Triple Cross

Triple Cross is a 1966 British-French spy film directed by Terence Young. It tells the story of Eddie Chapman, a safecracker turned wartime agent whom the Germans believed to be their top spy in Britain, while he was in fact an MI5 double agent operating under the codename "Zigzag". The screenplay draws on the 1953 autobiography Chapman wrote together with Frank Owen. Christopher Plummer stars in the lead role, supported by Romy Schneider, Yul Brynner, Gert Fröbe, Trevor Howard and Claudine Auger. The title refers to the Morse signature XXX that Chapman used to signal to the Germans that he was transmitting freely; a second meaning emerges in the closing scene, when Chapman, seated at a bar and asked who he truly worked for, raises his glass to his own reflection in the mirror. Released in France in December 1966 and elsewhere in Europe and the United States in 1967, the film met with mixed reviews.
