A stunt double is a professional performer who takes the place of an actor during dangerous or physically demanding scenes in movies and television shows. They are trained in various skills, such as martial arts, gymnastics, and high falls, to safely execute stunts that may be too risky for the main actor. This helps ensure the safety of the cast while still delivering exciting action sequences. Stunt doubles often resemble the actors they stand in for, allowing for seamless transitions between shots. They work closely with directors and choreographers to create realistic and thrilling scenes. Many well-known films, including those in the Marvel Cinematic Universe and James Bond series, utilize stunt doubles to enhance their action sequences.
