Film Classifications Explained: A Guide to Age Ratings

You may be familiar with seeing a large 'PG' or 'R' flash on your screen before a movie begins. Most have a general idea of what these age ratings mean and how they indicate the appropriateness of a film's content. However, they may not understand the process or the criteria for how movies are classified. Today, most movies are released on multiple online platforms and movie theaters simultaneously. As a result, worldwide audiences have more access to internationally produced content than ever before, so understanding age ratings for films is more important than ever. This post discusses US film ratings are determined, explains the different movie classifications, and how they are essential in international distribution.

Why Are There Movie Ratings?

In the United States, the MPAA (Motion Picture Association of America), an industry, non-governmental organization, created the current rating system in 1968. It is designed to educate and inform parents to make appropriate movie-viewing choices for their children and families and provide a unified classification of film titles. This system was created to prevent the film industry from simply denying a film's distribution based on a set of moral standards on which not everyone may agree.

Many countries, including some of the world's largest movie markets, utilize governmental censors or regulators to provide age ratings. Unlike the US, where the banning of films is extremely rare, movies and TV shows are routinely censored or banned in countries like China, Russia, Malaysia, and several Middle Eastern countries.

What are the Ratings Used in Film Classifications?

Content is classified for audience suitability based on several factors. Most countries have a unique set of ratings, possibly none, but many classification systems look at similar influencing factors to determine an age rating. Elements such as language, sex, nudity, drug use, violence, horror, discrimination, and other dangerous behavior are common citations for different age ratings.

The same five movie age ratings in the United States have been in place since 1990 when the NC-17 rating was introduced to replace the former X-rating. We detail the individual ratings below.

General Audiences (G): This rating is generally viewed as accessible for all ages. Ideally, this rating is given to a movie deemed appropriate enough for children to watch without any permission or guidance from parents or adult guardians.

Parental Guidance Suggested (PG): With PG ratings, a parent may or may not need to make a judgment call if the material is suitable for their children. Typically, PG films may include animated violence or language that may not be suitable for younger children. In this case, a parent may accompany a child to a viewing at a movie theater.

Parents Strongly Cautioned (PG-13): This rating may be newer than you realized, having been created in 1984 to alert parents of slightly intense content. This rating gets the name PG-13 as it suggests the movie may not be appropriate for pre-teenage children. Themes such as stronger language and more graphic violence or horror may be prevalent in films with PG-13 ratings. Parents should be cautious and accompany children under 13 to see a movie with this rating.

Restricted (R): A movie with an R rating will certainly contain adult content. This means parents would be wise to learn more about the film before deciding whether to allow a child to accompany them to watch this movie. Anyone under 17 needs a parent or adult guardian present to be admitted to a film screening.

No One 17 and Under Admitted (NC-17): NC-17 ratings flag parents the movie in question is clearly for adult eyes only, and children will not be permitted to any movie theater showings, regardless of granted adult permission or not. Whereas other movie ratings allow parents to choose what their children get to see, the NC-17 rating was proposed by the National Association of Theater Owners (NATO) to prevent legal action from happening.

It is not a requirement for films or TV shows to be submitted for a rating in the US—unless they seek commercial release. A movie is labeled as unrated (UR) or not rated (NR) if no rating is sought or available. This is not common. While some filmmakers may elect not to have their films rated, they significantly reduce the work's commercial and financial opportunities. Many platforms and theaters refuse to exhibit unrated, or NC-17 films (mostly because there is little market for them), and many online platform search algorithms automatically exclude such content in their results.

How Are U.S. Movie Ratings Determined?

The MPAA ratings board consists of three MPAA staff "senior raters" and no more than ten anonymous parental members, all with kids between the ages of five and 15. Members are limited to seven year terms, or until their youngest child turns 21, whichever comes first. These board members make up a group known as the Classification and Rating Administration (CARA). Members view submitted films, discuss their thoughts, and vote on a final rating. The findings are then reported to a producer of the film. The determined rating can always be disputed by the filmmaker or re-submitted once appropriate edits are made to adjust the movie's rating before release. An appeals board can overturn rating decisions by a majority vote.

Ratings are established for the life of the film. Only in cases where revisions are made, additional content added (e.g., a "Director's Cut"), country regulatory edits are required, or the producer appeals will the MPAA reconsider re-rating a film.

For example, the MPAA originally wanted to rate Steven Spielberg's 1984 film "Indiana Jones and the Temple of Doom" with an "R" rating due to the graphic depiction of a beating heart torn from a man's chest and child slavery. Spielberg argued an "R" was too restrictive while acknowledging the film's PG rating caused difficulty for many parents given the content. He called on the MPAA to create a new rating between PG and R. The MPAA obliged, creating the PG-13 rating.

The Global Rules of Content Are Changing

Across the past eight issues of Spherex’s weekly World M&E News newsletter, one theme has become undeniable: regulation, censorship, and compliance are rewriting the rules of global media. From AI policy to platform accountability, from creative freedom to cultural oversight, content creation is now inseparable from compliance.

1. Platforms Tighten Control Through Age and Safety Laws

U.S. states such as Wyoming and South Dakota have enacted age-verification laws that mirror strict internet safety rules already seen in the U.K., signaling a broader legislative trend toward restricting access to mature material.

At the same time, Saudi Arabia’s audiovisual regulator ordered Roblox to suspend chat functions and hire Arabic moderators to protect minors—an example of government-imposed moderation replacing voluntary compliance.

Elsewhere, Instagram’s PG-13 policy update illustrates how platforms are preemptively adapting before new government rules arrive.

2. Censorship Expands — Even as Its Methods Evolve

Censorship remains pervasive but increasingly localized. India’s Central Board of Film Certification demanded one minute, 55 seconds of cuts from They Call Him OG, removing what they considered violent imagery and nudity.

