The most divisive director working today could arguably be Lars Von Trier and whether one considers him as someone who sets out to shock or not, he manages it either way. His latest caused a large walkout at Cannes, where he had seven years previously been banned, but managed to be readmitted. All is forgiven? Not quite, it seems. So, down to the film in question: The House that Jack built. Named after a Metallica song, some might not expect much from such meagre beginnings.
