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 blood-testing technology would revolutionize the medical world. She faces up to 20 years in prison. Jarvis says that Holmes is “very much living life” post-conviction, and has been seen out for walks with her partner.
