Mimino(1977)

This Georgian comedy Mimino(means Falcon) is a nice watch, it is funny and warm. I would recommend it but I must say that it is not completely in Russian, some parts are in Georgian.

Little Moscow(2008)

Great! movie,I liked this one very much. Highly recommended!!

Mała Moskwa is set in the 1960s in the southwestern Polish city of Legnica, where Krzystek(the director of this movie) was born in 1953. Legnica was the headquarters of the Soviet forces stationed in Poland from 1945 until 1990 and much of the city was a Soviet enclave closed to outsiders, including Polish citizens, during this time. Yuri (Dmitry Ulyanov) is a young Russian pilot and failed astronaut posted to Legnica with his even younger wife Vera (Svetlana khodchenkova, judged best leading actress for her performance). Vera learns Polish and becomes fascinated with Polish music and poetry. She meets Polish officer and musician Michał (Lesław Żurek) at a Polish-Soviet “friendship song contest” which she wins. The story inexorably leads to tragedy as Vera desperately tries to stop herself from falling in love with Michał, equally desperately tries to hide her infatuation when this fails, and finally kills herself. The grave of the Russian woman on whose life Mała Moskwa is based still attracts visitors.http://www.foriegnmoviesddl.com/2009/04/maa-moskwa-little-moscow-2008-waldemar.html

The Ascent (1977) - Voskhozhdeniye

Yet another famous Soviet Movie, The Ascent (Voskhozhdeniye ) is listed in the 20 Must See Films list of Russian Life magazine (20 Must See Russian Films of course :) )

Two soviet partisans separate from their group to go yo the nearest village and find some food but they are captured by the Germans, you can feel the cold and freezing snow ..one more time remember how wild and cruel is the war, especially the WWII.

BUT I must say that the movie is only average,it can be considered slow on today's basis.More info on this black and white movie is here.

Shadows of Forgotten Ancestors (1964)

Shadows of Forgotten Ancestors(Tini zabutykh predkiv) is another famous Soviet movie, but I personally did not enjoy it very much, maybe I did not get the implications or symbols. The movie has 8.1/10 on IMDB.
The only good thing about this movie is you can see the daily village life, clothes, music in the Carpathian region.
