Newswise — Realistic human bodies created by computers already travel naturally across movie and game screens, but computer graphics have yet to conquer the human countenance, and synthetic faces on the big screen have been more odd than realistic. The phenomenon that makes the illusion break down has been called the Uncanny Valley. That valley may be about to be crossed, thanks to new technology. In particular, two new forms of motion capture, the process that records an actor's movements in order to animate a computer creation, may make the difference, and soon Marilyn Monroe may play opposite Johnny Depp.

The issues, however, are not just technical; art and legal rights come into play. Author Eric Pavey discusses the new "face" of computer graphics, explains the technology, and explores the artistic and legal considerations.
