I think the question is will it make the story more engaging. Actors that have done CGI films in interviews are always saying wow, it's cool I won't have any work soon. However when it takes roughly 2-3 years to produce a CGI film it's a bit unrealistic that the digital clones will be taking over acting jobs. There are several Japanesse 'actors' that are digital characters, they have licencing agreements through an agent, commercials, TV spots, music CDs just like real flesh people. SO it is sort of happening just not on a large scale yet. Shrek, Final Fantasy (bad script cool CGI), Finding Nemo, Lord Of The Rings, etc use the CGI to enhance the story and there may be more of that. I don't think I would sit through a CGI summer teen love story flick unless is was a fantasy setting or SCI FI that regular actors just could not perform in. Treasure Planet could be an example, I do not think that would have worked near as well with real humans on bluescreen with CGI but that's me. Closer and closer, few more years I'm sure more and more will show up but I still think that stories will drive the medium and the technology will be used to enhance that. Simone with Al Pachino is a great movie on the subject and th ethics of dealin with it all. Even has a button in the movie called "Mimic" which I thought was cute.
