DC Moore’s Common at the National Theatre is described as an epic tale of England’s lost land. The revolving stage is covered in earth and the background is a huge cyclorama of sky. Jeremy Herrin’s production, designed by Richard Hudson and lit by Paule Constable, looks good on the vast, wide-open space which is the Olivier stage. The action takes place at the turn of the 19th century when rich landowners are appropriating public land for their own private benefit. England is in the middle of the Industrial Revolution and numerous Enclosure Acts (pure robbery) are being passed. The villagers are up in arms.
