Vivian Ostrovsky is a casual collagist with an affectionate eye for leisure activity. Copacabana Beach (1983) and Public Domain (1996) are Super-8 sketchbooks of people strolling, jogging, and walking their dogs, blown up to 16-millimeter and counterpointed by scores that sample radio tunes and overheard conversations. More rewarding is Nikita Kino (2002), in which she expands her materials to include personal narration, home movies, and copious clips from Soviet cinema and newsreels. In 1960 her father in Brazil learned that his long-lost brother and sister were living in Moscow; jerky Super-8 footage of his annual visits is comically intercut with official versions of life in the USSR, revealing the Soviets’ paranoia and state anti-Semitism and Ostrovsky’s endless fascination with elderly women doing exercises. 63 min.
