" Nevertheless, he was caught in its magic and he understood, what he had not known before, that much of the magic of a great theatrical moment is created by the audience itself, a magic impalpable but vividly present, and that what begins as trickery of lights and paint is enlarged and made fine by the response of the beholders. There are no great performances without great audiences, and this is the barrier that film and television, by their utmost efforts, cannot cross, for there can be no interaction between what is done, and those to whom it is done. Great theatre, great music-drama is created again and again on both sides of the footlights. "

― Robertson Davies , The Lyre of Orpheus (Cornish Trilogy, #3)
