What they’re saying

“It felt like I was catching up with old friends. I really hope readers experience that same sense of a reunion. Of course I've changed since I wrote Big Little Lies, and the world has changed, so it was fascinating to think about how these characters might have changed too especially as they deal with the challenges of raising teens.”

— Liane Moriarty, Author

“Right from the beginning, because of the show, there was talk about writing a sequel, but I was never interested right away because you put your characters through so much and it just didn't make sense to me to write something that followed on directly. A time jump always made sense to me.”

— Liane Moriarty, Author

“There would be nothing more fun for all of us.”

— Laura Dern

“It's one of those shows where the cast, we're just all so close and we text each other all the time and we're just always hanging out with each other, so it was a really special show.”

— Reese Witherspoon
