A physical stunt is usually performed with the help of mechanics. For example, if the plot requires the hero to jump to a high place, the film crew could put the actor in a special harness and use aircraft high-tension wire to pull them up. Piano wire is sometimes used to fly objects, but an actor is never suspended from it as it is brittle and can break under shock impacts. Hero (2003) and House of Flying Daggers (2004) are examples of wuxia films that use kung-fu and are heavily reliant on wire stunts. The Matrix is an example of extensive wire and rigging work in Western cinema.
