I remember "A walk in the Sun", great movie, I haven't seen it for the longest time. Think, I'll try to find it at the local blockbusters.
I also remember a movie called "Go for Broke!" starring Van Johnson, it was about the Nisei (American born Japanese) in the 442nd Regimental
Combat Team. They served in the European theater of operations, and became the most decorated American unit in WW2.
There was a funny line in the movie, I think it went like this: Van Johnsons' character a Lieutenant reading a list of new
replacements says: "O'Hara, finally a good Irish lad!" it turns out the replacement was a Japanese-American kid named
Ohara.
and another one where a German officer asks his American captor: What kind of troops are these, Chinese?
The Van Johnson character reply's: "Japanese. Didn't Hitler tell you? Japan surrendered. They're fighting on our side now.
