You might know Britt Lower as Helly R. on the hit series “Severance,” but she makes no less of an impression playing a librarian in the new Canadian indie film “Darkest Miriam.” The actor joins Tom Power to tell us how her love of libraries helped her bring her character Miriam to life and what it took to prepare for her “Severance” role — like studying trapped animals and people under interrogation. She also discusses her 2020 short film, “Circus Person,” and how it kind of comes full circle with her current projects. In case you missed it, last week Tom spoke with “Severance” stars Tramell Tillman and Zach Cherry. You can also check out guest host Talia Schlanger’s conversation with “Darkest Miriam” director Naomi Jaye.
