Argo From Wikipedia
Upon its wide release in October 2012, the film was criticized for its claim that the New Zealand and British diplomats had turned away the American refugees in Tehran. Diplomats from New Zealand had proved quite helpful; one drove the Americans to the airport[41], and organised a place for them to hide if they had to change places.[42] The British hosted the Americans initially, but the location was not safe and all considered the Canadian ambassador's residence to be the better location. British diplomats also assisted other Americans beyond the six.[43] Bob Anders, the U.S. consular agent played in the film by Tate Donovan, said, "They put their lives on the line for us. We were all at risk. I hope no one in Britain will be offended by what's said in the film. The British were good to us and we're forever grateful."[44]
Sir John Graham, the then-British ambassador to Iran, said, "My immediate reaction on hearing about this was one of outrage. I have since simmered down, but am still very distressed that the film-makers should have got it so wrong. My concern is that the inaccurate account should not enter the mythology of the events in Tehran in November 1979." The then-British chargé d'affaires in Tehran said that, had the Americans been discovered in the British embassy, "I can assure you we'd all have been for the high jump [i.e., in trouble]."[44] Martin Williams, secretary to Sir John Graham in Iran at the time, was the one who found the Americans and sheltered them in his own house at first. The sequence in the film when a housekeeper confronts a truckload of Iranian revolutionary at the Canadian ambassadors home bears a striking resemblance to Mr Williams' own story. He has told how a brave guard, Iskander Khan, confronted heavily-armed revolutionary guards and convinced them that no-one was in when they tried to search Williams' house during a blackout. Mr Williams said "They went away. We and the Americans had a very lucky escape." The fugitives later moved to the home of the Canadian ambassador and his No2.[45]
Affleck is quoted as saying to The Sunday Telegraph: "I struggled with this long and hard, because it casts Britain and New Zealand in a way that is not totally fair. But I was setting up a situation where you needed to get a sense that these six people had nowhere else to go. It does not mean to diminish anyone."[44]
