Controversial filmmaker Lars Von Trier is testing movie fans once again with an explicit new clip for his provocative film Nymphomaniac.

The Scandinavian's two-part erotic epic will debut in his native Denmark on Christmas Day (25Dec13), and he has released a racy new teaser in which actress Charlotte Gainsbourg prepares herself for self-flagellation by exposing herself and bending over a chair.

The trailer starts with co-star Jamie Bell giving the actress' character a primitive sex toy made of wood and rope.
