This is an amazing film about what it truly means to be "unfit for command". His "unit for command" character volunteers to lead a demolition team of 7 other men in war torn, famine torn China during World War II, in an attempt to slow down the advance of the Japanese.
And it is of the utmost relevance now in 2020, and has been for at least 40 years.
James Stewart plays a man much younger than the actor himself, and you can tell, by the very ignorance and self righteousness of the character he plays. The supporting cast is as excellent as Stewart is. The most recognizable ones are Morgan, Best, and Corbett. Morgan and Best are best known as fairly macho character actors, and Corbett as a potential leading man. Here, Corbett is the interpreter for Stewart. Accompanying the team are a Chinese colonel and the wife of a general who are on their way to the final destination. Fortunately, the colonel also has some soldiers helping.
Stewart does a remarkable job in playing what can only be called a villain. There are many examples of actors portraying villains so realistically that they snake oil their way into making naïve people think their motivations aren't pure evil. Heflin in "Gunman's Walk", Eastwood in many Westerns, March in "Hombre", and others. Sometimes, these human monsters are misinterpreted by naïve viewers as actually being "heroes", but there is no way that they are.
The major (Stewart) makes about every wrong decision a man can make, and it is obvious to any educated person. His college education only helps him to be a human monster. The major does a good job of seeming to care, but he doesn't, or he wouldn't squander human lives the way he does, nor fail to foresee problems that anyone with his educated would foresee, even in 1944.
Sure, there could be some failure to understand Chinese culture, but the fact is that the major is "totally out of control to demons inside" and is "unfit for command". That, in essence, is the film. And it is portrayed with excellence. It should be rated "R" for mature audiences, because only mature viewers can understand what it truly means.
There are lessons here. America, certainly for the past 40 or 50 years, has had too many people in authority, and too many voters, and too many jury members, who reward "unfit for command" personality and character. Too many Americans "blame the victim, never the criminal". That is what Western culture deteriorated into.
The film also shows the need for Western culture to go back to respected elders, people with experience and savvy, over the young "unfit for command", "upwardly mobile" "mob family member" sorts who are so loved by the ignorant masses, be they theists, atheists, materialists, karma lovers, whatever they are, the connecting link is "arrogance", in believing that some people are demigods, and some are cannon fodder.
It is because of this belief and arrogance that certain leaders in the U.S. are in the position they are in, and that means both Republicans and Democrats.
This film gives a clear picture of that. It should not be misunderstood as a film that sanctions or excuses or pardons the major, nor as one that actually gives him any natural motivation, but as one that clearly depicts his actions as being out of control to demonic forces (or, if you're a materialist, to chemical forces). And the need to keep such human monsters from being in positions of stewardship.
