Naomi Watts has opened up about emotional journey of filming new movie The Impossible.
The action thriller is based on true events, and tells the story of a family's experience of the 2004 Indian Ocean tsunami.
Naomi plays Maria Belton, who survived the 2004 Boxing Day disaster.
Speaking to US news programme Entertainment Tonight, the star admitted the role took an emotional toll on her.
She recalled how she was brought to tears during a screening.
"I actually got truly swept up with this," she said.
"I remember watching the news with total horror, and staying glued to it and watching the numbers grow and grow, it was horrific."
One of the most emotional moments came when Naomi met Maria in person. The actress admitted she was at a loss for words.
"I was very nervous about meeting her because I thought, where do I begin this dialogue, what do I say, what shall I ask her," Naomi recalled.
"But we sat in a room and I looked at her and thought, oh, please let her begin, and she just started welling up, and the story was told in one look, and I felt immediately connected to her."
Naomi is nominated for a Golden Globe and a Screen Actors' Guild Award for her performance in the Juan Antonio Bayona film.
She's trying her best not to get swept up into awards season buzz.
"It makes you nervous, definitely," she admitted.
