Naomi Watts says that she knew The Impossible was going to be a big job but she wasn't quite prepared for just how big a job it was.
The Impossible follows one family's true story of being caught in the 2004 tsunami and their battle to survive.
The actress spent seven months filming the Juan Antonio Bayona directed movie as she reveals that they moved from city to city and country to country to get the shots that they needed.
In this new video the actress talks about the scale and the demand of the project that she calls 'a big experience:'
We may not have seen much of Watts on the big screen this year but the actress has been shooting a whole host of new movies.
She has completed work on ensemble piece Movie 43, Sunlight Jr and Two Mothers. She is also set to take on the role of Princess Diana in the movie Diana.
The Impossible sees the actress team up with actor Ewan McGregor and Tom Holland while Bayona is making his first movie since The Orphanage.
