Solyaris (Solaris) is a two-part 1968 Soviet television film in black-and-white based on the 1961 novel Solaris by Stanisław Lem. It was the first film adaptation of the novel.
Dr. Kris Kelvin arrives on Solaris Station, a space station orbiting the ocean planet of Solaris. The scientists there have been studying the planet and its ocean for many decades. Shortly before Kelvin's arrival, the crew exposed the ocean to a high-energy gamma-ray bombardment. The ocean's response tests the scientists' minds by confronting them with their most painful thoughts and memories. The ocean does this by materializing physical human simulacra. Kelvin confronts memories of his dead lover and guilt about her suicide. The torments of the other researchers are only suggested but seem even worse than Kelvin’s personal ordeal. The ocean’s intelligence expresses physical phenomena in ways difficult for their limited science to explain, deeply upsetting the scientists. The alien mind of Solaris appears to differ so much from the human mind that communication doesn't seem possible.
In a final experiment, Snaut and Sartorius record Kelvin's brain waves and beam them at Solaris. Unknown to Snaut and Sartorius, while his brain waves are being recorded Kelvin wishes that Kelvin and Snaut's visitors disappear but Harey stays. Kelvin tells the crew that he and Harey are to return to earth. However, Snaut talks to Harey in private and says that she will not be allowed on earth and would not make it anyway as she only exists because of the energy directed at the space station by Solaris. The night before Kelvin and Harey are due to leave Harey tricks Kelvin into taking a sleeping draught and while he is asleep writes effectively a second suicide note to him, then goes to Snaut and Sartorius who have built a machine to cancel out the effects of Solars making the visitors disappear. Harey askes them what it will be like, Snaut say it 'will be like a flash and breath of wind'. Harey is gone, the visitors do not return and the three scientists agree to stay on the station.
