The document analyzes the openings of three horror films - Saw, The Woman in Black, and Se7en. The Saw opening uses unsteady camera work and disturbing music and imagery to create tension. The Woman in Black opening seems normal at first but uses lighting and the behavior of the children to introduce mystery. The Se7en opening shows someone researching disturbing topics and leaves the viewer questioning their identity and purpose through the use of jarring editing, music, and shots from their point of view.
