The document analyzes the opening titles of three thriller films to understand common codes and conventions. Possession uses wispy white titles over a night skyline to set a mysterious tone. The Cheap Detective has traditional white titles on a dark, smoky background, establishing a secretive mood. Panic Room features large angled titles reflecting off skyscrapers as it pans through New York City, implying distortion and uncertainty. Overall, the analysis found that thriller titles commonly use white text on a dark background, establish setting, are fast-paced, and aim to mysteriously set the scene and mood for the film.
