After dazzling audiences with her waifish beauty and graceful performances in a string of Chinese martial arts hits, Ziyi Zhang is coming of age as an actress on the brink of international stardom. Zhang, 26, gives her most mature performance yet with a portrayal of a prostitute struggling with her feelings in Wong Kar Wai's "2046," which had its U.S. opening last weekend, and stars in the Hollywood version of the best-selling book "Memoirs of a Geisha" due in December. Larry Fine reports for Reuters.
