Doctor Zhivago is a 1965 British-American epic drama–romance film directed by David Lean and 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 based on the Boris Pasternak novel of the same name. While immensely popular in the West, the book was banned in the Soviet Union for decades. For this reason, the film could not be made in the Soviet Union and was instead filmed mostly in Spain.
