Film preservationist extraordinaire Robert Gitt of the UCLA Film and Television Archive hosts a fascinating lecture on the history of sound in motion pictures. After offering this presentation for years at archival and museum gatherings Bob was persuaded totransform it into a DVD so a wider audience could enjoy it. No one knows more about this subject, and Bob has gathered an impressive array of illustrations and film excerpts. Thanks to the Rick Chace Foundation, it is available for educational purposes for a nominal $10 handling fee at this website.
