Inspired from actual events, this William Berke's film is very unusual and interesting. It shows that in America, you have born Americans - white, not Asian - who could work for the Rising Sun evil empire. What a shock for me...I thought that only Americans from Japanese descent could, for obvious reasons. Thats' for this reason, I guess, they were all sent to camp such as Manzamar.... So, yes, what a gem this RKO movie, revealing astounding matters. Philip Ahn is of course i the cast. I am deadly sure that he played in every forties decade war film involving the Pacific front, not the European of course !!!
