In the scene where Vronsky is shown out of Karenin's house after Anna's near death, a Soviet-era lamppost is visible further down the street.
During the movie, title cards inform the viewer that the story arch unfolds in the years 1880 to 1882 - yet at the end of the movie Vronsky leaves to fight in the Russo-Turkish war of 1877- 1878.
Rakhmaninov's music, the Vespers and the Second Symphony, used throughout the film, were not written until at least 30 years after the novel was written and 20 years afterthe film says it is set.
In the pivotal ballroom sequence early in the film, the room is lit with what appears to be entirely electric lighting. The bulbs visible, meant to resemble candle flames, are highly unlikely to have been used in a Russian palace in the early 1880s.
Although the film claims to be set in the 1880s, the book must be set earlier than that because it was published in 1875.
