Disney’s legal threat follows criticism from other organisations in Hollywood over the Seedance platform.
The Motion Picture Association, which represents major US studios like Warner Bros Discovery, Paramount and Netflix, has demanded that the tool “immediately cease its infringing activity”.
Actors’ union Sag-Aftra has also accused Seedance of “blatant infringement”.
Meanwhile the Japanese government has launched an investigation into the Chinese firm over potential copyright violations, after AI-generated videos of popular Japanese anime characters showed up on online.
Other AI image‑generation tools have likewise been hit with legal action.
Last year, Disney and NBCUniversal sued AI image generator Midjourney, accusing the platform of generating “endless unauthorised copies” of the studios’ copyrighted works. The case is ongoing.
Disney has also asked Google to restrict the generation of its characters on Google’s AI platforms.
