The threat posed by AI technology to the future of filmmaking was central to last year's actor's strike, and remains a concern for the SAG-AFTRA union, which wrangled a key provision for voice actors in its latest contract.

Actors wanted to protect their likenesses and future incomes from potential abuse by Hollywood studios. The worry was that studios, which would like to spend as little money as possible making movies, would try to find ways to digitally recreate actors using CGI and then not pay the real people behind the images.
