Ever since her incredible performance in "I've Heard The Mermaids Singing" 35 years ago, Sheila McCarthy has been one of Canada's most hardworking and reliable actors in theater, television, and film on both sides of the border. In her latest project, she joins a "murderers' row" lineup of actresses like Judith Ivey, Claire Foy, Jessie Buckley, Frances McDormand, and Rooney Mara in Sarah Polley's powerful new film "Women Talking." On this episode, she talks about how the production was both daunting and exhilarating, why it felt like the "acting olympics," what having this "extraordinarily ordinary" powerhouse director at the helm brought out of her, plus wonderful stories about a debt owed to Liza Minnelli and a letter that changed Bruce Willis.
