Martin Freeman is set to star in a BBC Two feature-length drama called The Eichmann Show.
The drama is about the televising of the 1961 trial of Adolf Eichmann, one of the main architects of the Nazi "final solution" to exterminate the Jews of Europe.
The Sherlock star will play TV producer Milton Fruchtman who worked on the televising of the trial.
Anthony LaPaglia is also set to appear in the drama as director Leo Hurwitz.
The 90-minute film will be the centrepiece of the BBC's season to mark the 70th anniversary of the liberation of Auschwitz-Birkenau, the largest Nazi concentration camp during World War II.
Danny Cohen, the BBC's Director of Television, said: "The liberation of the camps is a very significant anniversary which the BBC will mark with a range of thought-provoking programmes."
The Eichmann trial was televised in 37 countries and marked the first time most people heard about the full horror of the Nazi death camps.
