Tom Chambers joins Giovanna Fletcher in Before I Go To Sleep tour

The stage adaptation of Before I Go To Sleep has added further cast.

S J Watson’s novel follows Christine, who appears to live an idyllic life, except that every night when she falls asleep, she loses all memory of the last 20 years. As she attempts to piece her life back together, terrifying truths emerge. It was adapted into a hit film starring Nicole Kidman and Colin Firth.

As already revealed, Giovanna Fletcher will lead the world premiere stage show, written by Rachel Wagstaff and directed by Loveday Ingram. They previously collaborated on The Girl on the Train.

Joining her, Tom Chambers will play Ben on the UK and Ireland tour. He said: “I’m absolutely thrilled to be joining Giovanna in Before I Go To Sleep. It’s such a brilliantly unsettling story, and what I love about it is that you’re never quite sure who or what to believe.”

The actor added: “Ben is a fascinating character to play, particularly in a story where memory and trust are so closely intertwined. I think Rachel has done a great job adapting the book into a stage play and I can’t wait to get into rehearsals and bring this extraordinary thriller to audiences around the country.”

A sequel to the novel will also be released in 2027.
