Yuli Raizman - Kommunist (Коммунист) AKA The Communist (1958)

Synopsis: In 1919 workers arrive by train in the middle of the Taiga in order to construct a town. They fell trees and unload bricks from the train for that purpose. The newly arrived hero Vasilij is made chief of the depot, meets hostility and has to put down corruption. (In one scene he searches the the foreman and finds a few nails hidden in his pocket.) Vasilij shares a cabin with other workers and a couple who sleep in a corner of the room behind a curtain. He falls in love with the woman and secretly meets her and makes her pregnant. Counter-revolutionaries (so I guess) try to prevent the building of the town, but Vasilij persists in felling more trees and by his example gets the other workers to join him. His relationship with the woman is discovered and the woman is beaten, bound and imprisoned. Vasilij rescues her, she flees to a beautiful modern clinic and gives birth. The counter-revolutionairies set the town on fire and kill Vasilij who meats a very heroic death in the mud. At his funeral the village kommissar holds a speech. The woman's husband tries to win her back, but she refuses.

Based on a novel by Stanislaw Lem, Solaris centers on widowed psychologist Kris Kelvin (Donata Banionis), who is sent to a space station orbiting a water-dominated planet called Solaris to investigate the mysterious death of a doctor, as well as the mental problems plaguing the dwindling number of cosmonauts on the station.

Finding the remaining crew to be behaving oddly and aloof, Kelvin is more than surprised when he meets his seven-years-dead wife Khari (Natalya Bondarchuk) on the station. It quickly becomes apparent that Solaris possesses something that brings out repressed memories and obsessions within the cosmonauts on the space station, leaving Kelvin to question his perception of reality.

Andrei Tarkovsky - Ivanovo detstvo AKA Ivan's Childhood [+Extras] (1962)

Plot Synopsis
This debut feature-length wartime drama by noted Russian director Andrei Tarkovsky was a remarkable introduction to a remarkable career. The poetic touch of Tarkovsky's hand and his measured pace is already evident as the tale of the young, twelve-year-old Ivan (Nikolai Burlyayev) evolves. Ivan is orphaned after his village is wiped out by an invading Nazi army and as a consequence, he ends up in a prison camp. The inventive lad escapes and is adopted by Captain Kholin (Valentin Zubkov), whose intention is to send the boy away to school. But Ivan is determined to help the Russian army and so he starts spying on the German forces. Because of his tender years he manages to pass freely back and forth behind enemy lines -- at least for awhile. This exemplary film won the top prize, the Golden Lion award at the 1962 Venice Film Festival and also won the Grand Prize at the 1962 San Francisco Film Festival. - Eleanor Mannikka, All Movie Guide
