Many people claim that when things get hot and heavy on the big screen, the actors simply follow choreographed moves of a script to simulate x-rated acts. However, that is not always the case, as these cinematic productions have proved.

1. The Brown Bunny (2003)

This movie was recorded using handheld 16 mm cameras in many locations throughout the US, including Ohio, Utah, California, Massachusetts, Nevada, and others. The film features Bud Clay, a skilled motorbike racer who went from New Hampshire to California for a race.

On his way, he crossed paths with many ladies who helped him have a great time. However, none seemed to satisfy him.

In the film, Chloe Sevigny gave Vincent Gallo oral sex, not because she was getting paid to do it for the film, but because they were actually dating in real life.

2. Love (2015)

Back in 2015, this French romantic drama was among the hottest films. Gaspar Noe directed the movie, and it leaves nothing to the imagination as it displays everything as it is.

The movie uses 3D to achieve this. The film centers on Murphy, a cinema school student, and his former girlfriend, Electra.

They get into a highly sexualized and emotionally charged relationship.

3. The Idiots (1998)

Lars von Trier directed this 1998 Danish comedy-drama. The cast members push every boundary while trying to make a fool out of themselves.

However, things got real pretty quickly. The film was quite a hit, and it had a pretty respectable ranking of position 76 on Empire Journal's "The 100 Best Films Of World Cinema" back in 2010.

It has also been placed among the movies you should watch before you die in the book "1001 Movies You Must See Before You Die."

4. Psykologens Dagbog (1999)

This film is unconventional, and it features plenty of adult scenes. There were powerful reactions after it went public due to the masturbation scenes.

Nevertheless, the movie's director, Jessica Nilsson, explained that these depictions are part of why the movie is so great. The movie was made as a romantic comedy for ladies.

5. Romance X (1999)

There are many steamy scenes in Romance X. The movie centers on Marie, who is a young woman living with her boyfriend, Paul.

Her boyfriend cuts her off, and she sets off on a journey that turns out to be quite empowering and fulfilling. As a result, she ends up in many relationships, including a romantic entanglement with an older man.

6. Lie With Me (2005)

This Canadian film has a lot of interesting things. The movie is based on a novel, and it tells the story of a carefree fanatic who is always thinking of getting it on regardless of the place and time.

The woman got into an affair with a younger man, although she remains dissatisfied with the emotional side of the relationship. The film stars Lauren Lee Smith and Eric Balfour, and it has been ranked among the most romantic movies.

7. Antichrist (2009)

The film features Willem Dafoe and Charlotte Gainsbourg, who are a married couple. The movie features the two doing it on many occasions, although they usually use stunt doubles for these scenes.

Some of the scenes in the film are quite graphic, and they involve self-mutilation. The film centers on a couple that goes on a getaway to their cabin in the woods with the hope of restoring their troubled marriage.

Unfortunately, things took a turn for the worse and quickly moved from bad to worse.

8. Shortbus (2006)

This American comedy-drama centers on New Yorkers who normally visit Brooklyn. The film had pretty good ratings from critics, and it had many unsimulated sexual encounters.

9. Intimacy (2001)

A failed London musician visits a lady every Wednesday as a way to release some of the tension his life puts on him. There are many scenes with hardly a word shared that are very intimate.

It turns out that this was all real, and later, Kerry Fox, who was in these steamy sessions with Mark Rylance, explained that she had no regrets about it.

10. Baise-Moi (2000)

This movie was quite controversial, thanks to its graphic nature. The movie's title could mean sex or kiss, which is why the film means "kiss me" in French.

That should be pretty clear after watching the film, which is also full of steamy intimate scenes. Basically, the story involves two young ladies that did not have the best lessons from society.

The pair then set out on a destructive tour where they break laws and try to get rid of all men.

11. Ken Park (2002)

This rousing and provocative film shows what life is like for many young people in California. One of the characters betrays his girlfriend by sleeping with his mom.

These scenes are not simulated.

The film is about Californian skateboarders who lead dysfunctional lives. The film is set in Visalia, California.

12. 9 Songs (2004)

This story involves Lisa and Matt, and it also features actual performances by major music groups such as The Dandy Warhols. However, the film also includes many sex scenes, making it the most sexually specific mainstream movie ever made.

The two leading actors are involved in several scenes in which they take part in unstimulated sex.

13. Wetlands (2013)

David Wnendt directed the German film, and there's a scene where guys had some fun with pizza. Apparently, the scene that featured spurts of semen was all real.

The movie is based on a novel by Charlotte Roche.

14. 8MM 2 (2005)

This movie centers on an aspirant who is confronted with blackmail over an encounter he had with his Hungarian fiance.

18. Sweet Sweetback's Baadasssss Song (1971)

Many studios did not want to finance this movie. So, Melvin Van decided he would do it by himself.

He took pictures independently and did all the personal stunts.

There were also unsimulated sex scenes, and Melvin ended up getting gonorrhea from an actress during the filming. Mario Van Peebles, Melvin's son, later confessed to being forced into taking part in the film by his father.

All his dad wanted was to complete the movie.

What Do You Think?

Surprised? As you can see, not all the sex you see in films is simulated.

Some of these intimate moments are actually very real.
