The document discusses how the opening of a film attracted its audience through certain elements. It included a cut between the protagonist and shots on a wall to set the genre and atmosphere. Dark music enhanced the mystery. It also compares the film opening to Se7en, noting they both use non-diegetic soundtracks to set a thriller/horror tone. Close-ups in Se7en and the document's film aimed to create intimacy and unease. The unique selling point is said to be the plot, which is loosely based on real serial killer H.H. Holmes and set in a modern context, intriguing history fans with its dark and twisted mood stemming from real events.
