During regression hypnosis, a patient says that his 17-year-old friend's girlfriend is pregnant.

Prot tells Mark that unlike for humans, the reproductive process on K-PAX is quite unpleasant. He then goes on to say that it's like "having your nuts in a vice, except we feel it all over." He then adds, "To make matters worse, the sensation is associated with something like your nausea accompanied by a very bad smell. The moment of climax is like being kicked in the stomach and falling into a pool of mot droppings." When Mark then asks how they reproduce if it's such a terrible experience, Prot replies, "As carefully as possible."

A husband and wife wake up in the middle of the night in their bed. The man is not wearing a shirt.

We see a flashback to a man returning home to the above scene (with some blood briefly seen on the wife and on a wall), grabbing the assailant and hearing that he snapped his neck "like a twig." We then see some brief struggling (in a distorted view) and then see a body hit the floor.

We hear that Howie tried to kill Ernie by strangling him (but we don't see any of that and hear that he did so as another of Prot's tasks to help cure both him and Ernie).

1 use of the word "fucking".

one single use of "fucking" used by K-pax very brief though.

11 uses of "shit".

"Damn" is used twice.

Phrases: "Are you f*cking deaf?" "Bullsh*t," "I'm sick and tired of this sh*t," "Don't give me this beam of light sh*t," "You stink," "Nuts" (testicles), "What the hell is going on here?" "Where the hell have you been?" "Cut the crap" and "Bitch."

About 11 uses of "shit". One time a character is heard saying, "Oh shit, oh shit".

Other milder profanities, such as ass, crap, damn, hell, and bitch. and one use of "goddamn".

Some civilized drinking/smoking. Protagonists shown drinking a small amount of hard liquor.

There are characters in the movie who have wine with their dinner and have beer at a backyard bbq. Nothing heavy is shown, and there are no intoxicated people.

Some emotionally intense scenes.

The story takes place in a mental institute and features several mental patients.

Prot has a mildly violent and traumatic breakdown, which is triggered by a backyard sprinkler coming on (we learn later in the movie why this is), he is tackled and restrained by 2 large men, and a woman comes running up with a hypodermic needle, supposedly containing a tranquilizer, to calm him. However, he snaps out of it and the needle is not necessary.
