In recent years, Korean films have become increasingly prosperous. In addition to borrowing from the classic Hollywood model, their genres have also widely incorporated local culture and values, revealing human nature. The combination of these two elements has broadened its dissemination worldwide and widely promoted Korean culture, providing some inspiration for the development of Chinese genre films. Taking the Korean disaster film “Train to Busan” as an example, this paper analyzes the general framework of cultural communication employed in South Korean films. By studying the film’s content and communication style, it becomes evident that Korean filmmakers blend local values into their narratives while referring to the Western film model. This nuanced approach not only captivates audiences but also carries cultural messages that resonate universally. At the same time, it is also compared with China’s films, which provides strategic reference for the international spread of Chinese films. By recognizing the strengths and weaknesses of both cinematic traditions, China's film industry can refine its strategies, enhancing its global reach while preserving its unique cultural identity. In essence, the success of Korean films offers valuable lessons and inspiration for the continued growth and influence of Chinese genre films in the global cinematic landscape.
