'Big Little Lies' was emotionally draining: Nicole Kidman

Actress Nicole Kidman said she found filming TV series "Big Little Lies" to be emotionally draining.

The 50-year-old actress said it was tough to return to her home life with husband Keith Urban and their two children - Sunday, nine, and Faith, six - after some gruelling days on the set of the dark comedy-drama mini-series, reported Entertainment Tonight.

The Academy Award-winning star - who played Celeste Wright on the acclaimed HBO show - said, "Because we were shooting for so long... I think the duration of (the production) slowly started to seep in.

"Normally I can step back into my family life in a very easy way. I mean, not always, but you know, usually. I've been working a long time now. But it was hard.
