My interest in the movie came largely from just such a course that I attended at about the same time (91-92, a one-week residential leadership course for state agency senior managers in Texas).
I wore out a videotape of the movie after that, and got the DVD as soon as it was released. I drove my wife crazy, explaining the leadership transitions to her as we watched the movie (I still have the graphical Leadership chart in 8 1/2 x 11 color!).
I still have my Command Excellence Instructor materials, and still usem FRom time to time.
I need to get the DVD -- my tape is just about worn out, also!
