Big Little Lies author Liane Moriarty has heard the requests for more of the HBO limited series.

Following the breakout first run of the Reese Witherspoon and Nicole Kidman starrer, the Australian author is hard at work planning a potential second season of the critical favorite.

"I have started to think about ways this could continue," Moriarty told The Sydney Morning Herald. "The producers have asked me to see if I can come up with some ideas. I wouldn't write a new book but perhaps a new story and then we'll see what happens. I'm absolutely open to it because, once I started thinking, it was too much fun to see what I could do and to see these characters again. And there's definitely places you can go."

The first thing Moriarty would do is "bring in more of Bonnie's story from the book," she said of the character portrayed by Zoe Kravitz on the HBO drama. "And also what happens next [for Kidman's Celeste]. That's the question that's also a really interesting thing, when you've been through a relationship like that, how do you feel now? How would she feel? She's grieving. She's still grieving for the end of a terrible relationship, and I think that would be a really interesting thing to explore. So there's a whole lot of different storylines."

The author also noted that she's heard positive feedback from the cast, with star and executive producer Witherspoon lobbying for more Big Little Lies. "I think everybody is pretty keen," said Moriarty. "They all loved working together, but I think the thing is the story has to be right. So if is right, and if [showrunner] David E. Kelley is happy to get the screenplay right, then I think that'll do it."

For his part, Jean-Marc Vallee — who directed the series — told The Hollywood Reporter after the finale that the HBO incarnation of Moriarty's book skipped Bonnie's backstory for a reason. "We had a line from the detective and it was too much explaining. We decided not even to shoot the line," he said. "Whether or not she has been abused, she is going to push this motherf—er. He's beating the shit out of four women. This guy is f—ing strong. And then the smallest guy pushes him, not to kill him, but the accident happens. To give it a reason and justify that because she was abused and had a thing against men, it's not about that."

Vallee also noted that he would not want a second season of the series. "Let's move on and do something else," he said. "If there's an opportunity to reunite with Reese, Nicole and these characters of course, I'll be a part of it, but Big Little Lies One is a one-time deal. Big Little Lies Two? Nah. The end is for the audience to talk about. Imagine what you want to imagine and that's it. We won't give you a season two because it's so good like this. Why spoil it?"

HBO has yet to announce any plans for a second season of Big Little Lies. The limited series, originally envisioned as a film, wrapped its run with an average haul of 7 million viewers over its seven-week arc — which was better than last year's breakout The Night Of. (And HBO is in talks for a second season of the latter.)
