The Mousetrap Enters 75th Year with New Cast and Director

The world’s longest-running show has plenty to celebrate as it enters its 75th year in the West End. The production recently saw a refurbishment of the historic St. Martin’s Theatre, its long-time home, and now welcomes a new director and company.

As Agatha Christie’s The Mousetrap approaches 75 years in the West End, producer Brian Fenty has announced plans to mark the anniversary of the longest-running show in the world. Hannah Chissick takes the helm as the new director, as a new company joins the production. The set, lighting and sound have also been redesigned.

The historic St Martin’s Theatre has also seen a refresh, with redesigned bars and decorative details inspired by the world of Agatha Christie across the Stalls, Dress Circle and Upper Circle. Mr Lyan Studio will craft a bespoke cocktail menu created exclusively for the venue.

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. As news spreads of a murder in London, seven strangers are snowed in at Monkswell Manor, a remote countryside guesthouse. When a police sergeant arrives, the guests discover that a killer is in their midst. One by one, the suspicious characters reveal their sordid pasts. Which one is the murderer, and who will be their next victim?
