In May, the movie Love caused a stir when it debuted at the Cannes Film Festival.

Before Love, two movies that became phenomena in the movie lover community were Blue is the Warmest Color and Stranger by the Lake, both of which were European works with many `hot` scenes.

`Love` is the most controversial movie this year because it tells a love story with explicit lovemaking scenes.

The film Stranger by the Lake brought French director – Alain Guiraudie – the `Outstanding Director` award, Un Certain Regard category (Another look) also at the Cannes Film Festival.

Made by radical European director Lars Von Trier, Nymphomaniac (2012) and Antichrist (2009) are both famous and infamous as the most groundbreaking works.

According to BBC writer Chris Heard, explicit sex scenes – the most extreme being real sex – are pushing cinema to new frontiers.

The trend of movies containing real sex scenes flourished with the movies The Idiots (1998), Romance (1999), Baise-moi (2000), Intimacy (2001), 9 Songs (2002).

However, Hollywood rarely exploits explicit sex scenes or real sex scenes in widely released films.

The film `Nymphomaniac` by Lars von Triers uses many real sex scenes.

Most filmmakers who use real sex scenes in their stories find the scenes important to the weight of the story as they more realistically portray emotions and story lines.

Containing scenes of “outrageous” nudity, films not for children have always divided critics and the public.

To date, Love is the most controversial film of the year as it challenges the border between art films and pornographic products.

However, some experts defend the film as a poetic story.

Critic Jonathan Romney shared: `Sexual themes are an effective means for independent directors to express their own voices.

The writer added that the sex scenes of all kinds filled in the film do not mean it is pornographic.
