The document discusses the costume design and props used for the main characters in a film. James, the stalker, wears a blue jacket and glasses to appear nerdy and not like a typical killer. Kelly and Jessica wear typical teenage clothes to appear harmless. Nathan wears various colored t-shirts to match Kelly's vibrancy but wears black when angry. Key props include the iPhone, which displays obsessive texts from the stalker, and photos of Kelly that show the extent of the stalker's obsession.
