Andrei Arsenyevich Tarkovsky was a Russian film director and screenwriter. Widely considered one of the greatest and most influential directors in cinema history, Tarkovsky's films explore spiritual and metaphysical themes, and are noted for their slow pacing and long takes, dreamlike visual imagery, and preoccupation with nature and memory.

Solaris is a 1972 Soviet science fiction drama film based on Stanisław Lem's 1961 novel of the same title. The film was co-written and directed by Andrei Tarkovsky, and stars Donatas Banionis and Natalya Bondarchuk. The electronic music score was performed by Eduard Artemyev and features a composition by J.S. Bach as its main theme. The plot centers on a space station orbiting the fictional planet Solaris, where a scientific mission has stalled because the skeleton crew of three scientists have fallen into emotional crises. Psychologist Kris Kelvin (Banionis) travels to the station to evaluate the situation, only to encounter the same mysterious phenomena as the others.
