You will be able to replace anything or anyone or any voice from old movie to new one day. You will be able to 'photoshop' the writing, set, actors, voices for those actors. Now here is the other thing. You will be able to take pictures and put anyone into the movie. If you think about that a moment......that is really creepy. Kids will take pics of boys and girls at school and make fantasies with them. Children. Old pics of you online. Catfishing and fake music are nothing. This is going to go deep into making things truly uncanny for everyone. Now, imagine actors and models selling rights to let you make movies and put them in it. I don't mean famous people. I mean poor actors and actresses. A cottage industry. Like Onlyfans but you put them into your movie. You would just have a list of stuff they say you can't have them do or done to them. (Sex, murder, etc) Now, imagine remaking Sinatra's old movies and some moron puts in anime girls with Samuel Jackson's voice. You may not be able to profit from it. But you may be able to share it....then Samuel Jackson gets a check for voice acting in your movie. There are going to be so many laws and lawsuits and crazy stuff in the next few years. Here is the thing. You may not be able to use their likeness here but what about somewhere else in the world? What happens when young people see themselves online in porn thy were never in. It is coming.
