This treatise examines the intersections, contrasts, and cultural resonances between American Psycho (principally Bret Easton Ellis’s 1991 novel and Mary Harron’s 2000 film adaptation) and the emergent category I’ll call “vegan movies” — films that explicitly foreground veganism, animal ethics, plant-based diets, or use veganism as a key narrative or thematic element. I trace thematic parallels and tensions, explore representational choices, consider moral aesthetics and spectacle, and suggest lines for further research and creative practice. The aim is comparative and interpretive: to show what insights about consumption, identity, violence, and hypocrisy arise when these texts are read together.
