Screening Room was a 1970s Boston television series that invited independent filmmakers to show and discuss their work on a commercial (ABC-TV) affiliate station. This unique program, developed and hosted by filmmaker Robert Gardner, dealt even-handedly with animation, documentary, and experimental film, welcoming such artists as Jean Rouch, Jonas Mekas, Stan Brakhage*, Hollis Frampton, Yvonne Rainer, and Michael Snow. Frequently, guests such as Octavio Paz, Stanley Cavell and Rudolph Arnheim appeared as well. The filmmakers presented on the show are now considered the most influential contributors to their respective genres and the footage is invaluable for students, scholars and lovers of film.
