Polish film Poklosie or Aftermath is a dramatisation of the massacre of more than 340 Polish Jews at Jedwabne in 1941.
It has caused shockwaves and soul searching throughout the country.
It tells the story of a Polish man who returns to his home village and finds himself reluctantly drawn into uncovering what happened there during the Nazi occupation.
He discovers that, at the instigation of the Nazis, local people – including his own father – had herded Jewish villagers into a building, burned them to death, and then taken over their houses.
Opponents of the film argue it discredits Poland by creating the impression that such events were the norm in wartime. Some have accused the actors of slandering their country. One, Maciej Stuhr, has even received death threats.
