It's incredible; the lengths Jackie Chan will go through just to complete a movie. Considering most this footage is from his younger years, it's a wonder Chan has made it this far in his career! Falling from 3 stories up? Getting hit by a helicopter? Getting life threateningly injured after filming a scene and then going back and doing it again only to get injured more? It's all in the video below, which is set to a song sung by Chan himself.
