The makers of a pioneer documentary film on North Korea and its World Cup team of 1966 plan to show it in both Koreas ahead of this summer's finals - and they deny allegations the players were purged on their return to the Stalinist country. A five-man British film crew, led by producer and director Daniel Gordon and associate producer Nicholas Bonner, have just completed an 80-minute film, The Games of Their Lives, about the seven surviving members of the North Korean team who defeated Italy in the finals in England, arguably the biggest upset in the history of the World Cup. The film cost GBP300,000 to make. It was the first time the North Koreans had co-operated with a Western documentary film crew, after four years of negotiations. In an interview this week in Beijing, where he runs Koryo Tours, a travel company specialising in tours to North Korea, Bonner said that, while BBC Digital had acquired the broadcast rights for Britain, they planned to show it in both Koreas, Japan and around the world ahead of the World Cup, which begins on May 31. Minnows North Korea were beaten 3-0 in their first group game against the Soviet Union. They then drew 1-1 with Chile and needed a win against Italy, then one of the strongest teams in the world, to avoid elimination. Amazingly, they beat them 1-0, the winning goal being scored in the 41st minute by Pak Do-ik, who became a national hero. The Italians took the next flight home and were pelted with tomatoes on their arrival. In the quarter-finals, the North Koreans astonishingly led 3-0 after 24 minutes against Portugal, then - as now - one of the world's leading teams, before the legendary Eusebio scored four times to lead Portugal to a 5-3 victory. Since then, North Korea have not qualified for the World Cup finals, in part because of political disputes with South Korea, which has become one of the strongest Asian soccer nations and is co-hosting the finals this year with Japan. A book, Aquariums of Pyongyang, published last November and written by Frenchman Pierre Rigoulot, which was based on interviews with a North Korean who defected to the South, said the team had been purged on their return home because of wild parties and womanising in Middlesborough, where they were based during the tournament. 'We reject these allegations,' Bonner said. 'They were national heroes when they returned and they are now. Middlesborough is a small place and everyone would have known of their partying. Those who were waitresses at the time told us they flirted but that was all. All they drank was mineral water. People there still remember this with great fondness. 'On their return, each was given an apartment and a holiday. One of them, scorer Pak, later received a Mercedes because he became a famous coach. When police stop the car, they always let him through when they find out who he is.' The film-makers had access to North Korean print and broadcast archives, including a two-hour official film made of the team and their experiences in England. 'We were given very good access. There was nothing we were not allowed to ask,' Bonner said.
