a WWII air battle movie about the whole eastern front and battle over berlin, concentrating on all sides, have 1 star for allieds, 1 star for LW, 1 star for russia.
swap between the stories, have the allied guy be a pony ace, LW a 190 ace (or Hartman), and the russian ace be an il2 pilot or yak pilot.
have it done in the fasion of "enemy at the gates" showing both sides (well all three sides) but not necessarily them fighting each other.
start the movie around 1943, and go forward in history until hitler dies.
it would be a 3 hour epic at least, but well worth it.
NO major CGI 500 plane battles like bravehart did with the soldiers... just good small or medium dogfights / occasional bomber escort, and attack. spend some time developing the charecters, and some flashbacks to them growing up, and show the similarities, like going hunting with their dad for the first time or something.
NO romantic interestes, except maybe an occasional flirtation with a nurse or something.
end the movie with them all old, thinking back to the war, they all survived.
maybe show the LW pilot not agreeing with the nazi agenda, and being torn between defending his country, and protesting the holocaust.
