Christine Baranski was a successful theatre actor who would never stoop to do television in the old days. But when she got the pilot script for “Cybill,” and had two daughters to put through school, she took the role of Marianne, the tough-talking best friend of Cybill Shepherd’s character. “Who goes to Hollywood at forty-two and becomes an overnight star?” Baranski asks the critic Emily Nussbaum. What made her such a sensation? “No one had seen that woman on American television” before, she notes, of her character, a badass with a Martini and an attitude. “Sex and the City” came later. Playing strong women seems to come naturally to Baranski; since 2009, she’s portrayed the capable, elegant Diane Lockhart, in “The Good Wife” and then “The Good Fight.” She talked with Nussbaum in a live conversation at the 2018 New Yorker Festival. Plus, Amanda Petrusich talks with the musician Kurt Vile, who performs his song “Pretty Pimpin” live.
