One of the most talked about Czech films of the year, Dark Blue World, by Oscar-winning director Jan Sverak, tells the story of Czech pilots who served in the RAF during World War II, when Czechoslovakia was occupied by the Nazis. Well over two thousand Czech airmen joined the RAF to fight the Germans, and many took part in the Battle of Britain. In this week's Talking Point looks at the story of the Czech pilots who inspired not only a successful film, but a generation of Czechs that has gradually learned of the pilots' sacrifices and bravery.
