, he stressed that "piracy is piracy," no matter the technology used. Kim Harris, Executive Vice President and General Counsel for NBCUniversal, added that they aim to protect the work of those who create inspiring content for millions.
Midjourney’s Side of the Story
Midjourney maintains that its system needed to be trained on "billions of publicly available images." This process, they argue, was necessary to learn visual ideas and link them to language. In court papers filed in August, the company argued this process is "transformative fair use." They say recent rulings in similar cases against other AI companies support this defense.
Midjourney also states that its customers must follow the terms of use, which forbid infringing intellectual property rights. David Holz, Midjourney’s founder, likened the tool to a search engine in a 2022 interview. He said it learns from images on the web. Holz added that AI, like a person, can observe and reinterpret existing works. This case joins a growing global discussion about the legal and ethical limits of training AI models with protected material. This debate will likely shape the relationship between technology and the cultural industry for years to come.
