Kristin Scott Thomas and Lily James are taking to the stage for the world premiere of Penelope Skinner’s Lyonesse at the Harold Pinter Theatre. Directed by Ian Rickson and also starring Doon Mackichan, James Corrigan and Sara Powell, the play, an exploration of who gets to control the stories we tell, follows reclusive actress Elaine (played by Scott Thomas) who, 30 years after she disappeared in mysterious circumstances, is ready for a comeback and enlists young film exec Kate (played by James) to help.
