I "facilitated" a Command Excellence Seminar during the last couple of years (1990-91) I served in the Naval Reserve and we used the film as a leadership training tool. Besides being a marvelous movie, the film depicts some important truths about leadership and Command Excellence.
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!).
