'Extremely graphic' sex film premieres at Sundance

Visitors to Sundance Film Festival on Tuesday (January 21st) were treated to a surprise screening of the "extremely graphic" new movie Nymphomaniac.

The motion picture, part one of two to be released, has been cautiously anticipated due to its explicit nature and was directed by provocative filmmaker Lars von Trier.

Reviews referred to the constant nudity and explicit acts that take place during the films two-hour run.

A trailer for the movie, which stars Shia LaBeouf, was removed from YouTube in November due to breaching its rules on sex and nudity.

Sundance staff kept details of the film they would be showing a secret to almost 300 movie-goers who packed into the Egyptian Theatre in Park City, Utah.

In 2011, many thought Von Trier to be joking when he claimed to be writing a four-hour porn script that contained "a lot of very, very unpleasant sex".

The film will be released in the UK on February 22nd, with the second part premiering later in the year.
