The BBFC

 The British Board Of Film Classification is an organisation that is in charge of all of the rules and regulations that studios have to stay within, to have certain age ratings on their films in the UK. A film can't be released into the cinema or onto DVD without having an age rating from the BBFC.

The BBFC have to consider many different things when rating a film for example, Violence, Sex/nudity, Self Harm, Criminal activity, Drugs Alcohol Cigarettes, Strobe lighting and a couple more. However these different reasons are measured in context, so if there are guns used in a war film then it would be a higher rating, but if there were guns used in a cartoon it would be a lot lower rating due to the fact that cartoons are noticeably fake.

'U' rating:

Suitable for Ages 4 and up recommended. Very mild violence, dangerous behaviour, language, nudity, threat, sex if any at all.

'PG' rating:

Suitable for ages 8 and over recommended but children can watch unaccompanied by and adult, if allowed by the parent. mild violence, dangerous behaviour, language, nudity, threat, sex and innuendos allowed but within reason. Nothing scary prolonged to scare the children.

'12A/12' rating:

For 12A children under the age of 12 can watch but only accompanied by an adult with their consent. For a 12 no one under the age of 12 is allowed to buy or rent the film and not recommend to watch. Mild violence, dangerous behaviour, language, nudity, threat, sex and innuendos allowed but within reason. Nothing scary prolonged to scare children.

'15' rating:

For no one below the age of 15 to watch, buy or rent. strong violence, dangerous behaviour, language, nudity, threat, sex and innuendos allowed but nothing massively prolonged and too strong.

'18' rating:

For people above the age of 18 (adults). Anything is allowed as long it is not a breach of the law.

'R18' rating:

For people above the age of 18 (adults). Anything is allowed as long it is not a breach of the law, but can only be sold with a specific license.

For our opening sequence I would give it a rating of Age 15 and above. This is due the Violence involved being prolonged and gruesome, even tho it won't involve any sex references, within the opening sequence, the fact it is prolonged violence, when it could be hidden, increases the rating. Also the fact she is being chased by an unknown on a loud motorcycle would make it too scary for it to be rated a 12.
