How the Cast of Big Little Lies Compares to Their Characters in the Book

Described at one point as "the girliest girl you've ever seen," Madeline is plucky and bubbly, fond of glittery bracelets, and unafraid of making a few enemies when it comes to the pushy PTA moms at the school of her two children. She's best friends with Celeste, and once the shy and awkward Jane moves to town, she ends up being like a cool older sister figure for her. Reese Witherspoon is a pro at playing upbeat, well-meaning characters, and she's been the perfect fit for Madeline.
