It is a strange comment to make about a film set inside a prison, but “The Shawshank Redemption” creates a warm hold on our feelings because it makes us a member of a family. Many movies offer us vicarious experiences and quick, superficial emotions. “Shawshank” slows down and looks. It uses the narrator’s calm, observant voice to include us in the story of men who have formed a community behind bars. It is deeper than most films; about the power of the story you tell yourself about yourself and your situation.

Interesting that although the hero of the film is the convicted former banker Andy Dufresne (Tim Robbins), the action is never seen from his point of view. The film’s opening scene shows him being given two life sentences for the murder of his wife and her lover, and then we move, permanently, to a point of view representing the prison population and particularly the lifer Ellis ‘Red’ Redding (Morgan Freeman). It is his voice remembering the first time he saw Andy (“looked like a stiff breeze would blow him over”), and predicting, wrongly, that he wouldn’t make it in prison.

From Andy’s arrival on the prison bus to the film’s end, we see only how others see him – Red, who becomes his best friend, Brooks the old librarian, the corrupt Warden Norton, guards and prisoners. Red is our surrogate. He’s the one we identify with, and the redemption, when it comes, is Red’s. We’ve been shown by Andy’s example that you have to keep true to yourself, not lose hope, bide your time, set a quiet example and look for your chance. “I guess it comes down to a simple choice, really,” he tells Red. “Get busy livin’ or get busy dyin’.”

The key to the film’s structure, I think, is that it’s not about its hero, but about our fascination with him and his story- our curiosity, our pity, our admiration. If Andy had been the heroic center, bravely enduring, the film would have been conventional, and less mysterious. But we wonder about this guy. Did he really kill those two people? Why does he keep so much to himself? Why can he amble through the prison yard like a free man on a stroll, when everyone else plods or sidles?

It plays more like a spiritual experience than a movie. It does have entertaining payoff moments (as when the guards from another prison, wearing their baseball uniforms, line up to have Andy do their taxes). But much of the movie involves quiet, solitude, and philosophical discussions about life. The moments of violence (as when Andy is sexually assaulted) are seen objectively, not exploited.

The movie avoids lingering on Andy’s suffering; after beatings, he’s seen in medium and long shot, tactfully. The camera doesn’t focus on Andy’s wounds or bruises, but, like his fellow prisoners, gives him his space.

The Morgan Freeman character is carrier of the film’s spiritual arc. We see him at three parole hearings, after 20, 30 and 40 years. The first hearing involves storytelling trickery; the film has opened with Andy’s sentencing, and then we see a parole board, and expect it’s about to listen to Andy’s appeal. But, no, that’s when we first see Red. In his first appeal he tries to convince the board he’s been rehabilitated. In the second, he just goes through the motions. In the third, he rejects the whole notion of rehabilitation, and somehow in doing so he sets his spirit free, and the board releases him.

There’s an underlying problem. Behind bars, Red is king. He’s the prison fixer, able to get you a pack of cigarettes, a little rock pick or a Rita Hayworth poster. On the outside, he has no status or identity. We’ve already seen what happened to the old librarian (James Whitmore), lonely and adrift in freedom. The last act, in which Andy helps Red accept his freedom, is deeply moving – all the more so because Andy again operates at a distance, with letters and postcards, and is seen through Red’s mind.

Tim Robbins makes Andy a man of few words, quietly spoken. He doesn’t get real worked up. He is his own man, capable of keeping his head down for years and then indulging in a grand gesture, as when he plays an aria from Mozart’s “The Marriage of Figaro.” (The overhead shot of the prisoners in the yard, spellbound by the music, is one of the film’s epiphanies.) Because he does not volunteer himself, reach out to us or overplay his feelings, he becomes more fascinating: It is often better to wonder what a character is thinking than to know.

Some have said life is a prison, we are Red, Andy is our redeemer. All good art is about something deeper than it admits.
