The document analyzes the opening sequences of 5 thriller films - The Dark Knight Rises, Memento, The Girl with the Dragon Tattoo, Se7en, and an unnamed film - to identify conventions used in thriller openings. It finds that thriller openings often use dark colors and lighting, ominous music, vague hints about the plot or characters to build tension and mystery, and stereotypical protagonists to set expectations for the genre. They aim to prepare audiences for danger and elicit feelings of fear, suspense and uncertainty through visual and audio techniques without revealing too much of the story.
