this interruption and destroyed most of the film. Film career outside the Soviet Union During the summer of 1979, Tarkovsky traveled to Italy, where he shot the documentary Voyage in Time together with his long-time friend Tonino Guerra. Tarkovsky returned to Italy in 1980 for an extended trip, during which he and Guerra completed the script for the film Nostalghia. During this period, he took Polaroid photographs depicting his personal life. Tarkovsky returned to Italy in 1982 to start shooting Nostalghia, but Mosfilm then withdrew from the project, so he sought and received financial backing from the Italian RAI. Tarkovsky completed the film in 1983, and it was presented at the Cannes Film Festival where it won the FIPRESCI prize and the Prize of the Ecumenical Jury.

On 28 August 1985, Tarkovsky was processed as a Soviet Defector at a refugee camp in Latina, Italy, registered with the serial number 13225/379, and officially welcomed to the West. Tarkovsky spent most of 1984 preparing the film The Sacrifice. It was finally shot in 1985 in Sweden, with many of the crew being alumni from Ingmar Bergman's films, including cinematographer Sven Nykvist. Tarkovsky's vision of his film was greatly influenced by Bergman's style. While The Sacrifice is about an apocalypse and impending death, faith, and possible redemption, in the making-of documentary Directed by Andrei Tarkovsky, in a particularly poignant scene, writer/director Michal Leszczylowski follows Tarkovsky on a walk as he expresses his sentiments on death—he claims himself to be immortal and has no fear of dying.
