Three inmates at the Cherry Trees Sanatorium believe themselves to be world famous physicists: Albert Einstein, Isaac Newton, and Johann Mobius. But are they indeed insane? And what are their actual identities: madmen, murderers or scientists? Friedrich Dürrenmatt's 1962 comedy (translated by James Kirkup) is a provocative examination of the impact of nuclear science on global power and the moral tolls of sanity. Kevin O'Rourke directs.
