A synthetic version of a dead actor will never be the same as the real actor. Just won't be. Ever. Technology isn't the answer to everything. What made the actor unique is missing and can't be duplicated. You can have sound alikes, and look alikes, but the heart and the mind is gone. Of course I realize in most movies you wouldn't notice the difference but once in awhile the human touch is important. And I worry that our already youth obsessed culture will get stuck on the idea that only young versions of actors should be permitted to exist...which would mean eliminating very fine older actors (of either sex) who are already denied roles in favor of callow youths, and we miss out on diversity. I, for one, want to see how Johnny Depp develops as an actor as he gets older (and will he ever change his name to "John") .... I wouldn't want him to stay at one level when it is his experience that makes his acting so intersting. I want to see Meryl Streep continue to act. I don't want every woman to be Jennifer Anniston or J Lo; and I certainly don't want every man to be Ben what's his face, or whoever the latest hunk of the moment is.
