The Theatre Royal, Glasgow is delighted to announce that the brand-new stage production of Before I Go To Sleep will arrive at the venue from Tuesday 1 until Saturday 5 June 2027. Based on the international bestselling novel by S J Watson, which was later adapted into the hit film starring Nicole Kidman and Colin Firth, the production will star acclaimed actor, author and podcaster Giovanna Fletcher (The Girl on the Train, Everybody’s Talking About Jamie, 2:22 A Ghost Story) as protagonist Christine.
This gripping new stage adaptation is written by Rachel Wagstaff and directed by Loveday Ingram – the celebrated creative team behind 2025’s hugely successful stage adaptation of The Girl on the Train. Lighting Design will be by Jason Taylor, Tony Award nominee for his work on Journey's End at the Belasco Theatre, New York.
Giovanna Fletcher said: “I read the international bestselling novel Before I Go To Sleep and was hooked, so I can’t wait to take this play to the stage in 2027 on our UK and Ireland tour. It’s a thrilling, chilling and captivating story that I know audiences will love. I’m also chuffed to be working with Rachel Wagstaff and Loveday Ingram again - the three of us loved working on The Girl On The Train together last year and are very happy to be reunited.”
S J Watson said: "Before I Go To Sleep has lived many lives I never expected — and this feels like one of the most exciting yet. I can't think of a better team to bring Christine's story to the stage.”
The gripping production delves into the story of Christine, who appears to have an idyllic life - with one terrible exception. Every night, when she goes to sleep, she loses her memory. Every morning she wakes up remembering nothing from the last 20 years of her life - not even the loving husband lying next to her. As she desperately tries to piece her life back together, hidden and terrifying truths begin to emerge, forcing her to question everything and everyone around her.
Exploring the fragility of memory, identity and trust, Before I Go To Sleep is set to be a thrilling stage production packed with suspense, shocking revelations and edge-of-your-seat twists that will keep audiences gripped until its devastating climax.
Memories lie. People do too.
