The Park Theatre in London has announced more guest stars for its comedy fundraiser Whodunnit [Unrehearsed] 4.
Whodunnit [Unrehearsed] 4 is the fourth iteration of their successful comedy play, and is playing at the Park Theatre from 11 May to 27 June 2026.
The Wild West-themed show features a different celebrity guest Sheriff each night, who joins the fun completely unrehearsed, with only wits and wit to fall back on!
Sir Ian McKellen is back to lend his voice to the proceedings; and stars already announced as guest Sheriffs are Emma Thompson, Gillian Anderson, Adrian Dunbar, Jim Broadbent, Sandi Toksvig, Sanjeev Bhaskar and Hugh Bonneville.
Announced today, they will be joined by Adjoa Andoh, Liz Carr, Julian Clary, Kerry Ellis, Chris McCausland, Michael Palin, Alison Steadman, Cathy Tyson, and David Suchet.

In total, 63 celebrities will perform across the run, with further guest names to be announced. All of the celebrities are appearing unpaid, as Whodunnit [Unrehearsed] 4 is raising vital funds for the Park Theatre, which operates without any Arts subsidies. Their target is to raise £600,000.
More about Whodunnit [Unrehearsed] 4
The comedy is directed by the Park’s artistic director Jez Bond, and co-written with Bond and Mark Cameron.
The main cast of the show is Toby Baddeley (The Rivals) as Buck Steed, Caroline Deverill (Typical Rainbow) as Dawn Frencham, Gabriel Fogarty-Graveson (Our Little Life) as Jim Ranson, Iona Fraser (The Creakers) as Verity Hargreaves, Edward Kaye as James Early, Matthew Romain (The Curious Case of Benjamin Button) as Rev Virgil and Susanna Wolff (Everyone’s a Playwright) as Meg Frencham.
Whodunnit [Unrehearsed] 4 is set in Graveside, a dusty frontier town where the saloon and the general store look suspiciously similar, gold fever is running high, and (hobby) horses roam free. There’s stolen treasure, suspicious strangers, and a Reverend who may not practice what he preaches.
