Chicago Filmmakers begins its five-part retrospective of Yoko Ono's films with Rape (1969) and Erection (1971), collaborations with John Lennon that show the Japanese-born artist broadening her Fluxus philosophy (which questions the role of the camera and the nature of perception) to include a more playful tone and a more explicit political agenda. In Rape a hand held camera tails a young woman through a London cemetery and into her flat, changing from voyeur to stalker (and anticipating Dogma 95). At times Ono reveals that the woman is an actor, deliberately confusing pretense and reality, though the concept fails to sustain the film's 77-minute running time. Erection (20 min.) uses sequences of time-lapse photography to show the construction of a building, with the visual pun of a rising crane backed not only by orgasmic gasps but by clacking wood blocks and droning sounds that evoke a Shinto ceremony.
