HBO; Showtime; Lionsgate; Natalie Ammari/BIShailene Woodley is always chasing butterflies.Not literal ones, of course. The metaphorical kind — the internal fluttering when she reads a script and immediately resonates with a character or finds out who's attached to the project and knows with certainty that she needs to be part of it."Everything is butterfly-based for me," Woodley tells Business Insider.This intuition has been Woodley's north star throughout her career, guiding her to roles as a teen mom in "The Secret Life of the American Teenager," the brave protagonist in the "Divergent" film franchise, and a single mother carrying trauma in "Big Little Lies," which earned the actor her first Emmy nomination in 2017.It also led her to her most recent role as a grieving writer named Gia in Starz's new series "Three Women," based on Lisa Taddeo's best-selling book of the same name.Her character, a fictionalized version of Taddeo, travels across the country and convinces three women to share their stories as part of an assignment to write about sex in America.The series is a raw and honest look at female pleasure, something that Woodley delights in talking about, even if it still makes some people uncomfortable."One of my favorite subjects is desire and pleasure and sex," Woodley says.
