Netflix has grown tired of AI remixing its hit shows. The streaming giant this week sent a cease-and-desist letter to ByteDance, accusing its AI video model Seedance 2.0 of copying characters, costumes, and scenes without permission.
ByteDance, the Chinese tech company that owns TikTok, now faces mounting pressure from some of Hollywood’s most powerful studios over what they describe as widespread intellectual property violations. The confrontation marks a new phase in the entertainment industry’s battle with generative AI.
As video models become more realistic and widely accessible, studios argue their copyrighted content is being used to train and power commercial AI systems that can produce detailed elements of their most valuable franchises. Several major companies have now threatened legal action, signaling that the debate over AI-generated video is quickly shifting from discussion to enforcement.
Netflix threatens litigation
Business Insider reported that Netflix sent a two-page letter on Tuesday night describing Seedance as a “high-speed piracy engine.” The letter was signed by Director of Litigation Mindy LeMoine and accused ByteDance of engaging in “pervasive and willful unauthorized reproduction of Netflix’s valuable intellectual property.”
“Netflix has never authorized ByteDance to use our content to generate these images or videos,” LeMoine wrote. “The use of copyrighted works to create a competing commercial product, especially one that regurgitates the original, is not protected by fair use,” LeMoine added.
To avoid immediate litigation, Netflix demanded that ByteDance cease generating content that resembles its properties, purge Netflix-owned content from its training data and platforms, account for all related infringements, and revoke third-party access to the tool. The company gave ByteDance three business days to respond, according to Business Insider.
The Los Angeles Times noted that Seedance videos have flooded social media in recent days, including fabricated fight scenes featuring figures resembling Tom Cruise and Brad Pitt.
Some fans were also using the AI video generator to create alternate endings for shows like Game of Thrones and Stranger Things. Industry guilds, including SAG-AFTRA and the Motion Picture Association, have criticized the AI platform.
Hollywood unites as legal pressure builds
Netflix joins Warner Bros. Discovery, Paramount, and Disney in sending cease-and-desist letters to ByteDance, arguing that the AI system appears to have been trained on copyrighted material without authorization.
The Los Angeles Times stated that Disney accused ByteDance of loading Seedance “with a pirated library of Disney’s copyrighted characters from Star Wars, Marvel, and other Disney franchises.”
Warner Bros. Discovery similarly described the AI outputs as blatant infringement of its properties.
ByteDance told the BBC that the company “respects intellectual property rights, and we have heard the concerns regarding Seedance 2.0.”
“We are taking steps to strengthen current safeguards as we work to prevent the unauthorized use of intellectual property and likeness by users,” ByteDance’s spokesperson emphasized.
The Los Angeles Times also reported that Dan Purcell, chief executive of Midnight Labs, said these letters might be a delayed reaction from the studios.
“Once synthetic content is generated, it spreads instantly and at a massive scale. By the time lawyers engage, the damage is done,” Purcell said in a statement.
As ByteDance weighs its response, the standoff underscores how quickly generative AI has become a tipping point between Silicon Valley innovation and Hollywood’s copyright protections.
