Rebecca Jarvis, the journalist whose podcast inspired the new Hulu series “The Dropout,” says Amanda Seyfried nailed the role of Theranos founder Elizabeth Holmes — and not just with her signature, deep voice. Two months ago, Holmes was convicted of defrauding investors with wild claims that her company’s bloodtesting technology would revolutionize the medical world. She faces up to 20 years in prison. Jarvis says that Holmes is “very much living life” postconviction, and has been seen out for walks with her partner.
