The document discusses the character groups and individuals in the filmmakers' thriller film. They split the characters into three groups: detectives, criminals, and victims. The main detective character, DCI Walker, was inspired by characters from other films and portrayed by drama teacher Antony Clark. The other detectives, PC Hunt and PC Clark, were played by younger actors which made their roles less believable. The victim, Daisy Walker, is discussed though she does not appear. Three suspects - Darren Smith, Leeroy Jones, and Trevor Jenkins - are briefly shown on an evidence board. Locations and costumes were researched from other films to make the characters as realistic as possible for the thriller genre.
