Halfway through their Actors on Actors conversation, Brie Larson and Andrew Scott discover something they have in common: Neither of them is a trained actor. Larson brings up the subject almost hesitantly, to explain why she has difficulty talking about her craft. “I didn’t go to school for it,” she says. “No! I didn’t either!” Scott replies. Excitedly, Larson says: “I knew I liked you!” Despite any self-professed deficiencies about discussing acting, Larson and Scott insightfully talk about how they each got their start at a young age, and then dive into their current television projects: his remake of “Ripley” on Netflix and her Apple TV+ limited series “Lessons in Chemistry,” which Larson also developed as an executive producer. Both shows originate from books — Patricia Highsmith’s classic thriller and Bonnie Garmus’ 2022 bestseller, respectively — and though their characters are very different (Tom Ripley is a grifter turned murderer; Elizabeth Zott is a thwarted physicist), both stand apart from society, looking in from the outside.
