HBO’s new all-star murder-mystery series The Undoing isn’t giving much away

Off the back of this first trailer, we're absolutely hooked.

Okay, let us take a look at who is involved in The Undoing. In front of the camera: Oscar-winner Nicole Kidman. Should've-won-an-Oscar-for-Paddington-2-role Hugh Grant. Oscar-winner Donald Sutherland. Golden Globe-nominee Edgar Ramirez. Behind the camera: directed by Susanne Bier (The Night Manager, Bird Box), and created and executive produced by David E. Kelley (Big Little Lies, Mr. Mercedes). And then you've got HBO's own official description of the show, which will set off those parts of your brain that immediately want to untangle a mystery: "Nicole Kidman and Hugh Grant star as Grace and Jonathan Fraser, who are living the only lives they ever wanted for themselves. Overnight a chasm opens in their lives: a violent death and a chain of terrible revelations. Left behind in the wake of a spreading and very public disaster and horrified by the ways in which she has failed to heed her own advice, Grace must dismantle one life and create another for her and her family." Kidman reuniting with her Big Little Lies producer, and bringing along a newly-career-revitalised Hugh Grant (who was also a highlight in recent outing The Gentlemen), and we are fully on board for a new brain-twisting mystery. The Undoing will debut on HBO (in the States) and Sky Atlantic/Now TV (in Ireland) in May. Clip via HBO
