Doctor Zhivago (1965)

Continuity mistake: The city railroad scenes were filmed in Spain, and many of the forest railroad scenes were filmed in Finland; in both of those countries, most of the railroad track is broad gauge (the rails are more than 5 feet apart). The plains and mountains railroad scenes were largely shot in Canada, where the rails are "standard gauge": 4' 8 & 1/2" apart. The rails can be seen to jump between far apart and closer together more than once as the movie progresses.

Factual error: This movie is set in a part of the world that is well known for its harsh cold weather and frigid temperatures. Yet despite countless scenes of people outdoors in what is supposed to be the bitter cold of winter, you never see the vapor from anyone's breath.

Audio problem: During the "peaceful protest" scene, in a close-up of the crowd the mouth movements don't match the soundtrack.

Trivia: Geraldine Chaplin, the actress who plays Dr. Zhivago's wife, is the daughter of the silent film actor, Charlie Chaplin. Her maternal grandfather was famed playwright Eugene O'Neill.

Gen. Yevgraf Zhivago: A nameless number on a list that was lost, or mislaid. That was common in those days.

Pasha: They rode them down, Lara. Women and children, begging for bread. There will be no more 'peaceful' demonstrations.

Zhivago: You lay life on a table and cut out all the tumors of injustice. Marvelous.
