In the second of three Deadline roundtables featuring this year’s Emmy nominees for Outstanding Casting, Deadline gathered Mary Vernieu (‘The Last of Us’), Cathy Sandrich Gelfond (‘The Pitt’), Rachel Tenner (‘Severance’), Nina Gold (‘Slow Horses’) and Meredith Tucker (‘The White Lotus’) to talk about discovering new tricks in old talent, and finding young actors who can look and sound like medical residents.
