Critical reviews of more than 600 environmental films selected from a field of several thousand are contained in this reference guide. Designed to provide a comprehensive selection of films covering all aspects of environmental affairs, from air pollution to wildlife, the guide is primarily user-oriented. It consists of two parts: a Review Section, which contains film reviews according to the 21 subject categories in the ACCESS system; and an Index Section, which permits location of films by subject, industry, sponsor, and title. Each review provides title of the production, physical characteristics, date, sponsor, producer and/or distributor, intended audience, cross referencing numbers, and rating followed by a synopsis of content, treatment, and ecological objectivity. The end result is a pattern of different subjects, treatment, and styles, ranging from cartoons and TV documentaries to surrealist/impressionist pieces and lecture-type fare. Summary comments indicate that most films take a finger-pointing problem approach with an emotional commentary; few illuminate the root causes of pollution, explore alternatives, and examine solutions. Progress by the film industry, therefore, is needed in providing such education about the legal, technical, political and economic complexities of the problems. (BL)
