Whodunnit Unrehearsed 4 at Park Theatre this Summer

Welcome to Graveside — a lawless town where the entire theatre becomes one fully immersive western world. This is Whodunnit [Unrehearsed] 4. And every single night, a different celebrity steps in as Sheriff, completely unrehearsed.

The initial 2026 cast list is out with Sir Ian McKellen, Gillian Anderson, Emma Thompson, Adrian Dunbar, Jim Broadbent, Sandi Toksvig, Sanjeev Bhaskar and Hugh Bonneville all throwing their hat into the ring to be Sheriff.

They’ll have no script. Just an earpeice. Their job? Solve the murder, survive the chaos, and somehow keep the show together — while everything spirals wildly out of control. It’s theatre, but not as we know it.

Catch performances at Park Theatre, Finsbury Park from 11 May – 27 Jun 2026. More information and tickets here.
