Choosing a Certificate for 'Se7en Devils' - 15

After my research on different types of age classifications given by the BBFC, particularly those given to horror films, I have decided to give my film a 15 rating.

The reason I have chosen a 15 certificate is because my film will contain limited amounts of graphic violence and gore, but will instead focus on sustained threat and menace, making it more of a psychological horror. It will also contain frequent uses of strong language and overall dark themes. However, I still want to reach as wide an audience as possible, therefore a 15 certificate will open 'Se7en Devils' up to a broader range of viewers.
