Target Audience.
our target audience for our opening sequence would be young adults. this is because it contains elements of crime at the core of the narrative. another reason why our opening sequence would appeal to young adults between the age of 17-25 is that it has imitable behavior, this would mean that it would be unsuitable for anyone under the age of 15 to watch this particular opening sequence for example there is a point in the narrative where the main is smoking. this would be unsuitable for people under the age of 15 because they might try and imitate the actions seen on film because younger people are more susceptible to things being shown on screen.
the guidelines that the BBFC follow to make a film or production a 15 are:

Discrimination

Discriminatory language or behaviour must not be endorsed by the work as a whole. Aggressive discriminatory language or behaviour is unlikely to be acceptable unless clearly condemned.

Drugs

Any misuse of drugs must be infrequent and should not be glamorised or give instructional detail.

Horror

Moderate physical and psychological threat may be permitted, provided disturbing sequences are not frequent or sustained.

Imitable behaviour

Dangerous behaviour (for example, hanging, suicide and self-harming) should not dwell on detail which could be copied, or appear pain or harm free.  Easily accessible weapons should not be glamorised.

Language

Moderate language is allowed. The use of strong language (for example, ‘fuck’) must be infrequent.

Nudity

Nudity is allowed, but in a sexual context must be brief and discreet.

Sex

Sexual activity may be briefly and discreetly portrayed. Sex references should not go beyond what is suitable for young teenagers. Frequent crude references are unlikely to be acceptable.

Theme

Mature themes are acceptable, but their treatment must be suitable for young teenagers.
