Elizabeth Wagmeister Senior Correspondent The stars and creatives behind Hulu’s “Tiny Beautiful Things” celebrated the premiere of their upcoming show at an ethereal and intimate event, presented by Hulu, ABC Signature and Variety. “Tiny Beautiful Things” stars Kathryn Hahn as an anonymous and revered advice columnist whose own life is falling apart. Reese Witherspoon and Laura Dern are among the executive producers behind the buzzy show, which begins streaming on April 7 on Hulu. Adapted for television by Liz Tigelaar, “Tiny Beautiful Things” is based on Cheryl Strayed’s New York Times bestseller of the same name, which is comprised of a collection of essays from Strayed’s “Dear Sugar” advice column, which she wrote anonymously more than a decade ago.
