THE MOUSETRAP ENTERS ITS 75TH YEAR IN THE WEST END

As Agatha Christie’s The Mousetrap approaches 75 years in the West End, and its UK and Ireland tour continues to bring the iconic production to audiences nationwide, producer Brian Fenty announces plans to mark the anniversary of the longest-running show in the world. The plans include Hannah Chissick taking the reins as director of the West End classic, with a new company of actors joining the production as well as revitalised set, lighting and sound redesign, and a refurbishment of its historic home, St Martin’s Theatre. The milestone will be celebrated with a Gala Performance at St Martin’s Theatre on 25 November 2026.

With Chissick’s production of The Mousetrap on its UK and Ireland tour, she will now direct the new West End cast. The new cast is Marcus Adolphy as Major Metcalf, Jonathan Cobb as Detective Sergeant Trotter, Rosa Coduri-Fulford as Miss Casewell, Dean Graham as Mr Paravicini, Dan Nicholson as Giles Ralston, Jake Rory as Christopher Wren, Gay Soper as Mrs Boyle, and Sarah Twomey as Mollie Ralston. The new cast begin performances on 11 November 2026.

The new production features set design by Walt Spangler, lighting design by Nic Farman and sound design by Max Perryment.

Inspired by Christie’s radio play Three Blind Mice, first broadcast on 30 May 1947, The Mousetrap was first staged in the West End on 25 November 1952 and has firmly established itself as one of British theatre’s most enduring institutions. This anniversary will bring a new look and feel to the production, while honouring Christie’s original text with its masterful storytelling that has captivated generations of audiences. The play is currently one of only two plays in the West End written by women, while for the majority of its historic run it was the only one.

• The celebrations will extend beyond the stage, with redesigned bars and decorative details inspired by the world of Agatha Christie to feature across the Stalls, Dress Circle and Upper Circle.
• Studio Shayne Brady will refresh the interiors of St Martin’s Theatre, while
• Mr Lyan Studio will craft a bespoke cocktail menu created exclusively for the venue.

Brian Fenty, producer of The Mousetrap, today said, “As we approach the extraordinary 75th year of The Mousetrap, we have made a substantial investment in the production, its historic home at St Martin’s Theatre and the entire audience experience, ensuring this theatrical treasure shines with all the brilliance of its opening night in 1952.

“To be entrusted with this remarkable piece of theatre history is both a privilege and a responsibility. Agatha Christie’s genius lies in the extraordinary detail of her storytelling: the wit, the atmosphere and the suspense that have kept generations of audiences guessing. Every element of our investment - from the loving refurbishment of the theatre to the care devoted to the set, lighting, effects and direction - serves her storytelling.

“As we welcome our wonderful new cast, our ambition is simple: to honour everything that makes The Mousetrap iconic and ensure it feels as thrilling for audiences today as it did when the curtain first rose.”

Hannah Chissick added, “I am so honoured to be joining The Mousetrap as director, especially as the show enters its incredible 75th year in the West End.

“Agatha Christie’s storytelling remains as vibrant, entertaining and engaging as it was when the play first came to the stage. Now, working with this exceptional new cast and creative team to bring it to life is a joy. Every detail, from the set to the lighting and sound, has been given the thought and devotion this play inspires, so that it can continue to be enjoyed for generations to come, and I can’t wait to share it with audiences at St Martin’s Theatre.”
