I've long suspected that the primary appeal of Lar's von Trier's work stems from its amplified morbid curiosity factor (Antichrist's autoclitoridectomy being a prime example). At first glance, Melancholia - his upcoming title - seems less gore-centred, concerning itself instead with a marraige-meets-apocalypse theme.
True to form though, von Trier has managed to conjure controversy around the film, by way of some slightly baffling, seemingly Nazi-sympathetic comments. Despite his subsequent apology, it raised a tricky question around that nebulous boundary between artistic freedom and deliberate obnoxiousness.
Also interesting, is the fact that the movie opens on what is quite literally a controversial note, with the prelude from the opera Tristan und Isolde - the pugnacious Wagner having been similarly associated with possible antisemitism.
Contentions considered, here's the official trailer:
