TL;DR  —  ONE-LINE SUMMARY

Studios have stopped watching from the sidelines: Disney and Warner Bros. are now suing Midjourney over AI-generated output that reproduces recognizable characters — not because of what AI trained on, but because of what it spits out. The lawsuits, ByteDance's viral deepfake scandal, and Disney's exit from its OpenAI deal are collectively drawing the first real legal boundary around IP reproduction in generative AI — and that boundary will reshape every content-tech partnership deal on the planet.

The Long Hesitation Is Over

For years, major Hollywood studios refused to sue AI companies. The reasons were pragmatic: litigation is expensive, copyright law for AI was unsettled, and — above all — studios did not want to permanently close the door on potential AI partnerships before those relationships had even begun. Even when the Writers Guild of America sent formal letters urging studios to take legal action over the use of Hollywood screenplays in AI training, the majors held back.
