The other movie to watch besides "her" is https://www.themoviedb.org/movie/152795-the-congress The Congress (2013) Based on Stanisław Lem's novel "The Futurological Congress." Robin Wright, who plays a fictionalized version of herself, facing dwindling career prospects, agrees to sell the rights to her digital likeness to a film studio, allowing them to use a computer-generated version of her in perpetuity.

But the big reveal here: actors don't even need to sell this. AI will just take it and claim well it's different enough. In fact, if you are a B or C celebrity you might have your agent get you a million dollars or so for these rights during this grey period. Go ahead and take the million because a few years from now the price will be zero.
