I'm a big fan of existential folly in film, especially having completed many of my own. Zetterstrøm is the main character in this movie, a world-renowned pianist from Denmark. Since childhood, he is an assiduous "forgetter" of everything except his piano playing. This is to say that he stores up his disappointments, forgets them, and retreats behind a piano. After a love affair that ends due to his emotional constipation, he uses his facultative amnesiac skills once again, and this act is one step too far, so inimical to the fabric of reality, that a rent in reality is formed over three city blocks, and becomes referred to as the "Zone".
Zetterstrøm buries himself in his solitary existence of piano-playing, quite literally performing concerts in the dark, or behind screens so that the audience cannot see him. Shadowy figures draw Zetterstrøm back to the zone, unwilling to allow his non-confrontational existence to continue. Zetterstrøm must be made to confront his past.
It's a fascinating film, the narrator lets us know that it's Zetterstrøm's very brilliance which allows him to annihilate himself, that allows him to inoculate himself from reality.
I'm in absolute adoration of films that attempt to make visual metaphors of the human mind, such a film is this (the Zone fulfils this purpose), Tarsem films such as The Cell and The Fall are others. There is no subject more sacred, more revelatory as regards human potential. There's a scene where Zetterstrøm sits and has dinner in an ornately plastered ballroom. The windows and floor are all blacked out with plastic sheeting, and the room is covered in latched boxes loaded on pallets, representing Zetterstrøm's repressed past, there's also a cage with globes of light in, recognising the potentiality of his mind.
When there's narration we also see some very nice cartoons with Zetterstrøm as a child, that's another metaphor I'm very fond of from The Cell, that many of us are still children inside, just wounded, subdued, and with horrid barriers put up. You may have guessed that this movie moved me deeply.
