1. 研究目的与意义（文献综述包含参考文献）

Literature Review Today's world has encountered more opportunities and challenges. If people encounter situations beyond their own ability to solve problems, they will have an unprecedented appeal to the savior. This is one of the reasons why hero films are constantly emerging and people are enthusiastically sought after. By watching the Chinese and American hero films, the audience's cognition of the concept of heroes and characters is also more profound. The phenomenon of differences between heroes in Chinese and foreign movies has also attracted the attention of scholars at home and abroad. American scholar Rollins (2003) mentioned that in American movies, the heroes on the screen are lonely: they stand alone, do justice, resolve the crisis one after another, and in the end there is only a lonely figure. Kissinger once said,”Americans especially appreciate the cowboy who led the team and entered the village or town alone. He may not even have a pistol because he go there not for fire" Dr. Kissinger#8217;s words express the admiration of individualism in American culture and have also been played in the film. The American superhero movie not only witnessed the development and history of the United States, but also continued the dream of the ”heroes” in the hearts of Americans. Almost all films presented the theme of ”rescue”. The heroic value of the film lies in not treating the hero with winning or losing, but the influence of a true leading figure who can also awaken the people around him and guide them to fight for freedom and democracy with independent consciousness and faith. From the above discussion, it can be seen that Western scholars recognize and support this individual heroism. Chinese scholar Qi Jin (2009) once mentioned that film is an important part of modern civilization and life. The various screen images of American hero films influence the development of world movies. The image of individual heroism strongly revealed in the film is deeply reflected the personal values of Americans. On the one hand, this kind of values advocates individuality and independence, and pursues justice and dignity; on the other hand, this pursuit implies the contradiction between individual and social order and violence. This American-style individual heroism value is fully obtained in the film. Individualism can be said to be an important part of American culture, and they advocate individual existence and development as well as free space. For heroism, it is actually caused by our worries and fears about our own living environment and humanistic philosophy. This is the deep feeling of the unknown world and the crisis of survival, so we expect those who have absolutely good quality, and always give the most favorable support and protection at the most dangerous situation. Only the perfect combination of personal ideal and heroic quality does not exist in reality, so it is necessary to fiction a perfect image to give comfort to the soul. At the same time, Hu Lixin and Fang Yongjun (2006) also proposed that the individual heroism of the Americans is the emergence of a savior, and this savior carries the hope of world peace and the surrender of disaster. This is the embodiment of the Western cultural concept, the pursuit of personal happiness and freedom, and the hope of the emergence of the Savior to save the world. This kind of individual heroism is full of savior ideals for freedom and happiness. It also contains reflections on human beings, on democracy, on society, and on American cultural values. It can be seen that Chinese scholars have a positive view of the individual heroism embodied in American hero films, and at the same time they combine Chinese unique thinking to analyze and think about them. However, due to social environment, history and other reasons, in fact, their researches on individual heroism are relatively simple. The film has shaped many American heroic figures. The thinking and exploration of individual heroism in the film should combine the views of scholars both in the Chinese and Western critics to analyze the different shapes of American films in different historical periods. Then we summarize the differences between Chinese and American heroes, and the conclusions drawn from them will also help us better understand the differences between Chinese and American cultures.

2. 研究的基本内容、问题解决措施及方案

Research purpose It can be seen that the expression of heroism in American movies and Chinese movies is totally different. The development of the film is always inseparable from history and culture. The film in each region is closely related to the history and culture in this region. The enormous influence of the film is directly projected into the cultural values of a region. In addition, the film also represents the cultural connotation of the region, in order to understand the film more completely and clearly in this region, we must start from the history and culture of this region. Film and culture are inseparable. The analysis and appreciation of films is one of the most important ways to understand the social culture of a country. People's cognition and understanding of society and life have a great influence on the interpretation and performance of the film theme. The different ”heroism”performances in the films of the two countries are actually the different historical and cultural backgrounds and value systems of the two countries. The potentially hidden culture and historical roots reflected in such a striking contrast are worth exploring. This article takes the heroism in Chinese film and American film as the research object, and analyzes the ”heroism” character image from the perspective of cross-culturalism. This will interpret the heroism in Chinese and American films, help readers to understand the differences in film culture and values between the two countries, and achieve the effect of promoting the exchange of Chinese and American film culture and enriching the theoretical system of cross-cultural communication. The research methods of this thesis are mainly literature analysis, comparative analysis, analytical induction, and review.
