That's another good Clint film. Try Two Mules for Sister Sarah. I think you'd like that too.
I just watched last night a B/W WWII film called Air Force. It was about the crew of a B-17 bomber called Mary Ann. The story begins just before the raid on Pearl Harbor, relates how they escape from Clark Field and ends with the crew listening to a briefing on how their B-17 squadron will bomb Tokyo. Well, when the movie was made, the B-29 wasn't in service yet.
There's some touching and very human moments in the movie. There's propaganda against the Japanese, too, which includes a claim that some Japanese driving a vegetable truck rammed several parked P-40s in Hickham and Clark. What's noticeable in the movie is that they keep mentioning P-40s but what is shown on the airstrips are P-39 Cobras.
