Opens in UK hospital with Walbrook as war-injured Polish officer agonising over recall of composition:flashback to meeting with N.Y. news correspondent (who quickly supplants US with UK accent) Sally Gray(actress's name) as he ruminates over concerto composition.Further recall to selection by Air pilots' squad to come to US to garner funds for Poland in 1940.Wrenching decision to return East and and as RAF pilot runs out of ammunition and wilfully crashes into German bomber,bringing us back to original scene in hospital room. Conflicts developed very nicely:between hero and other pilots;between hero and close friend over the heroine;between hero and wife about return to UK;and within himself over his future mission:to stay fundraising in US or join RAF.Goes without saying about excellent haunting" Warsaw Concerto" excellently played,very moody amd evocative. When this film came out in '41 the Concerto was criticised as a copy of Grieg's p.concerto in A mi., or Tchaikowski's 2nd in C. All the same it is worth several viewings.
