Trivia, insights & behind the scenes
Real Jerzy Szajnowicz-Iwanov was a Greek-Polish athlete turned SOE operative; the film soft-pedals his British intelligence ties for obvious 1972 Poland reasons.
This was a Polish-Bulgarian co-production during the communist era, which explains why the Greek resistance looks suspiciously like Eastern European partisans in better tans.
