THOR (12A) has all the hallmarks of a movie made not for its own sake but for the purpose of establishing a franchise.

Based on a true incident from the Cold War era when a top KGB agent – codenamed Farewell – leaked vital information about the Soviet Union’s vast spy network to the French who passed it on to the USA resulting in far-reaching consequences.

A heart-lifting story of humanity amid the carnage of bloody war, and based on a remarkable true incident from World War One.
