It’s not a huge threat to the movie and tv industry yet, but it could be soon, from writing scripts, to using actors voices and then likenesses, then eventually crafting scenes and episodes based entirely on prompts and AI its probably only a matter of time, unless regulation and Unions stand in the way.
It’s worth noting too that the games industry these days is bigger than movies, so I think this situation is a good thing for SAG AFRA to stand firm on.
