The Wan-go H.C. Weng film collection (翁萬戈影視收藏) consists of motion picture film materials from the collection of Weng Wango (1918-2020), the noted art historian, art collector, and filmmaker. The collection consists of approximately 739 individual film elements, almost all 16mm, dating from circa 1944 to 1980. In addition to the 16mm film, there are three 35mm films and 28 1/4-inch open-reel audiotapes. The materials in the collection primarily relate to films produced by Weng, including series of films on Chinese history, Chinese cities and towns, and Chinese art. The collection also includes materials were collected by Weng but were, presumably, owned by him or his production company. Included in the collection are a wide variety of different types of film elements, including original film, master picture and sound elements, projection prints, work prints, trims, and outs. While some of Weng's films have been made available through various avenues, including the educational film distribution circuit, DVDs, and online, this is almost certainly the most complete collection of Weng's work, containing master and original materials for many of his films.
