Even by Lars von Trier standards, this is a gloomy movie. But this 2011 drama is, if nothing else, visually evocative, and emotionally haunting. It also features some very unadorned and committed performances, starting with Kristen Dunst as the bride who may be witnessing a celestial disaster on her wedding night. But also, watch for some of the other members of the wedding party, including Kiefer Sutherland from 24 and Alexander Skarsgard from True Blood.
