A stunt double is a cross between a body double and a stunt performer, specifically a skilled replacement used for dangerous film or video sequences, in movies and television (such as jumping out of a building, jumping from vehicle to vehicle, or other similar actions), and for other sophisticated stunts (especially fight scenes). Stunt doubles may be used in cases where an actor's physical condition precludes much activity (such as when the actor is too old to perform extended dubs choreography), or when an actor is contractually prohibited from taking certain risks. Stunt doubles are sometimes referred to as "stunties".
The terms stunt double and body double may be used interchangeably for cases where special skills (sometimes far from dangerous) are needed, such as dancing (dance double), playing the piano, or competitive skiing. Stunt doubles should be distinguished from daredevils, who perform stunts for the sake of the stunt alone, often as a career. Sequences often do not place stunt doubles in the same mortal peril as the characters: for example, harnesses and wires can be digitally edited out of the final film.
Many stunt doubles have long production careers as part of a star actor's contractual "support crew" along with the star's cooks, trainers, dressers, and assistants. Often stunt doubles have to look like their respective actors, in order to keep the character's appearance. Stunt doubles for Eddie Murphy, John Wayne, Harrison Ford, Steve Martin, Salman Khan and Michael Landon have been associated with their lead actors for decades.
