Actors, studios, agents, and the actors union SAG-AFTRA have all expressed their concerns about appearing in Sora 2's AI-generated videos ever since the deepfake machine was released last month. Now a joint statement from actor Bryan Cranston, OpenAI, the union, and others says that after videos of him appeared on Sora - one even showed him taking a selfie with Michael Jackson - the company has "strengthened guardrails" around its opt-in policy for likeness and voice.
