The only problem is the "based on a true story". I was told that there is a lot of "Hollywood" in this movie, and that some of the characters are either fictional or grossly mischaracterized.
The trailers look good, though.
That's probably the case with most movies that are "based on a true story".
One in particular comes to mind of Oswald Boelcke, commander of Germany's Jasta 2 (and who was primarily responsible for starting Baron Manfred von Richthofen, aka the Red Baron, off on his distinguished but very brief career). This haunting photo shows a very young Boelcke (he was killed in a mid-air battle collision when he was only 21 or 22), so very very handsome, and so heartbreakingly young ... but with a depth of age, wisdom, ANYTHING but youth and adolescence, in his eyes and face. I have seen literally dozens of photos of these young flyers, and while many of them are handsome, not a single one is a "pretty boy."
