This stunt in a word is ridiculous. I mean with all the respect in the world!
Chan jumping from a ledge and sliding down a pole fitted with lights before lading through a glass roof some forty feet below.
The sequence was filmed for the movie Police Story and was shot on fifteen different cameras and was such an incredible shot that the movie included it with three separate angles. After the scene, Chan was whisked away to another shoot before he collapsed from exhaustion.
He suffered second-degree burns on his hands and was lucky not to have been injured more severely
