BBFC- Rules and Regulations

In my thriller opening, me and my group have decided to make it as a 15+. We made it this because we want it to be a sort of horror as well as a thriller and we didn't think this would apply for people under the age of 15. This also still applies for a wide range of people.
I believe that the opening would have this rating due to the violence at the end of the opening. According the British Board of Film at a rating of 15, violence may be strong.
This is some of information I found on the BBFC website that tells you about what makes it a 15+ movie:

What might I see in a 15 rated film or video?
Any of the following: strong violence frequent strong language (e.g. 'f***'). portrayals of sexual activity strong verbal references to sex sexual nudity brief scenes of sexual violence or verbal references to sexual violence discriminatory language or behaviour drug taking.
   - Our opening scene isn't going to involve any of the following but later on in the movie there will be violence and strong language used throughout.

What about horror works?
At 15 there can be strong threat and horror as long as there is no sustained focus on sadistic or sexualised threat.
   - This will go for my production as it is going to have quite a lot of horror in as well as being a thriller. I think it is a good idea to incorporate the two because then it could provide for a wider range and get more people watching the thriller.

Can you see drugs in a 15 rated film or video?
At 15 drug taking may be shown but the work as a whole must not promote or encourage drug misuse (for example, through instructional detail). The misuse of easily accessible and highly dangerous substances like aerosols or solvents is unlikely to be acceptable at 15.
   - Later on in the film it might have some drug taking, but we haven't got to think about that because we are only doing the opening.

What about dangerous behaviour or things teens might copy?
We consider the risk of potential harm to impressionable teenagers. For example, dangerous behaviour such as hanging, suicide and self-harming should not dwell on detail which could be copied. Whether the depiction of easily accessible weapons is acceptable will depend on factors such as realism, context and setting.
   - We are trying to make our opening scene as realistic as possible and believe they are in the characters shoes with POV shots, however the teen will not copy our film as it is about getting kidnapped and im sure no one would like that.

How much strong language is allowed in a 15?
There could potentially be a great deal. At 15 there is no upper limit on the number of uses of strong language (e.g. ‘f***’). Occasionally there may be uses of the strongest terms (e.g. 'c***'), depending on the manner in which they are used, who is using the language, its frequency and any special contextual justification. However, continued or aggressive use will not normally be passed 15.

What about discriminatory or offensive terms?
There may be racist, homophobic or other discriminatory language, and the work could explore themes relating to this. However, at 15 the work as a whole must not endorse discriminatory language or behaviour.

How much sex and nudity is allowed at 15?
At 15 sexual activity can be portrayed, but usually without strong detail. Some sex scenes can be quite long at this category. Though nudity may be allowed in a sexual context there will usually be no strong detail. There are no constraints on nudity in a non-sexual or educational context. There can be strong references to sex and sexual behaviour, but especially strong or crude references are unlikely to be acceptable unless justified by context. Sex and sex references are treated the same irrespective of sexuality

Can there be strong violence?
Yes, at 15 violence may be strong. It should not dwell on the infliction of pain or injury, however, and the strongest gory images are unlikely to be acceptable. Strong sadistic violence is also unlikely to be acceptable.
   - In our thriller, we didn't plan to have it very gory with that much strong language, so I think ours fits in to the 15+ age range.
