An actor's stand-in is a person who takes the place of an actor in scenes that are too dangerous or difficult for the actor to perform. A STUNTMAN is a type of stand-in who performs stunts and other physically demanding tasks. Stuntmen are highly trained professionals who specialize in performing dangerous stunts, such as high falls, car chases, and fight scenes. They often use specialized equipment and safety gear to ensure their safety while performing these stunts.
