I saw it when it was playing here in NYC about 2 weeks ago, it was playing in foreign/independent type theater but was only there for a short time, perhaps a week.
Insofar as the movie goes, it was pretty good. The aeronautical cinematography was very well done and looked very realistic. But it was mostly based around a love story much less about the Czechs and how they became part of the RAF. Thankfully, the love story wasn't too hoaky and didn't seem to overwhelm the war part of the movie a la Pearl Harbor.
Excellent move.
