Two characters have a sensual moment in bed at the beginning.

Woman shown wearing a bra multiple times.

A man peeps on a woman as she disrobes, it's implied that he is masturbating, although it's not explicitly shown other than him shaking.

A woman is shown in a lengthy scene nude but no explicit nudity is shown.

A woman is graphically stabbed to death in the shower. Quite bloody.

A decomposed corpse is shown. Very disturbing.

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.
