Rural England, 1865. Katherine (Florence Pugh) is stifled by her loveless marriage to a bitter man twice her age, and his cold, unforgiving family. When she embarks on a passionate affair with a young worker on her husbandโs estate, a force is unleashed inside her so powerful that she will stop at nothing to get what she wants. Pugh, arguably one of the most exciting screen talents working today, stops by BUILD to discuss "Lady Macbeth" and her starring role in the film.
