I saw a "making-of" special on the movie, and I still want to see it.

LH, my thoughts EXACTLY! My family listened to me splutter for an hour about how late model green A6M3 Zeros were being used INSTEAD of the earlier silver & white A6M2's.

There were 8 planes actually used for the Zeros, including the only surviving Japanese Zero. The rest were post-war replicas made in Russia.
