Not the Eugene O'Neill play, but a rip-roaring ride through history with two     ancient swordsmen. This thriller includes historic settings in ancient China,    promises made to dying martial arts masters, honor to be upheld, special         effects, time travel, street life in present-day Hong Kong, a little social    commentary, and, of course, good vs. evil. Starring Maggie Cheung and Yuen     Biao. Cantonese with English subtitles.                                        Fok Yiu-leung---Hong Kong---1991---114 mins.
