Good news for folks like me who can’t wait for Lars von Trier’s newest, “Melancholia”: The trailer for the film is available on line at melancholiathemovie.com. Billed as “a beautiful movie about the end of the world,” it has a great cast: Kirsten Dunst, Charlotte Gainsbourg, Charlotte Rampling, John Hurt, Stellan Skarsgard, Udo Kier and Kiefer Sutherland. Way to go, Lars!
