There are fairy-tale elements here, but "Fanny and Alexander" is above all the story of what Alexander understands is really happening. If magic is real, if ghosts can walk, so be it. Bergman has often allowed the supernatural into his films. In another sense, the events in "Fanny and Alexander" may be seen through the prism of the children's memories, so that half-understood and half-forgotten events have been reconstructed into a new fable that explains their lives.

What's certain is that Bergman somehow glides beyond the mere telling of his story into a kind of hypnotic series of events that have the clarity and fascination of dreams. Rarely have I felt so strongly during a movie that my mind had been shifted into a different kind of reality. The scenes at night in the Jacobi house are as intriguing and mysterious as any I have seen, quiet and dreamy, and then disturbing when the mad Ismael calmly and sweetly shows Alexander how everything will be resolved.

The movie is astonishingly beautiful. The cinematography is by Bergman's longtime collaborator Sven Nykvist, who surrounds the Ekdahls with color and warmth, and bleeds all of the life out of the bishop's household.

The enormous cast centers on Helena, the grandmother, played by Gunn Wallgren (in a role once intended for Ingrid Bergman). Wallgren is full-lipped, warm and sexy, and her affection for Isak is life-giving; she was the best thing in the film, Bergman believed.

Emilie (Ewa Froling) is the most conflicted character in the story; she marries the bishop for love, is tragically mistaken about what kind of man he is, thinks she can protect her children, and cannot. Her visit to Helena is heartbreaking. The marriage of Gustav (Jarl Kulle) and Alma (Mona Malm) is open enough to permit an extraordinary scene in which Gustav discusses his affair with his wife and Emilie, and they all try to decide what would be best for the maid. The bishop (Jan Malmsjo) is a tragic and evil man, strict because he is fearful and insecure, cruel because he cannot stop himself, in agony because, he confesses to Emilie, he thought everyone admired him, and he realizes he is hated.

This is a long film, at 188 minutes plus an intermission. But the version Bergman prefers is longer still, the 312-minute version he made for Swedish television. Both are available on a Criterion DVD, which includes Bergman's feature-length documentary on the making of the film. To see the film in a theater is the way to first come to it, because the colors and shadows are so rich and the sounds so enveloping.

At the end, I was subdued and yet exhilarated; something had happened to me that was outside language, that was spiritual, that incorporated Bergman's mysticism; one of his characters suggests that our lives flow into each other's, that even a pebble is an idea of God, that there is a level just out of view where everything really happens.

Note: When Sight and Sound, the British film magazine, asked the world's directors and critics to select the best films of the last 25 years, "Fanny and Alexander" was third, after Francis Ford Coppola's "Apocalypse Now" and Martin Scorsese's "Raging Bull."
