There is a dream sequence where a woman's bare breasts are visible. She moans loudly and tells the man she's having sex with that he's big. The scene is played for laughs.

A woman is drilled through the head with a sphere. A young boy stabs a thief, lands a hatchet in a woman's head and shoots a man.

Yellow goo oozes out of a demon nurse and one of the main characters at the end.

Lots of shooting, stabbing and violence with nunchucks.

A zombie is thrown over a balcony. Another one's head twists until it flies off.

The Tall Man opens the head of a preserved body and takes the brain out.

As I recall there is one use of the word "fuck". Lots of use of the words "shit" and "goddam".

None that I recall.

The violence in Phantasm 3 is very bloody

The dwarves and zombies may also be scary to some.
