Parents need to know that this movie is very close to an NC-17. It has exceptionally explicit sexual references and situations and extremely strong language, including racist and homophobic comments. There's nudity, including scenes in a strip bar. The movie also has very grisly images including bloody body parts and blood-drenched rooms. Characters are killed. The movie includes a lot of smoking and drinking, including drunkenness.
The version of the film IN THE CUT that I saw was the subtitled UNCUT UNRATED DVD EDITION which is basically an NC-17 rated version of the film. There is extremely explicit sexual interactions with movements and sounds. The book is not nearly as rude and even though I love the story I couldn't believe this.
