this inkl has another interview with lucas/cast/crew
http://www.tennessean.com/usatoday/article/52378382
sounds like it was screened for the original airmen (and the article makes note that not many are still with us) and they liked it.
I am a little bothered that lucas and co. go on and on about the original tuskegee airman and how this is all a tribute, its more important than money, etc etc. and I don't believe a lot of the behind-the-scenes anecdotes, especially those involving lucas' attempt to reach out to other studios.
Lucas is up-front saying its a corny jingoistic movie. so things are already in motion to defend it against charges that its superficial, shallow and romanticized. he mentions the 'old-time' war movies - so there's your homage to 'older, simpler movies from hollywood golden age' that the apologists love. Nowadays, war movies - any drama based on a true story for that matter - have become much more nuanced and complex beyond lucas' capabilities. He says that he wanted the movie to be more about achievements than racism - which is fine, but the trailers I saw had every racism cliche in the book.
Its interesting to note that Rick Mccallum was not featured in this interview.
