The two films, The Day it Ended and Murder by Numbers, are similar in that the main characters are popular teenagers from middle-class backgrounds. However, they differ in their camerawork, mise-en-scene, and editing. Specifically, the camerawork establishes the school setting, the mise-en-scene shows the characters' differing mental states, and the editing uses different pacing and music to elicit different emotions from viewers. These similarities and differences provide insights into the social groups portrayed in each film.
