Doctor Zhivago is a British-American 1965 epic drama–romance film directed by David Lean, starring Omar Sharif and Julie Christie. It is set in Russia between the years prior to World War I and the Russian Civil War of 1917-1922, and is loosely based on the Boris Pasternak novel of the same name, immensely popular in the West, but banned in the Soviet Union at the time. The film takes place mostly against a backdrop of the pre-World War I years, World War I itself, the Russian Revolution of 1917, and the Russian Civil War. A narrative framing device, set in the late 1940s to early 1950s, involves KGB Lieutenant General Yevgraf Andreyevich Zhivago (Alec Guinness) searching for the daughter of his half brother, Doctor Yuri Andreyevich Zhivago (Omar Sharif), and Larissa ("Lara") Antipova (Julie Christie). Yevgraf believes a young woman, Tanya Komarova (Rita Tushingham), may be his niece and tells her the story of her father's life.
