In the Realm of the Senses, 1976. Based on a true story of insatiable sexual desire, In the Realm of the Senses director Nagisa Oshima created one of the most controversial films of all time. The film also contains many gruesome scenes which were, luckily, re-enactments though all the sex was real.Slate said that “In the Realm of the Senses is a film like no other, a magical fusion of art and pornography that somehow renders debates about the distinction between those two categories boringly beside the point. Asking if this film is porn is like asking if prehistoric cave paintings showing men with erections are porn. They’re porn, they’re art, they’re elemental and beautiful; it doesn’t matter.”

Lie with Me, 2005. When audiences commented that the sex between Lauren Lee Smith and Eric Balfour looked very real, everyone on set admitted that it was.Actress Lauren Lee Smith said of the film, “It’s controversial, but it’s also something everyone will understand. It’s about a woman who is not so comfortable with the emotional side of relationships, but is so good with the physical, sexual side. Taking the role wasn’t about the ‘naked chick’ quality – it’s about showing strong, sexual women.”

Baise-moi, 2000. The French title Baise-moi is an ambiguous one.Baiser is a French verb meaning “to f*ck“, but it also means “a kiss” when used as a noun. Baise-moi would be translated as “F*ck me”.Baise-moi, in this film, can be loosely translated to Kiss Me, F*ck Me, or Rape Me, so it’s not surprising that the film is chock-full of graphic, and usually violent, unsimulated sex.

The Idiots, 1998. O Fantasma (2000)The title translates roughly to “The Ghost” or “The Phantasm.” Hmmm.Sérgio stars as a homosexual garbage collector, living alone with his dog and living a healthy sex life.
