Based off of the John le Carré novel of the same name, "Tinker Tailor Soldier Spy" revolves around British Intelligence, often known simply as "the Circus." Gary Oldman plays the part of George Smiley, an officer within the Circus who was forced to retire after a botched mission results in the seeming assassination of an agent. Smiley and his former boss, Control, have suspected that one of the senior intelligence officers within the Circus is, in fact, a mole embedded by the Soviets. Sometime later, Smiley is asked by undersecretary Oliver Lacon (Simon McBurney) to return and help spearhead an investigation. In order to speak in secrecy about the alleged mole within the intelligence agency, Control had originally given the suspected officers codenames from an old English children's rhyme called "Tinker, Tailor." The film is a rousing game of "whodunit" and weaves in red herrings along the way.
George Smiley sets out to uncover the truth. Along the way, he also learns other unsavory truths about those in his own life and within the agency. "Tinker, Tailor, Soldier ,Spy" is a brilliant adaptation of the source material and boasts a highly talented cast including Gary Oldman, Colin Firth, Tom Hardy, Mark Strong, Ciarán Hinds, Benedict Cumberbatch, John Hurt, and many more.
