Manori Ravindran International Editor Frederick Wiseman, a voracious reader, doesn’t watch television. In fact, he’d never really gotten through a whole series until recently, when he watched HBO’s “The Wire.” “I don’t know why, but it was interesting,” he tells Variety drily. Every couple of years, the 92-year-old master documentarian behind such seminal films as “Titicut Follies” and “Juvenile Court” has churned out a sprawling documentary fixated on a microcosm of society or some sort of social issue, but when the pandemic paused those efforts for two and a half years, it’s Wiseman’s literary proclivities that drew him to Sofia Tolstoy’s writing for his new fiction film “Un Couple,” which premiered Friday in Venice’s Competition section.
