The first season was originally thought to be a one-off, as it covered the entirety of author Liane Moriarty's book. However, David E. Kelley is confirmed to return and has already penned all seven of the scripts for season two, which is partially based on a story by Moriarty, who will also produce.

HBO programming president Casey Bloys said, "I’m excited to announce the return of Big Little Lies. David Kelley wrote beautiful scripts and Reese and Nicole were, once again, a force to be reckoned with, reuniting the cast and recruiting the talented Andrea Arnold to direct. We look forward to working with this amazing group of artists."

Season two is set to explore the "malignancy of lies, the durability of friendships, the fragility of marriage and, of course, the vicious ferocity of sound parenting. Relationships will fray, loyalties will erode … the potential for emotional and bodily injury shall loom."

Witherspoon, who originally optioned the rights to the book with Kidman said, "I'm thrilled to be bringing back this talented team of artists. It gives us the opportunity to delve deeper into the lives of these intriguing and intricate Monterey families and bring more of their stories back to the audience who embraced and championed them. I’m beyond excited to be working with talented and acclaimed director Andrea Arnold who will be at the helm. Andrea’s unique storytelling style will be a welcome addition to the filmmaking team."

While Kidman said, "This is inspired by the overwhelming response by audiences around the world, conceived once again by Liane Moriarty, realized by David Kelley and now in the hands of visionary filmmaker Andrea Arnold. What a journey this has been. I’m so grateful to have this opportunity to keep exploring these female characters and make this series with my friends."

There has been nothing hinted at as of yet regarding when we may get to see this second season, but at this stage, it will likely be the end of 2018.
