The document analyzes the opening sequences of two films: a thriller and a crime film. For the thriller, the opening establishes a dark and ominous atmosphere through the use of silhouettes that build tension as anything could happen. It shows a woman swimming at dawn as intense music builds, with the point of view of an unseen threat. For the crime film, the opening shows the wealthy city location before a window smashes, introducing the criminal intentions. It depicts suspicious characters and oblivious people, building tension over the impending robbery. Both use music, lighting, points of view and character silhouettes to create mystery and build tension without revealing threats immediately.
