Meryl Streep reveals why she joined 'Big Little Lies' season 2

Meryl Streep is opening up about why she decided to join the star-studded cast of "Big Little Lies."

Speaking to reporters during the HBO portion of the Television Critics Association Winter Press Tour in Los Angeles on Friday, the three-time Oscar-winning actress revealed that she was actually a fan of the drama.

"I loved this show," Streep, 69, said. "I was addicted to it. I thought it was an amazing exercise in what we know and what we don't know about people, about family, about friends, how it flirted with the mystery of things, what was unsaid, unshown, unknown, was sort of the pull, the gravitational pull of the piece, and it was so exciting, so when I got the chance to join the crew, I thought yeah.

"I wanted to do it, to be in that world," she continued. "The world that was created was amazing."
