When it comes to stunts, not every actor is Jackie Chan<\/a> or Tom Cruise<\/a>. Most actors will require a stunt double for certain scenes, whether it\u2019s a high fall, breaking through glass, or vehicle work. Even if the actor has gone through serious and disciplined stunt training, and even in the most controlled environments, accidents can happen. Having a double can help protect star talent from injuries that could put the entire production out of commission.<\/p>\n For example, in a rooftop leap between buildings in the latest installment of\u00a0Mission: Impossible<\/em><\/a>, Tom Cruise actually breaks his ankle in the take they use for the final product. Even though he was completely rigged with wires (which were digitally removed, of course) and had rehearsed the stunt and already done several takes, the slightest change in the angle of his foot caused his ankle to break against the wall, halting production for three months.<\/p>\n
