In this research the influence of post-humanism and Cyborg’s character image in Alien series on science fiction film narrative and aesthetics is highlighted. Based on the post-Humanist theoretical framework, this study took the Alien films series as the research object to explore its innovation of science fiction film aesthetic paradigm. The post-humanistic thought, by deconstructing the anthropocentrism and emphasizing the blending of technology and biology, provides a unique perspective for analyzing the Cyborg elements, character modeling and visual symbols in Alien. The study found that through the reconstruction of alien creatures, the technical subjectivity of artificial intelligence and the subjectivity of female characters, the film constructed a science fiction horror aesthetic system with a philosophical depth. Its biomechanical design metaphors the alienation of scientific and technological rationality on the nature of life, and the visual hedge between the closed space scene and the claustrophobic nest reinforces the narrative tension of existential crisis. In addition, the Alien series broke through the boundaries of traditional genre films and transformed post-humanist propositions such as scientific and technological ethics and ecological symbiosis into figurative image language, thus establishing a new paradigm of “scientific and technological terror” for science fiction films. The study points out that the series is not only groundbreaking in visual symbolic systems and narrative strategies, but also expands the ideological depth of science fiction films through philosophical inquiry into the relationship between man and machine and the nature of life, thus providing a new cognitive dimension for understanding the existence of human beings in the scientific and technological era.
