Stevie, too, often speaks directly to us, just as easily as she speaks to others on stage, simply by looking at us. [....] In the film, the "us" is of course the camera. This is hardly a new device, but in serious work, it's always a bit risky. It can smell of false naiveté, treating the technology of production and the pastness of the film as if they didn't exist—a risk that doesn't apply in the relatively untechnological, present-tense theater.Stanley Kauffmann, "Stevie," Field of View.
But that risk never bothers Stevie, and not just because the writing is limber and the address to the audience uncoy. It's because the presence of the audience is taken absolutely for granted. That acceptance is no mere dramaturgic device: it involves metaphysical truth about Stevie herself. It's as if our presence had always been part of the woman's life. What the audience was in the theater, what the camera is here, is the witness that every artist needs to perceive all his secrets whole, secrets that even his nearest and dearest cannot wholly see. His art is the externalizing of only some of those secrets: but all of them need witness. (Somewhere Auden said that, when he arrives in Heaven, God will walk toward him speaking lines of the poems he never wrote.) Stevie says firmly that she is an agnostic. This is relevant to the method of the play and the film. A devout believer wouldn't need to address us so much, she would have a witness of all her secrets.
