Tonight at the Cleveland Institute of Art Cinematheque, see two documentaries in a double feature which recounts the horror and tragedy of the Khmer Rouge in Cambodia. The first film, Golden Slumbers, playing at 7:30 p.m., tells the story of Cambodian cinema, which was evidently a unique and robust (relatively speaking) creative industry until the Khmer Rouge obliterated it when it assumed power in 1975. Some 400 films were destroyed and most of the country’s artists were systematically killed. Immediately following that film, see The Missing Picture, a foreign film Academy Award nominee which recreates a personal, untold story of genocide with the use of clay figurines. Tickets are $10 for the double feature, $7 for those under 25. (Allard)
