The scientific community，an integral part of Sci-Fi films featuring disaster narratives，has been constructed as multiple images. As a key element in science communication，the images of the scientific community in films exert a tremendous impact on how accurately scientists，the public and mass media interpret its connotations. This study explores the image construction of the scientific community in Sci-Fi films from the perspective of comparative narratology. It starts with a survey of Western film history，focusing on the shifting roles of the scientific community，including a loosely-bound organization in name only，an old school hindering the advancement of science and technology，and an almighty savior. It then analyzes The Wandering Earth II，a great representative of contemporary Chinese Sci-Fi films，unveiling its imprints of Oriental culture as well as Chinese features. Based on this comparative study，it further points out that the images of the scientific community in films can boost the communication of scientific spirit and scientific ethics，strengthen the confidence of the human race as the determinant of historical progression，and provide valuable materials for the reflection upon and reconstruction of this community in the future.
