Shutter Island

The movie deals with the limits of the human mind and the sheer amount of horror and torment it can take before it snaps. It also examines the extent to which humans are capable of violence and evil. Some characters may or may not have good intentions, but the movie deliberately blurs this behavior in the service of the story. Some conversation about belief in God.

The words "f--k" is heard about a dozen times; "s--t" a few times. We also hear "dick," "prick," "cock," "screw that," "dammit," "Jesus Christ," and "Goddamn it."

Characters smoke cigarettes often, and one character smokes a pipe. The main character once had a drinking problem, but now abstains from liquor. We see him drinking whisky in flashbacks. Other characters drink in a social way. The hospital uses various sedatives and other kinds of drugs on the patients. The hero takes aspirins and there is a suggestion that they might be laced with hallucinogens or other drugs. We see the effects of these drugs through the eyes of the hero.
