Oxford Playhouse is delighted to announce a brand-new staging of Hugh Whitemore’s acclaimed play Breaking the Code, with full cast revealed.

This production, a collaboration between Oxford Playhouse, Royal & Derngate, Northampton, and Landmark Theatres, in association with Liverpool Everyman & Playhouse and HOME, will be performed at the Oxford venue from Tuesday 7 to Saturday 11 October 2025.

Based on the book Alan Turing: The Enigma by Andrew Hodges, the play follows mastermind Alan Turing’s career as a visionary mathematician and codebreaker and examines how society’s attitude towards his sexuality changed the course of his life.

For the first time the revival will feature new material that speaks to Turing’s lasting legacy for modern Britain and the development of Turing’s law, with a new epilogue by Neil Bartlett that takes into consideration Turing’s Royal pardon in 2013.

The role of Alan Turing will be played by Mark Edel-Hunt (Leopoldstadt, West End). The cast also includes Niall Costigan (The Railway Children, Hull Truck Theatre) as Mick Ross, Joseph Edwards (The Red Shoes, Royal Shakespeare Company) as Christopher Morcom & Sixth-Former, Peter Hamilton Dyer (The Promise, Chichester Festival Theatre) as Dillwyn Knox, Carla Harrison-Hodge (Cyrano de Bergerac, Jamie Lloyd Company) as Pat Green, Susie Trayling (Harry Potter and the Cursed Child, West End) as Sara Turing/Smith, and Joe Usher (Falkland Sound, RSC) as Ron Miller & Nikos.

The production is directed by Jesse Jones (Education, Education, Education Royal & Derngate/The Wardrobe Ensemble) with set and costume design by Jonathan Fensom (The Two Popes, Royal & Derngate). Johanna Town (The Comedy About Spies, Mischief/West End) is the lighting designer, and Robin Colyer (The King’s Speech, Watermill Theatre) is the sound designer and composer. They are joined by Gerrard Martin as movement director, Hannah Miller as casting director and Gemma Boaden as voice & dialect coach.

Mastermind. Code breaker. Maverick. Arguably one of the most important and inquisitive minds of the twentieth century. Alan Turing is famed for cracking the Enigma code at Bletchley Park, effectively securing victory for the Allied forces in WWII.

From triumph to tragedy, get to know a human being who loved, lost and never stopped asking questions in a quest for truth and understanding in this new production of Hugh Whitemore’s Breaking the Code.
