"I loved this show. I was addicted to it. I thought it was an amazing exercise in what we know and don't know about people - about family, about friends, about how we flirted with the mystery of things," Streep said on Friday.

"I wanted to do it to be in that world. The world they created was amazing."

In the seven-episode season beginning in June, Streep plays Mary Louise Wright, mother-in-law to Nicole Kidman's Celeste, whose abusive husband, Perry, died at the end of season one.

David E. Kelley, who wrote both seasons, joked that the much-acclaimed Streep had to pass muster to get the role.

"We looked at Meryl's demo reel," Kelley told a TV critics meeting.

He noted that the character of Mary Louise was created by Liane Moriarty, whose novel Big Little Lies was adapted for the original season.

Nicole Kidman and Reese Witherspoon return as executive producers and stars of the drama set in Monterey, California.

Returning co-stars Laura Dern, Zoe Kravitz and Shailene Woodley comprise the so-called 'Monterey Five circle', joined together by dark secrets.

"We had such a good time doing it, and the desire to spend more time together had a lot to do with it," said Kidman, explaining the drama's return.

"Also, there was an enormous demand from the audience. It was generated by the audience, and the desire to see these people still in existence."

She noted the rarity of a series with so many female leads - let alone produced by and, this season, directed by a woman, Andrea Arnold - and the cast said the camaraderie they enjoyed last season was repeated.

Asked who proved the best storyteller in their off-camera moments, Streep's co-stars chorused, "Meryl!"

Streep modestly waved off the compliment, then added: "What happens in Monterey, stays in Monterey."
