This austere experimental documentary from Switzerland will reward only patient viewers. Director Thomas Imbach, stationing his camera in a window that overlooks a drab area of Zurich, records parked cars, a towering smokestack, passing planes and trains, and the changing seasons. On the soundtrack snippets of Bob Dylan songs covered by other artists alternate with voice mails from the filmmaker's friends, lovers, relatives, and business colleagues. Occasionally an image seems to comment on a phone message (a rebuke from an ignored girlfriend is followed by shots of a leggy female neighbor parading in and out of the frame). As the callers age, you realize you're witnessing a time capsule, an oblique portrait of the artist as an absent man. In Swiss German dialect with subtitles.
