NICOLE Kidman has admitted to feeling the strain of filming the second episode of The Undoing and its “emotional” twist.
In the latest episode of the psychological thriller, therapist Grace Fraser (Kidman) is confronted by her fugitive husband Johnny – played by Hugh Grant.

His character has been on the run after Grace found out he was living a double life – and may have murdered his lover.
The star told TV Line how she was left emotionally fragile after filming – and being on a short time scale to film the charged scene.
She said: “I was pretty strung out by that stage, just by the nature of being in a whole series and the emotional journey that Grace goes on.
“It was interesting because it was so palpable. Hugh and I were both strung out. So the idea that there was this clock ticking… we just had to jump in and do it.

“I am very much a performer who goes, “OK, let’s do it. Let’s capture the magic, if there is any.” And that’s what we had to do in that regard.”
The award-winning actress opened up about the intensity of filming and how it effects her home life while applauding director Susanne Bier’s vision.
Nicole said: “I’ll go home and night and my dreams will be affected and my whole life gets affected.
“But that’s my artistic choice and that’s my commitment to what I do.”

“And Susanne is like that. So I was like, ‘Whatever you need to do to tell this story so that people will feel it.
“Not just watch it from a distance but go on a journey and feel it.’ That’s what we hoped for.”
In the second episode in the series, Grace had discovered Jonathan had been having an affair, he lost his job and he was also suspected to be Elena’s killer.
After admitting to Grace he had been cheating on her with Elena, Jonathan said he went to Elena’s studio to confront her because he felt she was getting too close to his wife.

The pair argued which lead to them sleeping together, and he then decided to go to a bar. When he returned, he claimed Elena was already dead.
There are six episodes in the gripping series about murder combined with tantalising sexual tension.
However, fans have recently backflipped over who they think is the killer in the hit drama, calling it “b****y obvious”.
