Age restrictions

This is the age classification for films and the differences between each age restriction. 

Each film is rated for a certain age for specific reasons. Our group has decided at his point in our research to base our opening sequence between the 15-18 year old age group. there is a large difference between a '15' film and a film with an '18 certificate'.  I have done some research into the difference between both age certificate to find out why each is classed as they are. This is done as some films are seen by the media as having some unacceptable content for certain ages, so they are given a restriction so when people go to see it a the cinemas to buy it on DVD, they are required to have an ID if questioned to buy the film or the ticket to prove they are at the age where it is acceptable for hem to view he film.
 an 18 certificate .A film that is rated 18 will include some if not all of the following; frequent strong violence, a lot of strong language / frequently;  strong verbal references to sex; sexual scenes; a strong horror  blood or gore of a strong nature; drugs; discrimination for example racism or homophobic references.

  an 15 certificate. A film that is given the rating as a 15 will include some if not all of the following; fairly strong language (this will occur frequently); sexual references; brief scenes of a sexual nature; brief scenes of a violent nature; small if any references to racism; homophobia/ any other discriminating behaviour.
