The film represents Evelyn, a middle class white teenage girl, as the possessed protagonist in a supernatural thriller. This challenges conventions by having a female in this role rather than a protected male. Evelyn's appearance and body language are inspired by Carrie White from the film Carrie, showing vulnerability through closed posture. Fast-paced editing, inspired by other supernatural thrillers popular with 15-24 year olds, maintains attention and pace throughout the opening sequence against more traditional slow openings. Sound uses layers of diegetic voices and non-diegetic effects like church bells to create an eerie tone similar to Arlington Road. Close-up camera work and character movement keep the sequence mysterious and the audience anticipating what's next.
