How about if the production company that made "Her" wants to make "Her 2". SJ declines the voice work. Are they not allowed to hire A to do the voice work? They ask SJ again but she still declines. They make the movie with A. Was it bad form?
Just trying to figure out where people would draw the line.
Presumably, the production company and Scarlet Johansson would have it in their contract what to do in case she doesn’t want to act in a sequel.
No contract exists between OpenAI and Scarlet Johansson.
Actors don't work in films without detailed contracts, so the normal rules don't necessarily apply in that situation. The producers of Her might have the right to use SJ's likeness in related material. In any case, if they made another movie with a soundalike, the soundalike would be credited and not just called "A", so there would be no confusion about whose voice it was.
