It's still not decided: Nicole Kidman on 'Big Little Lies' S2

Actor Nicole Kidman says she is unsure when "Big Little Lies" will return for the second season.

The 50-year-old actor says the makers are taking their time so that the new spell matches the expectations of the audiences, reports E! News.

"It's still not decided because it is a lot to pull together.

"The first one was a lot to put together, so we are sort of not taking it lightly in terms of what it needs," says Kidman.

In April, actor-producer Reese Witherspoon confirmed the possibility of a second season of the HBO show.
