Lars von Trier has never run away from controversy. The Danish enfant terrible has rather made a career out of embracing it – whether by being banned from the Cannes Film Festival for fascist remarks or by tackling the lives of mentally challenged people in Idiots. Whereas his 2011 feature, Melancholia starring Kirsten Dunst, was a lugubrious ballad about the world’s end, Lars von Trier returns to his familiar stomping grounds of explicit sex and violence in his new double-dip Nymphomaniac with Charlotte Gainsbourg, Stellan Starsgård, and Shia LaBeouf.
