In contemporary society, film, as a significant form of cultural expression, bears profound ideological connotations and cultural significance. Religious films, as a distinct genre, serve as crucial avenues for humanity to explore and contemplate religious beliefs, moral concepts, and the essence of existence. Plato’s philosophy, as a significant pillar of Western thought, exerted profound influence on the conception and depiction of religious films. This thesis aims to examine Plato’s philosophical impact on religious cinema, elucidating its significance and value via comprehensive analysis of his ideas and their manifestation in religious films. Platonic ideas transcend the realm of emotions, inciting moral conflicts and dilemmas in religious films, thereby probing the dynamics between good and evil, justice and injustice. Plato’s political concepts offer profound sociopolitical reflections within religious films, stimulating discourse on matters like authority, governance, and liberty. Additionally, it catalyzed inquiries into aesthetics and emotions. Plato’s appreciation and pursuit of beauty resonate extensively in religious films, guiding viewers into a transcendent aesthetic realm through depictions of beauty and emotion. This holds immense theoretical and practical significance in deepening individuals’ comprehension of Plato’s philosophy, fostering cultural exchange and discourse, and augmenting the artistic merit and societal impact of religious films.
