The drama is really heating up on HBO series The Undoing as we get closer to revealing who was really responsible for the brutal murder of Elena – and what involvement Grace and Jonathan might have had in the killing.


The series has aired over the last few weeks on Sky Atlantic in the UK, with the penultimate episode airing this week before the finale drops next Monday, and viewers have been captivated by the mystery so far.

The series is the latest from the team behind smash-hit drama Big Little Lies and sees Nicole Kidman and Hugh Grant play a married couple who are implicated in a murder investigation following the death of a mother at their son's school.

Grant stars in The Undoing cast as oncologist Jonathan Fraser, who last week was about to reveal some crucial information about the murder while appearing on a prime time chat show.

Meanwhile, fans have had many theories about the real identity of the killer, with everyone from Grace's father Franklin to the couple's son Henry being listed as a possible culprit.

Kidman is heavily involved in the glossy new series, not only taking the lead role as Jonathan's wife Grace but also serving as producer and even singing The Undoing theme song, a surreal cover of Dream A Little Dream.

Meanwhile, Grant told Digital Spy the new series challenged him in a unique way with its hard-hitting storyline: "There was quite a lot of heavy, emotional stuff for me to do around family in this series, and I'm not sure I've ever had to do that in quite the same way before.

"And it did help enormously now that I have a wife and kids that I love and was separated from when I was shooting, so it was quite raw, some of, that for me."

In our The Undoing review, praised the show for being a well made and engaging drama, but questioned whether more experimental creative choices should have been made.

Nicole Kidman stars in The Undoing on HBO/Sky Atlantic

The series follows Grace and Jonathan Fraser, played by Nicole Kidman and Hugh Grant – an affluent couple living the high life in New York with their teenage son Henry. (Noah Jupe).

All seems rosy in their marriage until news breaks of a murder – the victim being Elena, a mother at Henry's school whose son was previously treated by Jonathan in his profession as an oncologist.

As the police begin to investigate, Jonathan becomes a key suspect, in no small part because it comes to light he had been having an affair with Elena and had visited her in her apartment shortly before she was found dead.

After briefly fleeing the city, Jonathan returns to profess his innocence, but even if he is able to get out of the murder charge, it seems it's too late to save his marriage to Grace, who has also been repeatedly questioned by the police and has now learnt of her husband's affair.

The drama is based on the novel You Should Have Known, by Jean Hanff Korelitz. Kidman reunites with Big Little Lies creator David E Kelley, who is on-board as writer and showrunner for The Undoing; he's joined by The Night Manager's Susanne Bier as the director.

Grant has teased the “creepy” inspiration he used to prepare for the role of the "smooth" oncologist, expressing his distrust of doctors' bedside manners.

“That sort of smooth and marvellous way a doctor approaches a patient, relaxed and calming and smooth and elegant, and in a way, too good to be true. A saviour. I’ve always found that creepy,” he laughed.

The Undoing reviews

In a four-star review, called The Undoing an entertaining thriller, but criticised it for not making more experimental creative decisions.

The casting of Hollywood A-listers Nicole Kidman and Hugh Grant proved somewhat distracting, as neither actor was able to fully disappear into their roles.

Fortunately, thanks to a sturdy script and an intriguing murder mystery, The Undoing is able to succeed regardless, although crime drama fans will be all too familiar with its simple structure.

Generally, reviews for The Undoing have been positive, but some critics have taken issue with its slow pace and lack of thought-provoking themes.

Some viewers on Twitter have been captivated by the mystery straight off the bat.

While others still need some convincing.
