BBFC

Film classifications are used so the government can monitor which audience is exposed to certain themes and content in a movie. The BBFC is a non-governmental organisation which means the government has to subscribe to it. The government takes advice from the BBFC. For example they will try to prevent under 18s buying and renting DVDs without ID, if the BBFC decided on an 18 as its rating. However, due to attitudes changing classifications that were awarded in the past will be different today.

My mockumentary will be a 15 because the film as a whole would have a lot of swearing and some sexual innuendo.  However, the trailer itself only has one swear word present, and a cartoon drawing of genitals and so the trailer is going to be rated 12a.  

Universal means it's suitable for everyone. No violence, language, sex, drugs, or adult themes in this movie.

PG stands for Parental Guidance. This means kids at the age of 8 and over can watch this. It can contain some mature themes, but they are not explored in depth. There is moderate violence but it's fantasy. For example, the Christopher Reeves Superman films are all rated PG.

12A means you can watch the movie if you are under 12, but you need to be accompanied by an adult. This rating is only used for the cinema. It can contain mature themes, moderate violence, sex references, nudity, mild drug use, strong language, and very strong language was introduced in 2015.

12 means you have to be 12 or over to watch the movie. Since 2002, this rating was given only on DVDs. This rating is usually what 12As  become when they are released on DVD.

15 states that you have to be aged exactly around 15 or over to watch this movie.  These movies contain strong language, sometimes very strong language, strong violence, sometimes some sexual activities, hard drug use, sometimes bloody violence, and adult and disturbing themes like suicide or racism.

18 means you have to be aged 18 or over. These movies contain strong language, very strong language, strong bloody violence, a load of sexual activities, hard drug use, and adult themes are really explored in depth.

R18 stands for Restricted 18. These films with these certificates can be only shown in licenced sex shops if they haven't been given the 18 rating. Some films have even been not suitable for R18 even though they are still legal. These movies are certain to have hardcore pornography.
