Gillian Anderson and Damian Lewis among stars appearing in Park Theatre murder mystery show

Gillian Anderson, Jim Broadbent, Joanna Lumley and Damian Lewis are among the performers lined up to appear, unrehearsed, in a murder mystery production at London’s Park Theatre.

Whodunnit [Unrehearsed] will feature a different guest performer each night, who will join a rehearsed ensemble of a scripted murder mystery play, having not rehearsed, received any direction or seen the script prior to performance.

The unrehearsed performer will wear an earpiece during the performance to receive instructions and will attempt to solve the crime during the show.

Guest performers also include comedians John Bishop, Catherine Tate, Tim Vine and Ruby Wax, as well as Clive Anderson, Gyles Brandreth, Marcus Brigstocke, Simon Callow, Ronan Keating, Maureen Lipman, Juliet Stephenson and Meera Syal.

The play will be narrated by the voices of Ian McKellen and Judi Dench.

The production is being staged by Park, which is unfunded, to raise money for its operation.

It is being presented in association with comedy producers Avalon and will run at Park from July 15 to 27 before transferring to the Edinburgh Festival Fringe from July 31 to August 26.

Performers for the Edinburgh run are yet to be announced.

Anderson said: “I’m performing at Park Theatre to help raise funds for the charity. With no public subsidy, they need to fundraise over £250,000 a year just to keep the doors open. The monies raised from this production’s higher ticket prices will support their core ambition to present accessible theatre over the coming years and to further their work with the local community.

“A number of £10 day tickets will also be available. I do hope people will come and enjoy, and reap the benefit of supporting this fantastic cause.”

The production will be directed by Park’s artistic director Jez Bond.
