What's Inside?
- Warner Bros. sent a cease and desist letter accusing ByteDance of deliberate copyrighted character infringement through Seedance platform today.
- Seedance 2.0 users created viral videos featuring Superman, Batman, and alternate Game of Thrones scenes without studio approval online widely.
- Disney, Paramount, and SAG-AFTRA joined industry backlash, warning AI tools must respect intellectual property and actor likeness rights globally now.
The battle between Hollywood and artificial intelligence took a sharper turn this week, as Warner Bros. accused ByteDance of crossing a serious line. At the center of the dispute is Seedance 2.0, ByteDance’s new AI video generator, which has quickly flooded social media with slick clips featuring some of the most recognizable characters in entertainment. For Warner Bros., this is not about fan creativity. It is about control, ownership, and the future of storytelling itself. The studio’s legal team made it clear they believe their intellectual property was built into the tool from the start, without permission.
Warner Bros. Calls Out ByteDance over Built-in Character Access

Warner Bros. did not mince words in its letter. Wayne Smith, the studio’s executive vice president of legal, pointed directly at the platform’s design. “The users are not the ones at the root cause of the infringement,” Wayne Smith, EVP of legal at Warner Bros., wrote in a letter to the Chinese company. “They are merely building on the foundation of infringement already laid by ByteDance as Seedance comes pre-loaded with Warner Bros. Discovery’s copyrighted characters. That was a deliberate design choice by ByteDance.”
Smith’s message carried an added layer of personal weight. He addressed ByteDance’s legal chief, John Rogovin, who once held the same role at Warner Bros. and helped protect those very properties. “ByteDance is now engaged in blatant infringement of the very same properties you spent many years protecting,” Smith wrote.
The frustration is easy to understand. Seedance users have generated convincing videos featuring Superman, Batman, and even alternate scenes from Game of Thrones. Other viral clips include imagined clashes and crossover moments that studios never approved. Warner Bros. insists the problem goes beyond fans experimenting. It believes the tool itself enables the misuse.
Warner Bros. Questions Why Safeguards Came Only after Backlash

ByteDance, which also owns TikTok, has promised action. The company said it would introduce safeguards to prevent unauthorized use. Still, Warner Bros. remains skeptical about the timing.
“While this is a promising indication that we may resolve this dispute business to business, it nonetheless begs the question why guardrails that can so quickly and easily be implemented were not present upon Seedance’s release,” the letter stated.
Warner Bros. is not alone. Disney and Paramount have already sent their own cease-and-desist letters. Industry groups like the Motion Picture Association and SAG-AFTRA also raised alarms, especially over AI recreating actors’ likeness without consent.
For Hollywood, the stakes could not be higher. These characters are more than content. They are the foundation of billion-dollar franchises and decades of creative work.
Seedance 2.0 may represent a leap in technology. But Warner Bros. and its peers are sending a clear signal. Innovation cannot come at the cost of ownership. And this fight, still in its early days, could shape how AI and entertainment coexist for years to come.
