Doctor Zhivago is a British 1965 epic drama–romance film directed by David Lean, starring Omar Sharif and Julie Christie. It is set in Russia during World War I and the Revolution, and is loosely based on the Boris Pasternak novel of the same name, immensely popular in the west, but banned in Russia at the time. For this reason, the film could not be made there, but mostly in Spain.
The critics were generally disappointed, complaining of its length at over three hours, and claiming that it trivialised history, but acknowledging the intensity of the romantic drama and the treatment of human themes. Over time, however, the film's reputation has improved greatly. It is now regarded as among David Lean's finest films, as well as one of the best films of the epic genre.
