Comment: The Incredible Bread Machine

This would be my suggestion, it's an oldie but extremely good.

Here's the description:

Released in 1975 by World Research, Inc. Includes an introduction by then-Secretary of the Treasury, William E. Simon, and interviews with professors Walter Heller (University of Minnesota) and Milton Friedman (University of Chicago). Moderated by Dr. Richard Rogge (Wabash College). The film also features a cameo appearance by Murray N. Rothbard. Written by Karl Keating, Susan Love Brown, Patrea Post and Stuart Smith, based on Richard Grant's provocative poem.

The film starts a 5:10 if you want to skip the introduction (55 mins long including intro) .
