●Sigourney Weaver, who played Ripley in the first three films, put forward very high demands on the new film. Screenwriter Joss Weiden must bring Ripley back to life, who had died in the first episode. The script completed by Weiden is not only as thrilling as always, but also deeply explores Ripley's dual nature. This new shaping of the protagonist and her complicated relationship with the alien are enough to persuade Weaver to sign the film.
●The director of the film must not only master the special effects, plot and suspense, but also have insight into the film that breaks the tradition. French director Jean-Pierre Gennet, who has won praise for his "Black Shop Rhapsody" and "Night of Dreams Lost Soul", is the best candidate for the producer. Before meeting with the producer, Genet went to New York to meet Sigourney Weaver, and the two admiring each other quickly reached a consensus.
●In order to create bright and dark light and soft colors in the film, the director of photography Dairis Conji used Technicolor's ENR technology. This technology will not only enhance the overall contrast of the picture, but also make the deep tones richer and more saturated , Which intensifies the contrast between dark and light tones. Kang Ji believes that this color effect is especially suitable for "Alien 4" which is full of eerie and surreal suspense.
●The visual effects department of the film also aims to create a surreal artistic conception. Before the start of the film, the visual effects director Petov commissioned Silicon Graphics to produce a three-dimensional computer model for previewing certain scenes, so that he and Rene could be the same See the final effect and conduct a careful study. In the post-production stage, Petov seamlessly integrated various effects. The spectacular "Auriga" spacecraft in the film is made up of miniature models, full-scale scenery and scene paintings.
