A nude boy is seen in a bathtub (visible from the chest up).

We very briefly see a man's penis and butt as he gets up while in the nude.

A man has sex on top of a woman (no nudity seen).

Lots of nightmarish imagery including:

A bathtub filling up with blood and a boy rising from the bloody water.

A boy stabbing another boy in the chest.

A man has spikes driven into his head. We see drops of blood falling down his face.

A man attacks another man and throws him down to the floor.

A head is unearthed in a flowerpot.

'Hell' and 'dammit' are the worst profanities said.

Some smoking and drinking.

Most of the movie has a very creepy atmosphere. Also some viewers could find the creature in the jar frightening.
