This project explores the themes surrounding female movie characters with Borderline Personality Disorder, and how they have changed and developed over time. Using quantitative variable data collection, I will analyze the prevalence of five different themes in films about mental illness: violence, pity, faking and indulgence, comedy, and sexualization. By watching movies spanning from the 1940s to the 2010s, one in each decade (except the 60s and 2020s), I will be able to see how popular themes in these types of movies have changed in prevalence over time.
