Is it Live, Memorex...or Something More?

I've never been a big fan of CGI.

Let me clarify that. I do not believe that CGI can effectively replace the human element in film. While, with motion-capturing software, we can simulate the movements of the human body, we can create "skins" over these wire-frame models that give a very reasonable facsimile of the textures and blemishes of the human face...I have not been convinced, based on existing use, that a computer can mimic the subtle nuances of physical facial expressions to such a degree as to be believeable.

In 2002, Al Pacino starred in a fairly unknown film, Simone ("S1m0ne"), that sort of brought this point to bear. A producer, desperate for a hit and having had his star actress quit a film, finds himself in the sole possession of a piece of new technology that allows him to digitally create a synthetic actress (there's an oxymoron). The actress, Simone, becomes an overnight sensation - with a singing career to boot. She's so believable on screen, so talented - as guided by the director's technical manipulations - that everyone completely believes she is a real person, which of course causes problems for the director who has to explain why his actress is never seen in public.

I'd never really believed this could ever be possible.

Until - maybe - now.

There is a company called Image Metrics that does quite of bit of facial imagery for the gaming community. Their proprietary software does not use motion capture; instead they film an actor's face as they emote during a dialogue, digitize that face, and allow their software to analyze the nuances of the brow, eyes, and mouth movements as the person speaks. The resulting data allows them to then attach those motions to a digital character, allowing them to very accurately simulate human expressions. You can watch the promotional video here:


However. There is another video that could be potentially more mind blowing. Here is an Image Metrics spokesperson, going into more detail on the specifics of how far advanced they actually are in this process:



Once, Hollywood told us: you will believe a man can fly.

Now, maybe that man flying isn't a man at all.
