“Visionary” barely begins to describe this masterpiece of Chinese cinema and martial arts moviemaking. A Touch of Zen (Xia nu) by King Hu depicts the journey of Yang, a fugitive noblewoman in disguise who seeks refuge in a remote, and allegedly haunted, village. The sanctuary she and her three companions find with a shy scholar is shattered when a nefarious swordsman uncovers her identity, pitting the five against legions of blade-wielding opponents. At once a wuxia film, the tale of a spiritual quest, and a study in human nature, A Touch of Zen is an unparalleled work in Hu’s formidable career and an epic of the highest order, characterized by breathtaking action choreography, stunning widescreen landscapes, and innovative editing.
