To find the perfect villain for 2004's "Sky Captain and the World of Tomorrow" director Kerry Conran chose to use one of the most famous actors of all time, Laurence Olivier.
There was only one problem: Olivier had been dead for 15 years.
The film's star, Jude Law, told USA Today, filmmakers chose to go with Olivier because few actors — alive or dead — carried the fearsome weight of the famed British actor.
To pull this off, the production recorded new dialogue by another actor and used archive footage to create the evil hologram, Dr. Totenkopf.
