First-look production photos have been released for WHODUNNIT [UNREHEARSED] 4 at Park Theatre, featuring celebrity guest sheriff Gaby Roslin. The immersive comedy fundraiser is currently running through June 27, 2026.

The production marks the fourth installment of Park Theatre’s Whodunnit [Unrehearsed] series, which returns this year with a Wild West theme and an expanded immersive format taking over the entire venue. At each performance, a different celebrity guest appears in the role of Sheriff without rehearsal, receiving lines through an earpiece while attempting to solve the evening’s central mystery live onstage.

Additional guest sheriffs announced for the production include Benedict Cumberbatch, Martin Freeman, Ian McKellen, Damian Lewis, Simon Pegg, Meera Syal, and Jodie Whittaker. Newly announced performers making their Whodunnit debuts include Anne-Marie Duff, Toby Jones, Katherine Parkinson, Sara Pascoe, Iwan Rheon, Gary Wilmot, Suzi Ruffell, and Munya Chawawa.

Returning guest sheriffs include Amanda Abbington, Clive Anderson, Gyles Brandreth, Michelle Collins, Nina Conti, David Haig, Harry Hill, Adam Hills, Russell Kane, Matt Lucas, Gareth Malone, Gabriel Macht, Al Murray, Dermot O’Leary, Tamzin Outhwaite, Clarke Peters, Rob Rinder, Rhashan Stone, Bradley Walsh, Olivia Williams, Marcus Brigstocke, and Greg Wise. Previously announced guest sheriffs also include Gillian Anderson, Sanjeev Bhaskar, Jim Broadbent, Hugh Bonneville, Adrian Dunbar, and Emma Thompson, while Ian McKellen returns to provide voiceover narration.

Set in the fictional Wild West town of Graveside, the production transforms the theatre’s exterior, foyers, bars, and auditoria into an immersive environment centered around the mystery of missing gold. The production also includes themed food and beverage offerings, live music, roaming characters, and interactive elements throughout the building.

The cast accompanying the guest sheriffs includes Toby Baddeley as Buck Steed, Caroline Deverill as Dawn Frencham, Gabriel Fogarty-Graveson as Jim Ranson, Iona Fraser as Verity Hargreaves, Edward Kaye as James Early, Ian Oakley as Willy the Pianist, Matthew Romain as Rev. Virgil, Susanna Wolff as Meg Frencham, with Molly Barton and Killian Macardle in ensemble roles.

WHODUNNIT [UNREHEARSED] 4 serves as a fundraiser for Park Theatre, supporting the venue’s operations, new work development, and community and education programs.
