According to Wikipedia, of 13 new US-made WW2-themed war movies for 2014, only one is about fighting Japan. In fact, Wikipedia tallies 41 of these US-made or co-produced WW2-themed productions since the year 2000 that deal with Germany but only 12 with Japan.
No film industry association I contacted (guilds, AFI, the Oscars' academy), nor two LA Times entertainment editors, nor the German Film Institute, has replied to my query. Not even the principal producer of last year's HBO series "The Pacific".
My dad and uncles all fought Japan and would wonder about the disparity. Now I'm wondering.
