I was in a store a while back and they had a large TV turned on to a football game. It took me a few minutes to realize that the image was not of a real game but a computer generated image of a game.
There may come a day when you (the viewer) could pick and choose which actors you want to watch in a movie. Or, perhaps even put yourself in a movie. Going even further, allow the viewer to choose dialog and determine how the movie ends.
Technology changes everything and the GOLDEN AGE of Hollywood will finally come to an end.
A setup where you could make and rework favorite shows and movies with CGI actors and all would be great.
