I've just come across a six-part series documenting the art of "Jeet Kune do", the fighting style founded by Bruce Lee that has shaped the world of mixed martial arts and combat across the universe. His style, and influence in the essential, would go on to become the core of any preempted strike thrown. Narrated by Bruce himself, this documentation is truly fascinating.
