Have you ever wondered, while watching a hero teetering on the edge of a skyscraper, or a mythical monster roaring at the camera, how such wild imagination became a tangible reality before your very eyes? The truth is, we choose to be "deceived." Behind every breathtaking scene lies an army of creative minds who have mastered the art of "optical illusion." What you see as a remote island might simply be a green screen in a closed studio, and what you perceive as a giant monster could be nothing more than a mechanical puppet or a costume worn by a professional actor. Behind-the-scenes footage from the 2005 film King Kong.
