Jenifer Lewis is known as the “Mother of Black Hollywood” for good reason; her screen progeny have included Whitney Houston, Angela Bassett, and Tupac Shakur. In her latest turn, she’s playing the alpha boss of a home-shopping network on the Showtime series “I Love That For You.” It’s no surprise that Lewis keeps getting cast as formidable ladies—the roles come naturally to her, as you’ll hear in her conversation with the New Yorker contributor Michael Schulman. Lewis’s new memoir is called “Walking in My Joy: In These Streets.”
