Leonid, I highly recommend you to see "Khroniki pikiruyuschego bombardirovschika" ("Dive-bomber Chronicles") or "Torpedonostsy" ("Torpedo-bombers"). The first one features real Pe-2s, and the second has IL-4s and other ACs.
The problem is that Soviet cinema aimed not on Hollywood-style special effects, but on the human relations and problems... The best Soviet movie about WWII aviation is still "V boy idut odni stariki" ("only old buddies go to combat"). It's a b/w movie with Yak-18s as La-5s, and Czech "Zlins" as 109s, but it's the most impressive film about people doing their combat job...
After a great disappointment (Pearl-Harbour) - I really want to see "Dark-Blue World". I think that European movies are very much different from American popular cinema, and expect this film to be interesting not only because of the special effects.
I hope to get this movie in a few weeks after it will be released on tape in Czech Republic. I have friends in Praha, and I hope to get a copy ASAP. Finaly Czech is not very different from Russian and I hope I can understand something
