Partner.

This rather ludicrous exchange takes place at the end of David Lean's adaptation of Boris Pasternak's epic novel DR. ZHIVAGO:

Gen. Yevgraf Zhivago: Tonya, can you play the balalaika?

Tonya's Boyfriend: Can she play? She's an artist!

This dialogue, as well as the scene within the framing device of Yuri Zhivago's brother Yevgraf finding Yuri's love child with Lara and telling her about her "past," appears nowhere in the novel. Instead, in an epilogue in the novel, two of the many characters, after the end of the Great Patriotic War (World War II), talk about how one had met this love child at the front. Their ruminations illustrate the great dislocations caused by the Revolution, Stalin's Terror, and the War. Nowhere does something as silly and trivial as the question "Can you play the balalaika?" appear in the novel.

Movies that use great events as backdrops to personal stories tend to trivialize the great events and make the intimate lives of their characters rather absurd and trivial (ironically, the very charge Strelnikov makes to Zhivago, in reference to his poetry, in Lean's movie). Great events such as revolutions wash over everyone and have to be handled with the greatest care to avoid this fundamental absurdity of the events being greater than the individuals.

Before "The Dreamers," Bertolucci already made his film that ruminates on the events of '68 and its aftermath in the year itself:

"Partner" ("Il Sosia"), based on Dostoyevsky's "The Double." It is very interesting, and very honest, look at the spirit of the times and I highly recommend it.
