Melancholia

Kirsten Dunst gives a great performance in this film as Justine, who is suffering from depression, or melancholia.  It is a shock to see the face that was so animated as Mary Jane in Spiderman looking so expressionless.
But the film is more than about depression, as Melancholia is also the name of a planet, several times bigger than earth on an erratic orbit that swings close to earth. When scientists disagree as to whether the planet will swing close to earth "Fly by" or swing back and crash into earth, "Dance of Death" it has the ingredients of a disaster movie. But it is not that kind of movie and the Kiefer Sutherland character is no Jack Bauer.
All the action takes place at the rather grand home where Claire, played by Charlotte Gainsbourg, lives with her husband and son. They put on a great party for her sister Justine on her wedding day, and become increasingly embarrassed by her erratic behaviour. The opening scene sees the newly weds arriving late when their limousine is too long for the tight bend in the driveway.
To be fair to the bride, her father, mother and father in law, who is also her employer, would have been embarrassing enough even if her behaviour had been exemplary.  If you feel for Claire's embarrasment, it is excruciating, if you just enjoy a dysfunctional party, it is great.
After the party, it is just the two sisters, and Claire's husband and son, and the two horses. The first half was entitled "Part One:Justine" and this is entitled "Part Two:Claire" I am not sure why, they all have different responses to the impending doom, and that includes the horses. Perhaps Justine's is the most sane after all.
We know the end from the beginning. There is a superb opening sequence, comprising a series of still pictures or very slow moving video, set to beautiful music from Wagner (I think).  The images are bewildering or disturbing, but find their meaning as the film develops.
