EMILY BLUNT 'WORKING WITH MATT IS A JOY!

There's always plenty of laughs on set when the two stars join forces

She's just announced she's taking a break from acting for a year to spend more time with her kids Hazel, nine, Violet, seven, and husband, fellow actor John Krasinski, 43, but before she steps back, Emily Blunt, 40, is going out with a bang!

Critics are calling her new movie Oppenheimer - which tells the story of Robert Oppenheimer, the theoretical physicist who helped develop the first nuclear weapons - director Christopher Nolan's best film to date. Here, Woman's Day catches up with the British star to find out what it was like working with friends Cillian Murphy and Matt Damon...

What first made you want to be part of this project?

First of all, it's [director] Chris Nolan. That was more than enough to get me interested. And then I read the script and I couldn't put it down. I found it to be so extraordinarily emotional and immersive. It plays out like a horror movie and by the end I felt destroyed by it.

What can you tell us about your character in the film?
