Following the gorgeous, seemingly liberated Adriana (Divorce Italian Style’s Stefania Sandrelli) as she chases her dreams in the Rome of La dolce vita, I Knew Her Well is at once a delightful immersion in the popular music and style of Italy in the sixties and a biting critique of its sexual politics and the culture of celebrity. Over a series of intimate episodes, just about every one featuring a different man, a new hairstyle, and an outfit to match, the unsung Italian master Antonio Pietrangeli, working from a script he cowrote with Ettore Scola, composes a deft, seriocomic character study that never strays from its complicated central figure. I Knew Her Well is a thrilling rediscovery, by turns funny, tragic, and altogether jaw-dropping.
