David Lean's DOCTOR ZHIVAGO is an exploration of the Russian Revolution as seen from the point of view of the intellectual, introspective title character (Omar Sharif). As the political landscape changes, and the Czarist regime comes to an end, Dr. Zhivago's relationships reflect the political turmoil raging about him. Though he is married, the vagaries of war lead him to begin a love affair with the beautiful Lara (Julie Christie). But he cannot escape the machinations of a band of selfish and cruel characters: General Strelnikov (Tom Courtenay), a Bolshevik General; Komarovsky (Rod Steiger), Lara's former lover; and Yevgraf (Alec Guinness), Zhivago's sinister half-brother. This epic, sweeping romance, told in flashback, captures the lushness of Moscow before the war and the violent social upheaval that followed. The film is based on the Pulitzer Prize-winning novel by Boris Pasternak.
