1966 British-French film by Terence Young
Triple Cross (French: La Fantastique Histoire Vraie d'Eddie Chapman, lit. 'The Fantastic True Story of Eddie Chapman') is a 1966 biographical war spy film directed by Terence Young and starring Christopher Plummer, Romy Schneider, Yul Brynner, Gert Fröbe, Trevor Howard and Claudine Auger. It is based on story of Eddie Chapman, believed by the Germans to be their top spy in Great Britain, although he was an MI5 double agent known as "Zigzag". The screenplay is based on Chapman's 1953 autobiography, co-authored with Frank Owen.
The title of the film comes from Chapman's signature to show the Germans that he was transmitting freely: a Morse code XXX (X = â–„â–„â–„ â–„ â–„ â–„â–„â–„). Another meaning of the title Triple Cross becomes clear in the final scene of the film. Chapman, sitting at a bar, is asked who he was really working for. In reply, he raises his glass in salute to his reflection in the mirror.
The film was a British and French co-production, filmed in Eastman Color, print by Technicolor. It was released in France in December 1966 and elsewhere in Europe and the United States in 1967. It received mixed reviews.
