If you haven't yet seen a film by Wong Kar-wei, one of the more exciting and original of the younger Hong Kong filmmakers, you should make this immensely charming and energetic two-part comedy feature a priority; if you have, you probably won't need my recommendation. Though less ambitious than either Days of Being Wild or Ashes of Time, the Wong films that precede and follow it, Chunking Express qualifies in many ways as the most accessible of the trio and as an ideal introduction to his work. Both stories here are set in contemporary Hong Kong and deal poignantly with young policemen striving to get over unsuccessful romantic relationships and their unconventional encounters with other women--a hit woman for the mob in the first case, an infatuated fast-food waitress in the second. Wong's singular and frenetic visual style and his special feeling for lonely romantics may remind you of certain French New Wave directors, but this movie isn't any trip down memory lane; it's a vibrant commentary on young love today, packed with punch and personality. With Lin Hsing-hsia, Takeshi Kaneshiro, Tony Leung, and Faye Wong. Film Center, Art Institute, Columbus Drive at Jackson, Friday, October 28, 6:00, and Saturday, October 29, 2:00, 443-3737.
