Stunt performers, also described as "stuntmen" or "stunt doubles", appear in films in place of the featured actors during times when the film script requires an action scene. In those instances, the stunt performer is dressed in clothes similar to the main actor, and carries out sequences like falls, jumps, high speed driving and other acts that run the risk of injury. Various techniques are used to make it less obvious that a stunt double is appearing on the screen in place of the regular actor, including filming from a distance, avoiding shots where the stuntman's face can be seen, and displaying the stunt on screen for only a few seconds.
