In the sprawling, high-definition glare of modern Los Angeles, where fame is often measured by the volume of one’s voice or the frequency of their curated digital presence, a recent moment of quiet profoundness occurred on a sun-dappled sidewalk. Linda Hunt, the Oscar-winning luminary whose career has been defined by the gravity of her silence rather than the noise of her acclaim, was seen in a rare public appearance. At 80 years old, Hunt moved with a serene, unhurried assurance that stopped onlookers in their tracks. Accompanied by her wife of many decades, Karen Kline, and an assistant, the legendary actress embodied a state of existence that is increasingly rare in the entertainment industry: pure, unadorned presence.
