With It Follows it does include sex and some nudity but in the sex scenes no explicit nudity is shown and when charatcers are nude parts are heavily shaded. There is also not a lot of blood and gore, there is some people who die but it is not very graphic.
We feel as though we should make our horror film a 15 like; It follows and The Gallows. This gives us a bigger target audience than an 18. This is crucial as 15-18 is a big part of our potential audience by being a horror. Therefore by making it an 18 we will exclude this audience which is not a good decision.
After seeing knock knock we can agree that it should be an 18 rated film, IMDb have rated it 9/10 for sex and nudity as the whole premace of the film is about sexual torture, There is also some dark refrences like pedophilia and incest. These are subjects we will not be using in our trailer, this will help us avoid the 18 rating.
Friday the 13th (2009) was given an 18 rating. On IMDb it has an 8/10 for sex and nudity. We dont intend to include this in our trailer so this will help us to cut the rating down to a 15. It does have a 9/10 for violence and gore. However it is a full length feature, so there is much more evidence of gore. In a trailer there will obviously be less blood than in the full film.
Halloween was given an 18 in 1978. When you compare it to Friday the 13th (2009), it seems remarkable that Halloween would be given an 18. It has a 5 for nudity, a 6 for violence, 3 for profanity, 4 for alcohol and drugs and an 8 for frightening scenes. This would be easily a 15 nowadays.
