Brand new first time celebrity guest sheriffs announced, including Adjoa Andoh, Liz Carr, Julian Clary, Kerry Ellis, Chris McCausland, Michael Palin, Alison Steadman, Cathy Tyson, and David Suchet – with many more still to be announced.
Artistic Director Jez Bond, Executive Director Catherine McKinney, and the whole team at Park Theatre today announce a further wave of celebrity guest sheriffs for Whodunnit [Unrehearsed] 4, the next instalment of its hugely popular fundraising comedy spectacular, which returns from 11 May – 27 June 2026 with the most ambitious version yet.
At every performance, a different celebrity will take on the central role of Sheriff – completely unrehearsed! Armed only with an earpiece feeding them lines moments before they speak, each guest must attempt to solve the murder, survive the mayhem and keep the show on track, while the audience watches events spiral in gloriously unpredictable ways.
Making their Whodunnit debuts this year will be Adjoa Andoh, Liz Carr, Julian Clary, Kerry Ellis, Chris McCausland, Michael Palin, Alison Steadman, Cathy Tyson, and David Suchet. They join previously announced returning guest sheriffs Gillian Anderson, Sanjeev Bhaskar, Jim Broadbent, Hugh Bonneville, Adrian Dunbar, Emma Thompson and Sandi Toksvig, with Sir Ian McKellen returning to lend his voice to the chaos.
Set in the lawless Wild West town of Graveside, Whodunnit [Unrehearsed] 4 will see Park Theatre transformed into a fully immersive world – taking over the entire building for the first time, from the street outside to the bars, foyers and both auditoria.
Accompanying the celebrity guest sheriffs in the cast will be Toby Baddeley (The Rivals and Twelfth Night with The New Forest Players and Antigone with Vienna’s English Theatre) as ‘Buck Steed’, Caroline Deverill (Whodunnit [Unrehearsed] 2 & 3 at Park Theatre, Typical Rainbow with Turbine Theatre), as ‘Dawn Frencham’, Gabriel Fogarty-Graveson (The Co-op at Park Theatre and English Theatre of Hamburg, Our Little Life at the Black Box Studio, Slovenia, The Merry Wives of Windsor with OVO), as ‘Jim Ranson’, Iona Fraser (The Creakers, Southbank Centre / Theatre Royal Plymouth, The Play That Goes Wrong, Duchess Theatre, Dear Evan Hansen, West End), as ‘Verity Hargreaves’, Edward Kaye (multi-instrumentalist making his London theatre debut) as ‘James Early’, Ian Oakley (Dracapella, Park Theatre, The Color Purple, UK Tour) as Willy the Pianist, Matthew Romain (The Curious Case of Benjamin Button, Ambassadors Theatre, The Score, Theatre Royal Haymarket, Grapes of Wrath with National Theatre) as ‘Rev. Virgil’ and Susanna Wolff (Whodunnit & her one-woman show Totally Fine, Park Theatre) as ‘Meg Frencham’.
Whodunnit [Unrehearsed] 4 is a vital fundraiser for Park Theatre, which receives no regular public subsidy. Proceeds from the production directly support the running of the building, the development of new work, and the theatre’s extensive community and education programmes – helping Park Theatre remain an accessible, creative hub for artists and audiences alike.
For 2026, audiences will step straight into Graveside the moment they arrive, with the exterior of the building reimagined as a Wild West streetscape, and both levels of the theatre’s bars dressed with hay bales, whisky barrels and Old West décor. Studio space Park90 becomes The Last Chance Saloon – an exclusive immersive space for cabaret seat and Band A+ ticket holders. Here, audiences will find themed drinks, nibbles, live music, roaming characters and mock gambling, alongside a dedicated cloakroom and bar.
A fully themed food and drink offer completes the experience, with a selection of Old West-inspired cocktails available to enjoy.
Jez Bond, co-writer & director, and Park Theatre’s Artistic Director said, “We are absolutely delighted to welcome these incredible new guest Sheriffs to Park Theatre; The generosity of the artists who agree to throw themselves into Whodunnit [Unrehearsed] — completely unrehearsed — never ceases to amaze me.
We never announce which celebrity is performing on which night, because the surprise is part of the fun. Book a ticket and you’re guaranteed someone extraordinary — a national treasure, a comedy icon or a stage legend — stepping into the boots of the Sheriff and flying by the seat of their chaps.
Every performance is different, gloriously unpredictable, and every single one helps support Park Theatre. It’s high-wire theatre with a serious purpose behind it — and that’s exactly what makes it so thrilling.”
Further celebrity Sheriffs will be announced.
