The Big Little Lies cast has been teasing the possibility of returning for season 3 of the HBO series. In November 2019, Nicole Kidman revealed that she would be open to another season if the writers were also on board. "If there is a third one, all of it will come from the writers, and that’s amazing," she explained to Deadline at the time. "Liane [Moriarty] is deeply talented.
David [E. Kelley] is deeply talented, and the combination of them is extraordinary. So, where they would take it, I have no idea. You have to bow down to the writers, because that really is where it starts. Unless you’re a director/writer, and then you write it. But this show, we’ll see what Liane can muster, and if she has an interest in it."
Reese Witherspoon also opened up about the possibility of reuniting the cast for another season, however, she noted that it would be challenging without director Jean-Marc Vallée after his passing. ²
It is worth noting that the show's creator, David E. Kelley, has not confirmed whether or not there will be a third season. However, he has expressed his admiration for the show's cast and crew, stating that he would be open to the idea of continuing the story if the right opportunity presented itself. ³
As of now, it remains unclear whether or not there will be a third season of Big Little Lies. Fans of the show will have to wait and see if the writers are able to muster up another season. ².
