Strathairn visits Poland to perform his solo stage play "Remember This: The Lesson of Jan Karski". The theatrical piece is based on the life of Jan Karski who was a courier for the Polish Underground during World War II. In 1942, Karski volunteered to infiltrate the Warsaw Ghetto and a Nazi camp before travelling to London to report to the Allied Nations on the conditions of occupied Poland and, specifically, the Holocaust. His reports were one of the first documentations of Holocaust atrocities but at that time they were largely treated with scepticism or ignored. Pictured: director Derek Goldman.
