The horror genre has a long tradition of trilogy films, and this 2004 feature collects macabre tales by three notable Asian directors. “Dumplings,” directed by Fruit Chan of Hong Kong, is a fairly corny vignette about a cook (Bai Ling) whose delectable dumplings are filled with diced human fetuses. The other two are well worth seeing: “Box,” an eerie tale of sibling rivalry by Japan’s Takashi Miike (Audition), and “Cut,” a white-knuckle hostage drama about a film director menaced by a disgruntled extra, written and directed by South Korea’s Chan-wook Park (Oldboy). In Korean, Japanese, Mandarin, and Cantonese with subtitles. R, 118 min.
