Into the opulent home of Hirst, a wealthy, noted man of belle lettres, comes Spooner, a shabby, beer-spotted poet. As the alcohol flows and the night wears on, the lines of reality blur as we move with Hirst into a mindbending limbo, a relentlessly cynical arena of self-doubt. Playwright Harold Pinter contructs a milieu of eternal truths and rising uncertainty, a world that adroitly questions where one’s reality begins and another’s ends. Richard Romagnoli directs No Man’s Land, running in repertory at the Potomac Theatre Project.
