It’s official: HBO has announced that Big Little Lies will return for a second season, and another 7 episodes.

The show, which stars Nicole Kidman and Reese Witherspoon, is based on the eponymous novel by Liane Moriarty. It has been both a critical and commercial success, and has won 8 Emmy awards and received 16 nominations. It has further scored a 92% rating from review aggregator Rotten Tomatoes, based on 94 reviews. What’s more, the show garnered on average well more than a million viewers, with the season finale receiving almost 2 million.

While the network confirmed that Kidman and Witherspoon will definitely be back, the status of the rest of the cast is less certain. All they would say is that “most of the cast is expected to return.” They also indicated that writer David E. Kelley would return and write all of next season’s episodes. He will further continue his role as executive producer of the show, along with Kidman and Witherspoon, and director Andrea Arnold.

As to plot details for the second season, HBO is keeping that under wraps. All they would say is that the show would explore the subjects of lies, friendship, marriage and parenting.

The show was originally marketed as a 7-episode miniseries, but its stars expressed great excitement about continuing for a second season.

Witherspoon said that she hoped that second season would provide an opportunity to go “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.” Kidman added that she was appreciative that she was able to “keep exploring these female characters and make this series with my friends.”
