The film contains some mild sensuality and innuendo.

Two people are seen getting dressed, it is implied that they had sex. Nothing graphic in the slightest.

A man watches a woman undress. Nothing is shown except for her in a bra

There is no explicit nudity in this movie, whereas there are a few mild ones. We see a woman in bra for an extended period of time, and we also see a lot of kisses in the movie. The shower scene avoids nudity, its blurred and nothing explicit is shown, although you see the overall shape of the persons body easily.

In one scene we see a woman in a shower turning to see a shadowy figure with a knife. She screams as the movie's dramatic theme is played, with the shadowy figure closing in with the knife still in hand. There are sound effects of the knife entering flesh, although the knife entering the flesh is not actually shown. Afterward you can see the woman possibly dead in the shower, with a bit of blood going down the shower drain.

A man is cut across the face with a knife. Some blood is on his face. He is then stabbed more offscreen.

Swearing is non-existent in this movie.

Besides a scene in which a man smokes, the drug and alcohol content of this movie is nonexistent. There is however an early scene in which drinking/alcoholism are subtly joked about between two men.

Bernard Herrmann's score can be scary and suspenseful. The stabbing violins in the iconic shower scene are startling and intense.

This film contains substantial suspense that at times transcends the plot. Although the story is engrossing, a good portion of the atmosphere arises from scenery and music, which alone may frighten younger viewers. This does not take into consideration the film's depictions of violence, that aren't graphic. The most blatant instance of violence occurs relatively early on and serves to heighten the suspense of the rest of the film.

Many scenes in the movie are frightening.
