1900 (Italian: Novecento, "Twentieth Century") is a 1976 epic historical drama film directed by Bernardo Bertolucci, and featuring an international ensemble cast including Robert De Niro, Gérard Depardieu, Dominique Sanda, Francesca Bertini, Laura Betti, Stefania Casini, Ellen Schwiers, Sterling Hayden, Alida Valli, Romolo Valli, Stefania Sandrelli, Donald Sutherland, and Burt Lancaster.

Set in Bertolucci's ancestral region of Emilia, the film chronicles the lives and friendship of two men – the landowning Alfredo Berlinghieri (De Niro) and the peasant Olmo Dalcò (Depardieu) – as they witness and participate in the political conflicts between fascism and communism that took place in Italy in the first half of the 20th century.

Its great length led to its being presented in two parts when originally released in many countries, including Italy, East and West Germany, Denmark, Belgium, Norway, Sweden, Colombia, Pakistan and Japan.

[4] 1900 has become widely regarded as a cult classic, and has received several special edition home video releases from a variety of distributors.

On an estate in Emilia-Romagna, the peasants seek to join the partisans and place the owner, Alfredo Berlinghieri, under arrest.

In 1917, Olmo enlists in the Royal Italian Army for World War I, while Alfredo learns to run the family's plantation.

Giovanni, Alfredo's father and the new padrone, hires Attila Mellanchini, a fascist foreman who treats estate employees cruelly.

Accused of letting workers suffer, Alfredo is sentenced to death but saved when Olmo declares the padrone dead, symbolizing the overthrow of the social system.

The film concludes with a scene of the elderly Alfredo and Olmo playfully tackling each other, then jumping forward to them walking along a railway track.
