There are a few crude references through out the movie

There is an implied homosexual relationship

Two men kiss on the lips

In one major scene, a man is strangled to death, in very visceral, slow detail. This was done in such a realistic way, with no "black humor" overtones.

A woman has a heart attack.

A man is beaten with a mallet.

A man is shot with a crossbow.

"Jesus" and "Jesus Christ" used as exclamations.

Some, generally mild. "Bloody", "bugger". Occasional homophobic slurs inc. "faggot".

A number of intense sequences, usually lacking in graphic violence but still potentially disturbing
