Melancholia (2011) ✭✭✭
Las von Trier is one messed up individual. This is nowhere near as controversial as Antichrist, but his comments about Hitler and Nazis or whatever it was was certainly in my mind as I began watching this field.
Kirsten Dunst, Kiefer Sutherland, Charlotte Gainsborough, Stellan Skarsgard, and others make for an all-star cast. Udo Kier has a particularly great scene of comic relief near the beginning of the film.
Basically, a woman goes a little nuts before a rogue planet begins it collision path with Earth. I recommend you at least see it, although it's pretty bizarre.
