A person who takes the place of an actor. In some cases, a double might when the shot is so long the actor is not recognizable, in order to reduce production costs. During dangerous scenes Doubles are used (Stuntman, Stuntwoman) to protect the star from injury. So called "Body Doubles" are also used when specific body parts are featured in particular during erotic scenes. There are also Stand-ins that closely resemble stars. The function of the Double is as a place holder for the actor during extended shot, scene and lighting set ups.
