The movie lines are not Lenin's works. "Thinking about the past in the name of revolution, forgetting the past means betrayal." This sentence is almost a household name, and many people think it is a famous saying of Lenin. However, it is actually a line of Lenin in China's children's play The Name of Revolution. In the Name of Revolution was widely spread in 1950s and made into a film in 1960s. With the popularity of children's dramas and movies, this sentence has been recited by more and more people and mistaken for Lenin's words.
