When I say sleep, you’re free again. A rare chance to see Tim Crouch's ground-breaking classic. When it opened in 2005, An Oak Tree changed the rules of the game, bringing into the action an actor who hasn’t seen or read the play. In a performance of controlled virtuosity, the playwright guides that actor through a story of loss, suggestion and the power of the mind. No two shows are the same, with a different guest actor revealed each night. Previous guests include David Tennant, Jessie Buckley, Frances McDormand, F Murray Abraham, Russell Tovey, Phoebe Waller-Bridge, Meera Syal and many more.
