- Disney’s cease-and-desist alleges Seedance was pre‑packaged with a pirated library of Marvel and Star Wars characters, citing examples like Spider-Man, Darth Vader and Grogu.
- Paramount Skydance sent its own legal notice accusing ByteDance of blatant infringement across franchises including South Park, Star Trek and The Godfather, also naming the Seedream image tool.
- The Motion Picture Association demanded ByteDance immediately cease infringing activity, while SAG-AFTRA condemned unauthorized use of members’ voices and likenesses.
- Seedance 2.0 remains a limited rollout in China generating roughly 15-second clips, has produced viral celebrity deepfakes such as a Tom Cruise–Brad Pitt fight, and operates with undisclosed training data as ByteDance pauses some real-person upload features; Japan has opened a copyright inquiry.
