As we inaugurate the Walker’s refurbished Cinema, we’re poised at a historical crossroads: we look back over more than 60 years of screenings, dating to the presentation of avant-garde filmmaker Maya Deren’s work in the 1940s, and forward to the kinds of inventive work that carry on the spirit. In fitting style, the first three premieres in this rededicated space offer views of life and desire either through the imperfect mirror of history or the contrived reversal of a palindrome.
