I have spent my life making documentary films. Some of my mentors, men I have worked for, like Denis Mitchell, are now appreciated only by film historians, while others, like Studs Terkel, are better known. For over half a century I have seen some of the most amazing technical and aesthetic innovations in the area of documentary film and video. I feel as if I have seen the industry move from the stone age of production technology to the digital space age in the span of one lifetime.
