An experimental play running at the Edinburgh Fringe probes the question of whether you can have theatre without actors. “Only two people at a time can participate in this work (there is no other audience; so much for the producer’s fantasy). It requires the audience-members-turned-actors to follow a recorded script and essentially perform for one another. The show, which makes the point quite creatively that every conversation is a performance, opened in London in February and has been performed in Portugal, Argentina, Germany, Norway, Italy and Minneapolis.”
