Conor McPherson’s The Weir is currently playing at the Donmar Warehouse. It’s the first major revival of an undoubted modern classic, directed by Josie Rourke.

On its premiere in 1997, at London’s Royal Court, The Weir won the Evening Standard Critic’s Circle and Olivier Awards for Best New Play.

Set in a rural bar in Ireland, a publican and three of his regulars attempt to spook a newcomer from Dublin, but end up frightened themselves.

My sketch was signed by Dervla Kirwan, Brian Cox and Father Ted’s Ardal O’Hanlon on Saturday 4 May.
