This supplemental featurette is not about the Sun Tzu book. It instead features cast and crew of 'The Patriot' (2000) discussing how war was fought in the period of the American revolution and how that style of warfare was recreated for the film, including practical construction and digital support effects, the actors' work in the fighting scenes, and more....
The story also happened to the lead actor in real life, feel sad that human nature still has not changed. All casts are good, in particular the male lead's acting is excellent! Movie is well made, each main character has their own song, music style reflects chinese music's elegance, strongly recommend!
