Provocative Danish director Lars von Trier says he fears he won't make any more movies since sobering up, because his award-winning films were made while intoxicated.

In his first interview in three years, von Trier told Saturday's edition of Danish daily Politiken that he no longer drinks a bottle of vodka a day or takes "narcotics" that had helped him enter "a parallel world."

Because of sobering up, von Trier says: "I don't know whether I can make more films. And that haunts me."

In 2011, the director of "Nymphomaniac" and "Breaking the Waves" was ejected from the Cannes Film Festival after expressing sympathy with Adolf Hitler. He later said he had been joking, and said he would no longer speak in public.
