Not Recommended — Glass Onion: A Knives Out Mystery is not suitable for younger children. The film includes themes and content that are far too advanced for this age group. The mystery involves murder and deception, which may be confusing and frightening for little ones. Additionally, the humor is often sophisticated and may go over their heads.

Older Kids (Ages 8-12)

However, parents should be aware of specific scenes that contain strong language, sexual references, and moderate violence.

Content Analysis

Violence & Action

Violence Level: Moderate. Glass Onion includes some violent scenes, although they are handled in a less graphic manner than traditional thrillers. Specific scenes to note include:

• Shooting Scene: A character is shot in a non-detailed manner, followed by a brief sight of blood. While not excessively graphic, it may still be unsettling for sensitive viewers. Intensity: Moderate.
• Choking Scene: Another character chokes and collapses onto a glass table after ingesting a toxic substance. This moment is intense and may evoke a strong reaction. Intensity: Moderate-High.
• Dead Bodies: There are images of dead bodies throughout the film, but they are not shown in a gruesome manner. Intensity: Mild-Moderate.
• Threatening Situations: Some characters make violent threats towards others, although these moments are often played for comedic effect. Intensity: Mild.

Language & Profanity

The film contains infrequent strong language, including the use of the word ‘f**k’, along with milder terms such as ‘bitch’, ‘shit’, ‘ass’, and ‘hell’. While the language is not pervasive, its presence may be concerning for younger viewers.

Scary or Intense Scenes

The film’s lighthearted tone is occasionally disrupted by moments of tension, particularly during the mystery’s climax. However, the comedic elements often diffuse the intensity. Some specific callouts include:

• Death Reveals: The reveal of the character’s death is sudden and may be shocking, but the overall tone remains comedic.
• Argument Scenes: Characters argue heatedly, which can create a sense of unease, but again, this is largely offset by humorous dialogue.

Sexual Content

Sexual content is present but is portrayed in a humorous light. Key moments include:

• Moderate sexual references, including jokes about “boner pills” and “consensual cuckolding”.
• Brief sight of a sex toy, which may be inappropriate for younger viewers.
• Suggestive dialogue that may go over the heads of younger audiences but is clear enough for older teens.

Drugs & Alcohol

There are occasional depictions of drug use, such as:

• Pre-rolled joints and a cannabis plant shown in one character’s room.
• References to smoking joints during social gatherings.

These elements are not glorified and are presented in a context that may not be suitable for children.

Positive Messages & Role Models

While the film is a murder mystery, it also touches on themes of friendship, deception, and the consequences of wealth. The characters represent a range of personalities, providing various perspectives on morality. However, the lack of clear role models may be a concern for parents looking for positive figures for their children to emulate.

Parent Discussion Guide

After watching Glass Onion, consider discussing these questions with your teen:

1. Trust and Deception: The film revolves around who can be trusted. What elements of trust do you think are crucial in friendships, and how do the characters in the film demonstrate or undermine trust?
2. Wealth and Consequences: The movie explores themes of wealth and privilege. How do you think wealth influences the characters’ decisions and relationships? Can money change a person’s character?
3. Humor in Dark Situations: The film uses humor to address serious themes. How do you feel about this approach? Do you think humor can help us deal with tough subjects?
4. Character Analysis: Discuss your favorite character in the film. What qualities did they show? Were their actions justified given the circumstances?
