Allan Segal act as a producer on the investigative current affairs programme World In Action. Over the next five years he produced and directed over twenty films, all over the world, and often in hostile circumstances necessitating the use of hidden cameras and undercover filming. In 1976, Segal and a small film crew risked life imprisonment by posing as tourists and illegally filming in Brezhnev's USSR. Using one of the first ever amateur 8 mm film cameras, they shot "A Calculated Risk", the story of Jewish refusenik Natan Sharansky (who went on to become Deputy Prime Minister of Israel) and his campaign
Bernard Natan from prison, the French government handed him over to the occupying German authorities. Natan was sent to the Auschwitz concentration camp on September 25, 1942, where it is believed he died in 1943. Bernard Natan's importance to the French film industry should not be underestimated. He pioneered the vertical integration of the French film industry, and adopted the "American model" of film-making and distribution. This model provides the underpinning of the French film industry even in the 21st century. Indeed, Pathé survived into the 1980s almost solely on revenues generated by the companies purchased and integration instituted by Bernard Natan.
