Katy Polish pronunciationkat is a 2007 Polish film about the 1940 Katyn massacre, directed by Academy Honorary Award winner Andrzej Wajda. It is based on the book Post Mortem The Story of Katyn by Andrzej Mularczyk. It was nominated for Best Foreign Language Film for the 80th Academy Awards.
During the German occupation of Poland, the Germans used the massacre for propaganda purposes against the Soviets. However, after the war, when Poland fell under Soviet influence, the truth about the event was suppressed by the Soviet authorities, who maintained an official line throughout the Eastern Bloc that the massacre was committed by the Germans. With the fall of communism in Poland in 1989, the first noncommunist Polish government immediately acknowledged that the crime was committed by the Soviets. In 1990, Mikhail Gorbachev acknowledged Soviet responsibility for the Katyn massacre for the first time. In 1991, Boris Yeltsin made public the documents which had authorised the massacre.There are now some cemeteries of Polish officers in the vicinity of the massacres, but many facts of the event remain undisclosed to this day and many graves of the Polish POWs east of the Bug River are either still unmarked or in a state of disrepair. ........
