On the hit series “The Bear,” Liza Colón-Zayas plays a middle-aged line cook named Tina who’s challenged by her mentors to learn new skills as a sous-chef. In some ways, her character’s story mirrors her own journey as an actor. With Season 4 of “The Bear” out now, we revisit Liza’s conversation with Tom Power about the scarcity and struggle she had to overcome on her path to success, her experience in a strict religious group that forced her to surrender all her wages to them, and how her setbacks continue to shape her as an artist. If you like this conversation, you should also check out Tom’s interview with Matty Matheson.
