New series Adultery for ITV will star Dominic Cooper (pictured) and Romola Garia

ITV has announced the leads and cast for upcoming Danny Brocklehurst series Adultery. The series will also star Shelley Conn, Matthew McNulty and more (see below).

What is Adultery about?

The announcement linked above has plenty to tell us:

The provocative love story raises questions about class, grief and the effects of social media, as it takes the viewer on a rollercoaster story of passion, parenthood and peril, as Tom Kirkman and Beth Brookes embark upon a passionate and intense love affair that threatens to uproot their whole lives. Adultery is naturally authentic and bristling with passion as it focuses upon two ordinary families and messy complications.

The show introduces us to Tom’s 15-year-old daughter Jess who has found love with schoolmate Ollie, and they can’t take their hands off one another, as love’s young dream becomes all consuming. When Tom meets Ollie’s Mum Beth in the most unexpected of circumstances, the two families’ lives are potentially turned upside down forever. Will Tom and Beth be able to control their desires unlike their lovestruck teenagers?

As to the casting, we also have a lot of detail on that: Dominic Cooper (Preacher, The Devil’s Double) and Romola Garai (One Life, Vigil) play the lead protagonists Tom Kirkman and Beth Brookes, who share an immediate, intense connection. As they struggle with their undeniable desires, the pair must grapple with their guilt and the potential consequences for their families. Also starring in the series are Shelley Conn (Gen V, Bridgerton) as Tom’s wife Hannah, and Matthew McNulty (Domina, Deadwater Fell) as Beth’s husband Neil. And introducing rising star Johnny Sanpher and Leila Khan (Heartstopper, Crookhaven) who will play teenage lovers, Jess Kirkman and Ollie Brookes.

Andrew Knott (Gavin & Stacey, Protection) will also be joining the cast as Dave, the ex-husband of Beth’s recently deceased best friend, alongside James Murray (The Crown, Masters of the Air) and Charley Webb (The Long Shadow, Better) as Paul and Leah Kirkman, Tom’s brother and sister-in-law.

The six-part series has started filming in Manchester. We assume it will be show in 2026. We’ll bring you updates as we get them.
