He Uses Stuntmen For Unusual Reasons
Jackie Chan is well known for coordinating, as well as performing, his own stunts without fail. However, he doesn’t deny using a body double on occasions that don’t actually require any stunts. He has been known to utilize stand-ins for scenes when his character is driving, walking around, or performing any other menial tasks that don’t require Chan’s skill.
He does this in order to have an opportunity to rest and prepare for his rigorous stunts. The actor also makes sure that his stand-ins perform stunt tests so that they can synchronize their movements when in front of the camera.
