WHODUNNIT (UNREHEARSED) 2

Park Theatre until March 12 parktheatre.co.uk

This fundraising spoof murder mystery features a surprise guest star each night who plays the hapless detective with a riotous twist – they haven’t seen the script and their lines come via an earpiece.

Ian McKellen, Stephen Fry, Emma Thompson, Joanna Lumley and Gillian Anderson are just some of the big names lined up.