In China, the horror film Together was digitally altered so that a gay couple became straight using AI. Responding to Malaysia’s stricter limits on sexual or suggestive content, censors excised a “swimming pool” scene from Chainsaw Man – The Movie.

Israel’s culture minister threatened to pull funding from the Ophir national film awards after a Palestinian-themed film about a 12-year-old boy won best picture.

3. AI and Content Creation: Between Innovation and Oversight

AI remains both catalyst and controversy. Netflix announced new internal policies limiting how AI can be used in production to protect creative rights and data ownership.

OpenAI’s decision to allow adult content on ChatGPT under “freedom of expression” principles sparked industry debate about whether platforms or creators set the moral boundaries of AI. OpenAI’s CEO Sam Altman emphasized in a statement, the company is “not the moral police.”

Meanwhile, California passed the Digital Likeness Protection Act to combat unauthorized use of celebrity images in AI-generated ads.

4. Governments Target Global Platforms

The Indonesian government is advancing a sweeping plan to filter content on Netflix, YouTube, Disney+ Hotstar, and others using audience-specific content suitability metrics.

At the same time, the U.K. and EU are reexamining long-standing broadcast rules, with Sweden’s telecom authority proposing the deregulation of domestic broadcasting to encourage competition.

These diverging approaches—tightening in one market, loosening in another—underscore the growing fragmentation of global compliance standards.

5. Compliance as Competitive Advantage

The real shift is strategic: companies now see compliance as value creation, not red tape. As Spherex has argued in recent Substack articles, The Hidden Costs of Non-Compliance in Video Content Production and Why Content Differentiation Matters More Than Ever, studios and creators who anticipate regulatory complexity and make necessary edits on their terms while remaining true to their stories can reach more markets and larger audiences with fewer risks.

In other words, understanding compliance early has become the difference between limited release and global scale.

Conclusion

From new age-verification laws to AI disclosure acts and streaming filters, regulation now defines the boundaries of creativity. The next evolution of media will belong to those who can move fastest within those boundaries—leveraging compliance not as constraint but as clarity.

YouTube Thumbnails Can Get You in Trouble

Here’s Why Creators Should Pay Attention

When we talk about content compliance on YouTube, most people think of the video content itself — what’s said, what’s shown, and how it’s edited. But there’s another part of the video that carries serious consequences if it violates YouTube policy: the thumbnail.

Thumbnails aren’t just visual hooks — they’re promos and they’re subject to the same content policies as videos. According to YouTube’s official guidelines, thumbnails that contain nudity, sexual content, violent imagery, misleading visuals, or vulgar language can be removed, age-restricted, or lead to a strike on your channel. Repeat offenses can even result in demonetization or channel termination. That’s a steep price to pay for what some may think of as a simple promotional image.

The Hidden Risk in a Single Frame

The challenge? The thumbnail is often selected from the video itself — either manually or auto-generated from a frame. Creators under tight deadlines or managing high-volume channels may not take the time to double-check every frame. They may let the platform choose it automatically. This is where things get risky.

A few seconds of unblurred nudity, a fleeting violent scene, or a misleading expression of shock might seem harmless in motion. But when captured as a still image, those same moments can trigger YouTube’s moderation systems — or worse, violate the platform’s Community Guidelines.

Let’s say your video includes a horror scene with simulated gore. It might pass YouTube’s rules with an age restriction. But if the thumbnail zooms in on a blood-splattered face, that thumbnail could be removed, and your channel could be penalized. Even thumbnails that are simply “too suggestive” or “misleading” can get flagged.

Misleading Thumbnails: Not Just Clickbait — a Violation

Another common mistake is using a thumbnail that implies something the video doesn’t deliver — for example, suggesting nudity, shocking violence, or sexually explicit content that never appears in the video. These aren’t just bad for audience trust; they’re a clear violation of YouTube’s thumbnail policy.

Even if your content is compliant, the wrong thumbnail can cause very real problems.

The Reality for Content Creators

It’s essential to recognize that YouTube’s thumbnail policy doesn’t exist in isolation. It intersects with other rules around child safety, nudity, vulgar language, violence, and more. A thumbnail with vulgar text, even if the video is educational or satirical, may still result in age restrictions or removal. A still frame with a suggestive pose, even if brief and unintended in the video itself, can be enough to get flagged.

And for creators monetizing their work, especially across multiple markets, the risk goes beyond visibility. A flagged thumbnail can reduce ad eligibility, limit reach, or cut off monetization entirely. Worse, a pattern of violations can threaten a channel’s long-term viability.

What’s a Creator to Do?

First, you need to know how to spot the problem and then know what to do about it. Second, you need to know if the changes you make might affect its acceptance in other markets or countries. Only then can you manually scrub through your video looking for risky frames. You can review policies and try to stay up to date on the nuances of what YouTube considers “gratifying” versus “educational” or “documentary.” But doing this at scale — especially for a growing content library — is overwhelming.  

That’s where a tool like SpherexAI can help.

A Smarter Way to Stay Compliant

SpherexAI uses frame-level and scene-level analysis to flag potential compliance issues — not just in your video, but in any frame that could be selected as a thumbnail. Using its patented knowledge graph, which includes every published regulatory and platform rule, it will prepare detailed and accurate edit decision lists that tell you not only what the problem is, but also for each of your target audiences. Whether you're publishing to a single audience or distributing globally, SpherexAI checks your content against YouTube’s policies and localized cultural standards.

For creators trying to grow their brand, monetize their work, and stay in good standing with platforms, that kind of precision can mean the difference between success and a takedown notice.
