I had an illustration of that some years ago when some young actors, who had been used to working in a 200-seat house with a 35-foot proscenium opening, were translated into a 600-seat house with a 70-foot proscenium for a production of The Importance of Being Earnest. Jack and Algy had, at first, the greatest difficulty in accepting that they could still carry on a close relationship while sitting 15 feet apart.
