"Dr. Zhivago," directed by David Lean and based on the novel by Boris Pasternak, is a work of fiction, though it reflects the historical context of early 20th-century Russia, particularly the Russian Revolution and its aftermath. While the characters and plot are not directly based on real individuals or events, Pasternak's experiences and observations during that turbulent period influenced the narrative. The novel explores themes of love, loss, and the impact of political upheaval on personal lives, making it resonate with the realities of the time.

"Dr. Zhivago," directed by David Lean and based on Boris Pasternak's novel, was banned in the Soviet Union due to its critical portrayal of the Russian Revolution and the subsequent Soviet regime. The film's themes of individual struggle against oppressive forces, as well as its focus on personal love and loss amidst political turmoil, conflicted with the state's ideology. Additionally, Pasternak's novel was initially published in Italy and deemed subversive, leading to the film's censorship in the USSR once released in 1965.
