Jackie Chan

It should come as no surprise that the martial artist refuses a stunt double, given that the actor is fully trained in the art of combat.

One of his most shocking stunts occurred in the 1985 film ‘Police Story’, where Chan threw himself onto a metal pole, slid down it as it exploded and shattered through a pane of glass.

He recalled: "Somehow I managed to survive with a collection of ugly bruises... and second-degree burns on the skin of my fingers and palms."
