INSTINCT (R, 126 minutes)Acted with energy and put together with every slick Hollywood trick up its hairy gorilla-suit sleeve, "Instinct" could transfix teens interested in conservation issues and others hungry for character-driven drama in which the actors actually show emotion. Only later, perhaps when discussing the film in a history or social studies class, will they note that according to the myopic worldview in "Instinct," the biggest horror to occur in Rwanda in recent years wasn't genocide but the tragic killing of mountain gorillas.

A relatively mild R-rated film, suitable for most teens, "Instinct" does contain frequent profanity and several moments of loud, intense -- though fairly bloodless -- violence, including the shooting of gorillas (actors in suits) and the poignant close-up death of one. Grim scenes in a psychiatric prison could upset some.

Anthony Hopkins plays a famed primatologist who, before the film begins, went missing in Rwanda while studying the mountain gorillas. When Rwandan park rangers found him, he killed them. Transferred from a Rwandan prison to a psychiatric penitentiary in Florida, he has long refused to speak. Cuba Gooding Jr. plays an ambitious psychiatric resident who tries to get through to him, and maybe write a book about the case. He learns humility instead.

XIU XIU THE SENT DOWN GIRL (R, 99 minutes)A heart-rending and visually striking fable about a girl whose life is ruined by the Cultural Revolution in Mao's China, "Xiu Xiu" isn't appropriate for any but the most mature high-schoolers because of its explicit and upsetting sexual content. For them, however, it would provide not only a fine way to begin a habit of attending foreign films, but also a poetic rather than historic insight into the upheaval in China in the 1960s. The rating covers graphic sexual situations and semi-nudity, out-of-wedlock pregnancy and bloody sheets after an abortion or miscarriage.

Directed by Chinese-born but U.S.-based actress Joan Chen, "Xiu Xiu" tells the story of a pretty young teen (Lu Lu) who leaves her family in the big city and is "sent down" by the leaders of the Cultural Revolution to lose her urban ways and learn horse tending in Tibet. She's assigned as apprentice to a nomadic horse herder named Lao Jin (Tibetan actor Lopsang), living in his tent on the vast tundra. He's a kindly man who respects her privacy and chastity.

When Xiu Xiu is unable to get bureaucratic permission to go home to her family, she begins to give her body to a string of brutish men, all of whom promise to pull strings on her behalf, but never do. Lao Jin cannot stop her self-destruction and eventually commits a desperate act to save her. An achingly beautiful tale about the power of love and the human tragedy created by oppressive governments, "Xiu Xiu" was shot without permission on the border between Tibet and China.
