The highly ambitious and successful Justine (Kirsten Dunst) is celebrating her wedding. As the reception progresses, however, she can't seem to shake an overwhelming sense of dread. While she struggles to overcome problems of an internal nature, her sister Claire faces a much more cataclysmic problem threatening everyone she loves.
Lars Von Trier's Trilogy of Depression – including Melancholia, Antichrist and Nymphomaniac – is said to be his grand homage to Andrei Tarkovsky. When the film premiered at the 64th Cannes Film Festival (where Kristen Dunst was awarded Best Actress), Von Trier famously referred to Tarkovsky as his god, and to Mirror as his religion. The Tarkovskian universe is perhaps most apparent in the titular planet which makes its appearance in a breathtaking opening sequence, and torments the sisters throughout.
