A lot of sex. Some scenes, but not all, are done using CGI and camera tricks. Example: You don't actually see a penis go into a girl's mouth when she gives oral sex. You just see the top part of her head going up and down.

The Australian version is heavily modified so no vaginal shots are seen. However throughout the movie, there is a constant flow of close-ups of men's penises ejaculating, all including erect and flaccid.

Several instances of erect penises displayed in full view. In one scene, the main character performs unsimulated oral sex on a man.

The Director's Cut version is extremely explicit, with many closeup shots of vaginal and anal penetration.

Violence isn't frequent, but when it happens it's strong and bloody.

Joe goes to a young man, only referred to as K, who performs sadomasochistic acts on women who desire such. He ties her up and whips her buttocks many times until the skin is covered with welts and blood.

Many F-words, 5 C-words, many other anatomical and scatological profanities.

Alcohol is consumed in a couple of scenes.

(Deleted. Personal opinions about ratings are not appropriate for the Parents Guide.)

The second volume is extremely disturbing and violent, and the sex scenes/nudity are intense. These sequences unexpectedly start and end abruptly.

The scenes with K are quite graphic, and can be hard to watch.
