Ricki Lake’s career took off when she was 19 and starred as Tracy Turnblad in John waters’ cult film Hairspray. Lake played a high school student whose hair was so big that the kid who sat in back of her complained that he couldn’t see the teacher. Lake went on to do a talk show that lasted for 11 seasons. Now she makes documentaries about women’s health. Her latest one is called The Business of Birth Control. We talk about the art of reinventing yourself and all the phases of Ricki Lake’s life in the new episode of “Now What?”
