I respect that many like Pearl Harbor with Ben Afleck though I think it was a terrible abuse of history. Tora, Tora, Tora beats it hands down.
I agree with Memphis Belle, being a Tennessean and all. I would throw in 12 O'clock high is a must. I would also go with Flying Leathernecks with John Wayne.
12 O'clock High with Gregory Peck has some tremendous lessons in leadership, on a very serious level.
