 All of the principal characters of the film play a role in the opera, though the audience watching the opera is unaware that some of the events portrayed are more than drama.The 1990 biopic "Korczak", about the last days of a Jewish children's orphanage in Nazi occupied Poland, features an amateur production of Rabindranath Tagore's "The Post Office", which was selected by the orphanage's visionary leader as a way of preparing his charges for their own impending death.That same production is also featured in the stage play "Korczak's Children," also inspired by the same historical events.
