Released in 1972, Solaris is Andrei Tarkovsky's third feature and his most far-reaching examination of human perceptions and failings. It's often compared to Kubrick's 2001, but although both bring a metaphysical dimension to bear on space exploration, Solaris has a claustrophobic intensity which grips the attention over spans of typically Tarkovskian stasis. Donatas Banionis is sympathetic as the cosmonaut sent to investigate disappearances on the space station orbiting the planet Solaris, only to be confronted by his past in the guise of his dead wife, magnetically portrayed by Natalya Bondarchuk. The ending is either a revelation or a conceit, depending on your viewpoint.
