Sarah Polley’s Oscar-winning film “Women Talking” is a powerful story about three generations of women who sit down to debate their future after realizing they and their daughters have been regularly drugged and sexually assaulted by the men in their colony. Sarah tells Tom about her approach to adapting works of fiction, what it was like stepping back from the film industry after a concussion, and how she used her experience as a child actor to create the best environment possible for the children on the set of “Women Talking.” Plus, Celeigh Cardinal is a Juno-winning singer-songwriter who’s been praised for her soulful torch songs tinged with blues and R&B. She tells guest host Talia Schlanger the story behind her new song “Over Before It Began.”
