A host of celebrities including Emma Thompson, Gillian Anderson, Mark Gatiss and Ian McKellen, are set to take to the stage in a farcical whodunnit at London’s Park Theatre.

Whodunnit [Unrehearsed] will feature a guest star every night of its run in the role of the inspector. They will have their lines fed to them via earpiece as they attempt to crack the case of a stolen diamond.

Every performance features the voices of Ian McKellen, Emma Thompson and Stephen Fry.

The confirmed list of actors set to play the role of the inspector include , Gillian Anderson, Clive Anderson, Sanjeev Bhaskar, Gyles Brandreth, Marcus Brigstocke, Simon Callow, Michelle Collins, Adrian Dunbar, Mark Gatiss, David Haig, Harry Hill, Adam Hills, Suranne Jones, Paterson Joseph, Ronan Keating, Ross Kemp, Maureen Lipman, Joanna Lumley, Lee Mack, Jason Manford, Stephen Mangan, Tim McInnerny, Ian McKellen, David Mitchell, Neil Morrissey, Tamzin Outhwaite, Sue Perkins, Clarke Peters, Tony Robinson, Hugo Speer, Meera Syal, Emma Thompson, Tim Vine, Johnny Vegas, and Bradley Walsh.

Writer and Director Jez Bond said: “Whodunnit [Unrehearsed] was such a success in 2019, we felt it was only right to bring back the concept; with an utterly new script. The support we have had from some of the very biggest names in film, TV, music and theatre has absolutely blown us away and we’re delighted and honoured to see a huge number of returning Inspectors as well as the terrific new ones who have come on board.”

Following the show, the audience will be given the chance to ask the celebrity questions about what they’ve just seen. Audiences can also win the chance to perform on stage with the mystery celebrity guest by entering a £10 ballot to play a small (but vital!) speaking role in the show. Entry is available when booking ticket or via the box office after tickets are purchased.
