The document analyzes common patterns and conventions found in the trailers for six supernatural/possession horror films: The Possession, Insidious 2, Sinister, The Woman In Black, The Devil Inside, and The Conjuring. Some conventions discussed include portraying normal family homes to conceal hidden evil, using innocent props that have a sinister element, including the director or actors' past work to promote the film, using religious imagery associated with possession, showing brief scary imagery to generate mystery and curiosity, and claiming the film is based on true events to increase fear.
