High Quality Content by WIKIPEDIA articles! 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. The process of creating such a virtual human on film, substituting for an existing actor, is known, after a 1992 book, as Schwarzeneggerization, and 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, 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.
