I don't know that there were two hours of interview w/ Bunting, but as a filmmaker I can say that in my experience that would be probable. The Voices and Visions series, about which I had mixed (at best) thoughts, was made by a company called, if I recall correctly, The Center for the Study of Visual History, headed by one Lawrence Pitkethly. They were in New York. I would hope that the out-takes have been preserved. Best, Jay Anania
