Based on anthropologist Dian Fossey's autobiography, and an article by Harold T. P. Hayes, GORILLAS IN THE MIST is a portrait of the determined woman who will do anything to save the mountain gorillas that she studies, and for whose well-being she has a passionate commitment. In the process, she draws international attention to their declining population, yet her obsessive work to save them also eclipses her personal life and brings her into ruinous confrontation with relentless, impoverished poachers. At times recalling Joseph Conrad's HEART OF DARKNESS, the film touches on both Fossey's nobility--and inhumanity. To capture her passion, and the sublime African landscape, director Michael Apted shot on location in Rwanda, where the anthropologist lived and worked. Sigourney Weaver, playing Fossey, gives an intense portrayal (garnering an Academy Award nomination) of the woman who almost singlehandedly reversed the extinction of the mountain gorillas in Africa.
