This document provides an overview of film genres and subgenres, including their purposes and conventions. It begins by defining genre as a category or kind used to classify films. Subgenres are then introduced as genres that combine elements of multiple genres, such as action thrillers. The document lists several basic film genres and encourages thinking about what makes a film fit a certain genre. It emphasizes that genres and their conventions evolve over time. Students are assigned a partner project to research a subgenre, identify conventions based on several example films, and present their findings in a PowerPoint.
