Brian Regan: I Walked on the Moon

See the world's legendary fighting styles in an entirely new way. As young martial artists Mike Chaturantabut and Matt Mullins fight their way through the world's most prestigious tournament, East meets West in a stunning application of visual technologies and the biomechanical secrets behind the world's martial arts are revealed for the first time. Using a unique graphic technique that allows for "in-the-body" animation of joints and muscles, experts demonstrate the basic principles behind muscular torque and leverage - creating fighting and sparring scenes unlike anything you've ever seen. Weapon masters showcase the physics behind the fiercest weapon styles - the twin broadswords, the Chinese straight sword and the Katana - and demonstrate how warriors can quickly master even common household items - like a traditional Japanese hand fan - to devastate their opponents.

From China’s wild west to Beijing’s boom, photography and filmmaking duo Jeff and Peter Hutchens capture china in its moment of change.
