Look at this little nugget I came across recently:

“As digital effects grow more sophisticated, we are nearing the on-screen moment at which the line between what is real and what is virtual disappears, when you can’t tell by looking whether what you are watching is an actor acting on location or a piece of software running through its program.

… What will become of our stars in the age of digital actors? … For that matter, what will become of us when we can no longer believe what our eyes tell us that are seeing?”
