Rachel Williams

Rachel Williams is a Vanity Fair photo editor and fitness devotee who falls into friendship with the glamorous, generous Anna Delvey. She wants in on Anna's world of hotel suites and private jets, and she behaves like a woman flattered to be chosen — eager, a little starstruck, slow to ask hard questions.

Katie Lowes plays Rachel's slide from delight to dread with excruciating precision, letting us watch a smart woman talk herself out of her own alarm bells in real time. The writing uses her as the audience's proxy — we want to believe Anna too — which makes Rachel's mounting unease land as our own.
