COPENHAGEN (AFP) - Danish film director Lars von Trier on Monday rejected Icelandic pop singer Bjork's allegation that he sexually harassed her during the making of the movie Dancer In The Dark.

"That was not the case. But that we were definitely not friends, that's a fact," he told Danish daily Jyllands-Posten in its online edition.

In a post on her Facebook page on Sunday, the singer-songwriter said she was inspired to speak out by the flood of allegations against US producer Harvey Weinstein.

She said she "became aware" that "it is a universal thing that a director can touch and harass his actresses at will and the institution of film allows it".

The 51-year-old musician, a former lead singer of The Sugarcubes post-punk group, did not name the film-maker but said he had "a staff of dozens who enabled... and encouraged" his behaviour.

"When I turned the director down repeatedly, he sulked and punished me" and "framed (me) as the difficult one", she said.

Von Trier's award-winning 2000 musical drama Dancer, for which Bjork won a Best Actress prize at the Cannes film festival in 2000, remains the Icelandic star's only film.

Producer Peter Aalbaek Jensen, who has partnered with von Trier on many films including Dancer In The Dark, told Jyllands-Posten that he and von Trier "were the victims".

"That woman was stronger than both Lars von Trier and me and our company put together. She dictated everything," he said.

It is not the first time von Trier has been at the centre of controversy.

A leader of the Dogme 95 cinema movement that frowns on special effects, he is known for his black humour and shocking scenes of sex and violence in films like Melancholia and Breaking The Waves.

He was kicked out of the Cannes festival in 2011 for telling a news conference he sympathised "a little bit" with Adolf Hitler. He later apologised for the comment.
