背景資料："The film is based on the 2014 novel Red Joan, by author Jennie Rooney, which itself is a fictionalized account of Melita Norwood, a young woman whose work for the KGB wasn't discovered until decades later." “Melita Stedman Norwood was a British communist, civil servant, and KGB intelligence source. She is most famous for supplying the Soviet Union (USSR) with state secrets concerning the development of atomic weapons from her job at the British Non-Ferrous Metals Research Association, where she worked for 40 years。”
她被挖出來之後對自己的辯解是她做這事的目的是為了蘇聯和西方的平衡，為了和平，不想日本被炸的慘劇重演，後來幾十年冷戰中核武器沒有被再使用過證明她是對的。她沒有從前蘇聯收受過報酬和其它好處。
電影中和兩個男人的愛情故事是編的，不是真實的。
我覺得她的行為絕對夠得上traitor, 但客觀上確實起到的製衡的作用。
