The Limbo Line is a 1968 British spy thriller film directed by Samuel Gallu and starring Craig Stevens, Kate O'Mara and Eugene Deckers.^[1][2] It is based on the 1963 novel of the same title by Victor Canning. It was made as part of a 1960s boom in spy films in the wake of the success of the James Bond series.

Through a network known as the "Limbo Line", the KGB is kidnapping figures who have recently defected to the West and returning them to the Soviet Union for punishment. A British intelligence agent identifies the ballerina Irina Tovskia as the next victim, and sets out to rescue her in a mission that takes him from London, to Amsterdam and finally to Lübeck on the East German border. He is able to destroy the Limbo Line, but not prevent Irina being taken to Moscow.

It was shot at Pinewood Studios with sets designed by the art director Scott MacGregor.

The Monthly Film Bulletin wrote: "Naively propagandist espionage thriller. Hackneyed dialogue, feeble direction and ludicrous histrionics from most of the cast give the impression of something left over from the worst days of the Cold War."^[3]

The Times called it old-fashioned.^[4]

The Morning Star reviewed it as "disastrously incompetent".^[5]
