Director Lars von Trier suffered from severe depression and psychophobia in 2007; depression has plagued him for several years. During his treatment, a theory told him by a doctor gave rise to the idea of this movie: Under drastic changes, patients with depression and depression tend to act more calmly, while "normal and happy" people are more likely to panic because depression patients think that bad things will happen early on and are mentally prepared; this concept Formed a very different reaction of the two sisters to another planet; the film puts the miracle of the human mind in a disaster under a microscope, rather than describing the actual laws of astrophysics or serving as a disaster film.
In the film, the collision between the planet Melancholia and the earth symbolizes a sweet pain like falling in love. The character of Justine who is melancholic and depressed has special talents that no one else has, sometimes even like a prophet. Its name comes from the French writer Marquis de Sade's 1791 novel "Ristina, or the misfortune of Yu Meide".
