Global film production is witnessing a surge in international cooperation and cross-border investment. However, the dynamics and structure underlying these collaborative ventures remain underexplored. This study employs social network analysis (SNA) to investigate joint investments within the cinema industry. A network of 150 countries is constructed based on 7800 links representing shared creative themes in film productions. Centrality measures identify pivotal nodes like the United States, China, and England as influential countries with strong leadership potential to steer industry growth through collaboration. Community detection further uncovers distinct thematic clusters centered around common creative endeavors such as action films or social issues. Each community reveals opportunities for targeted cooperation and investment. For instance, the Global Thrill Seekers community produces mainstream blockbusters, whereas the Cultural-Social Cinema Group tackles worldwide issues. Overall, this SNA enhances understanding of the global film network and highlights pathways to optimize data-driven decision-making regarding collaborative initiatives. The research underscores SNA's value in predicting outcomes and paving the way for strategic unity in the creative industries.
