I think I'll treat this documentary more kindly than I might, if it has been more than half an hour long and if it had been made in 2013 instead of 1963.
It's a brief sketch of MacArthur's career that avoids even the hint of controversy except where it is absolutely unavoidable. He's brave, stalwart, loyal, caring, daring -- an infallible genius. The production could have been put together by MacArthur himself. It's a regular, old-fashioned flag waver.
He was of course a remarkable man, a good soldier and a brave one. He was also an actor who would have rivaled Robert Burbage. We see footage of him in World War I with his first prop, a cigarette holder. That was before the corncob pipe, the shades, and the faded field marshal's cap.
And his being fired by Truman for advocating insane political moves? "Always true to his principles, MacArthur was relieved of his command and brought home to a hero's welcome." Something like that. No mention of Nimitz or the Central Pacific, or Anacostia, his run for the presidency, or any other such nettlesome matters.
I don't mean to denigrate his accomplishments. He really WAS a splendid general until he was in his 70s. I wonder if generals have a career trajectory something like those of physicists, who achieve their victories early in their careers, rather than chess experts, who can still play tournament-level games into their 80s.
In many ways, his greatest achievement was the introduction of democracy and modern capitalism into the conquered nation of Japan, his humane treatment of its people, and his politically sensitive dealings with its emperor.
