Ben, the main character, is portrayed as a normal 17-year-old teenager to represent and appeal to younger audiences. He is working class, dressed casually in jeans and a jumper to show that the events of the film could happen to anyone. The second character, the unnamed murderer, is also 17 years old and dressed casually to show that anyone can be a threat and raise awareness of younger threats. The film aims to represent younger people fully and break the stereotype that horrors usually target adults.
