Steve Steen and Stephen Frost share a mutual ambition to improvise a play with no suggestions from the audience, bringing together like-minded performers to join them on stage to create a play from nothing. The Actor’s Nightmare is the result. The play might be a tragedy, comedy, melodrama, even a farce - nothing is planned in advance; the only thing that's certain is that this is the first time the play will ever be performed... and the last.
