Synthespian

A virtual human or digital clone is the creation or re-creation of a human being in image and voice using computer-generated imagery and sound, that is often indistinguishable from the real actor. This idea was first portrayed in the 1981 film Looker, wherein models had their bodies scanned digitally to create 3D computer generated images of the models, and then animating said images for use in TV commercials. Two 1992 books used this concept: "Fools" by Pat Cadigan, and Et Tu, Babe by Mark Leyner.

In general, virtual humans employed in movies are known as synthespians, virtual actors, vactors, cyberstars, or "silicentric" actors. There are several legal ramifications for the digital cloning of human actors, relating to copyright and personality rights. People who have already been digitally cloned as simulations include Bill Clinton, Marilyn Monroe, Fred Astaire, Ed Sullivan, Elvis Presley, Bruce Lee, Audrey Hepburn, Anna Marie Goddard, and George Burns. Ironically, data sets of Arnold Schwarzenegger for the creation of a virtual Arnold (head, at least) have already been made.

The name "Schwarzeneggerization" comes from the 1992 book Et Tu, Babe by Mark Leyner. In one scene, on pages 50–51, a character asks the shop assistant at a video store to have Arnold Schwarzenegger digitally substituted for existing actors into various works, including (amongst others) Rain Man (to replace both Tom Cruise and Dustin Hoffman), My Fair Lady (to replace Rex Harrison), Amadeus (to replace F. Murray Abraham), The Diary of Anne Frank (as Anne Frank), Gandhi (to replace Ben Kingsley), and It's a Wonderful Life (to replace James Stewart). Schwarzeneggerization is the name that Leyner gives to this process. Only 10 years later, Schwarzeneggerization was close to being reality.
