A couple has sex. We see the guy's butt. In fact, we see several men's butts during the course of the film.

In one scene, a man runs around nude and you see his genitals, but they are somewhat obscured by shadows. His butt is clearly visible.

The only female nudity is full-frontal from a corpse, but at a hard to see angle.

A few scenes of graphic violence and gore.

A trio of people are attacked by wolves in a park. One man has his hand ripped off (we see blood squirting and his hand flying through the air.) A woman has half her head ripped off (we don't really see it). The third person is disembowled (we clearly see him holding his bloody stomach but it's obscured a little by darkness).

Many corpses are seen in one scene.

A man#s throat is ripped open. We briefly see lots of blood spurting.

Another man is found dead with his neck slashed up.

Another man has his hand ripped off with bloodspurt and he is then decapitated. We see the head flying through the air with blood squirting. The head then lands on the ground and we see the mouth still moving.

A little sexual conversation including a man who says he can "f**k like a rabbit."

8 uses of "f**k"(1 sexual), a bunch of uses of "s**t", a few "ass" words(including 1 "asshole"), and a few other milder obscenities.

Cigarettes and cigars are smoked.

Coccaine is used. Drugs and alcohol are both mentioned many times.

No pop-up scares, but many very suspenseful sequences where the wolves stalk victims. There are especially spooky when we don't see them, just through their visions, quick cuts of them, just their eyes, etc.

Also in one scene, we see real film of wolves being shot and strung up. This may be especially distressing for many viewers.
