Question: For which film about espionage during the Cold War did Bridget O'Connor win the Oscar nomination?
Context: Topaz is a 1969 American espionage thriller film directed by Alfred Hitchcock.  Based on the 1967 Cold War novel "Topaz" by Leon Uris, the film is about a French intelligence agent who becomes entangled in the Cold War politics of the events leading up to the 1962 Cuban Missile Crisis, and later the breakup of an international Soviet spy ring in France.  The story is closely based on the 1962 Sapphire Affair, which involved the head of French Intelligence SDECE in the United States, and spy Philippe Thyraud de Vosjoli—a friend of Leon Uris—who played an important role in "helping the U.S. discover the presence of Russian offensive missiles in Cuba".  The film stars Total Espionage doctrine is a specific approach to intelligence gathering, implicating as many variable sources as possible.  It combines political, economic, financial, military and industrial espionage.  Like other types of espionage, it is subdivided into active and passive espionage.  In its original meaning, it applies to human intelligence (HUMINT).  It characterizes authoritarian and totalitarian regimes.  In the XX century total espionage was practiced by Japan, Germany and the Soviet Russia.  During the Cold War, the Soviet propaganda often accused the United States of total espionage. Max Lang is a film director.  He has been twice nominated Academy Awards in the category of Best Short Animated Film.  In 2011 he received an Oscar nomination for "The Gruffalo", and in 2014 he received an Oscar nomination for "Room on the Broom". A cold war is a state of conflict between nations that does "not" involve direct military action but is pursued primarily through economic and political actions, propaganda, acts of espionage or proxy wars waged by surrogates.  This term is most commonly used to refer to the Soviet-American Cold War.  The surrogates are typically states that are "satellites" of the conflicting nations, i.e., nations allied to them or under their political influence.  Opponents in a cold war will often provide economic or military aid, such as weapons, tactical support or military advisors, to lesser nations involved in conflicts with the opposing country. Tinker Tailor Soldier Spy is a 2011 Cold War espionage film directed by Tomas Alfredson.  The screenplay was written by Bridget O'Connor and Peter Straughan, based on John le Carré's 1974 novel of the same name.  The film, starring Gary Oldman as George Smiley, along with Colin Firth, Tom Hardy, John Hurt, Toby Jones, Mark Strong, Benedict Cumberbatch, and Ciarán Hinds, and featuring David Dencik, is set in London in the early 1970s and follows the hunt for a Soviet double agent at the top of the British secret service. Early histories of a war typically describe the war as it was declared by the states involved.  It is not uncommon for later historians to group together a series of wars over a long period or spread over several theaters as part of a broader conflict or strategic campaign.  The most familiar of these in the present day is probably the Cold War and the War on Terror, which included the Korean War (1950–1953) (Cold War), the Vietnam War (1965–1973) (Cold War), the Persian Gulf War (1990–1991) (Cold War), the War in Afghanistan (2001–2016) (War on Terror), and the Iraq War (2003–2011) (War on Terror) to name these five wars during the Cold War and the War on Terror.  These groupings provide useful context for the wars involved.  Note that some groupings overlap time periods and its possible for more than one war to be going on at the same time. Bridget O'Connor (18 January 1961 – 22 September 2010) was a BAFTA-winning author, playwright and screenwriter.  She may be best known for the play "The Flags", and her posthumously Oscar-nominated adaptation, with her husband, Peter Straughan, of the book "Tinker Tailor Soldier Spy" for the film of the same name.  She died in 2010, aged 49, from cancer.  In 2012, she posthumously won the BAFTA Award for Best Adapted Screenplay along with her husband. Cold War II (also called the New Cold War, Second Cold War and Cold War 2.0) refers to a renewed state of political and military tension between opposing geopolitical power-blocs, with one bloc typically reported as being led by Russia and/or China, and the other led by the United States or NATO.  This is akin to the original Cold War that saw a global confrontation between the Western Bloc led by the United States and the Eastern Bloc led by the Soviet Union, Russia's predecessor state.  American political scientist Robert Legvold posits that the "new Cold War began the moment we went over the cliff, and that happened with the Ukraine crisis."  Others, such as Andrew C. Kuchins in 2016, believe that the term is "unsuited to the present conflict," but the situation is arguably more dangerous than during the original Cold War.  One of the primary features of the "New Cold War", as first defined by Philip N. Howard, is that conflict is experienced primarily over and through broadcast media, social media, and information infrastructure. The Cold War (1947–91) was reflected in culture through music, movies, books, television and other media, as well as sports and social beliefs and behavior.  One major element of the Cold War was the threat of a nuclear war; another was espionage.  Many works use the Cold War as a backdrop, or directly take part in fictional conflict between the United States and the Soviet Union The period 1953–62 saw Cold War themes first enter the mainstream culture as a public preoccupation.  For the historical context in America see United States in the 1950s. The aftermath of World War II was the beginning of an era defined by the decline of the old great powers and the rise of two superpowers: the Soviet Union (USSR) and the United States of America (USA).  Allied during World War II, the USA and the USSR became competitors on the world stage and engaged in the Cold War, so called because it never resulted in overt, declared hot war between the two powers but was instead characterized by espionage, political subversion and proxy wars. Western Europe and Japan were rebuilt through the American Marshall Plan whereas Eastern Europe fell under the Soviet sphere of influence and eventually an "Iron Curtain".  Europe was divided into a US-led Western Bloc and a Soviet-led Eastern Bloc.  Internationally, alliances with the two blocs gradually shifted, with some nations trying to stay out of the Cold War through the Non-Aligned Movement.  The Cold War also saw a nuclear arms race between the two superpowers; part of the reason that the Cold War never became a "hot" war was that the Soviet Union and the United States had nuclear deterrents against each other, leading to a mutually assured destruction standoff.
