Warner Bros. Sues AI Startup, Claiming It Stole Superman’s Image

Warner Bros. Discovery Inc. sued AI startup Midjourney alleging theft of its intellectual property, saying the company allowed customers to generate images and videos of characters like Wonder Woman and Superman without permission.

Midjourney, based in San Francisco, offers a subscription service that lets customers create images and clips using artificial intelligence. In the suit, Warner Bros. included pictures it said were generated by Midjourney’s technology. They include Superman looking at his cell phone and Batman posing with the Star Wars character R2-D2.
