Here’s a movie you don’t see often on television, much less in prime time: It’s F.W. Murnau’s silent drama, a movie about love and betrayal and lust and longing and reconciliation. George O’Brien and Janet Gaynor star as a married couple from the country, and Margaret Livingston plays the Woman from the City who tempts him not only to embrace both her and the big city, but tries to persuade him to murder his wife. And in one bold sequence, accomplished within the camera via a tricky multiple exposure, the temptress haunts him literally, by embracing him in spectral form. In a movie made in 1927.
