"Really, interactive stories are a deep and complex discipline in writing. Or at least it should be. And it one day will be an official one, distinct from others. But until then – because of the indirect reliance on audience participation, interactive writing does have an incidental relationship to good movies as well as theater, simply because projecting the audience’s thoughts to particular characters is such an important aspect of the technique.
For example, Shakespeare’s works frequently created setups that deliberately included the pool underneath the stage as a murmuring participant in the play itself. King Lear and Richard the Third both contain parts where the audience visiting the Globe would stand practically in the middle of the stage as the actors would fight over them, back and forth. In A Midsummer Night’s Dream, the play often dismisses the actors and suddenly directs an abstract speech specifically directed at the audience; the playwright is instructing the audience to see a relationship between the words and events that the characters themselves remain blind to. Later, the play ends as Puck directly addresses the audience, urging them to remember the play between the actors as if it has only been a dream. Their dream, not the writer’s dream."
