This is an overlooked gem that I only heard about by happenstance. It's older and campy, but it's always a treat to watch Jimmy Stewart's performances. It's a little-told part of American history, which is always fun, but the style is certainly dated. The diplomatic language was exquisite and cut so brilliantly to the heart of each conflict in question that it almost bumped it up to a 4/5 for me by itself. All told, though, at the very least it could use a non-gritty remake with an emphasis on dialogue.
