by the crow, and transforms into a creature similar to the one in the warehouse. This new monster kills Norman, but Claus and Roger barely escape in a humvee, using a machine gun attached to the vehicle to destroy it. As the two men drive out of the city, Claus asks about the virus. Roger explains how it fuses with genes, enabling Dr. Cameron to regenerate her body in other life forms, and thus making her nearly immortal. Roger then impales Claus with tentacles, pinning him to the seat. At this point, Roger is revealed to have two faces, the second one being Dr. Cameron's. The researcher explains that she was watching them in the body of the dog while they were in the warehouse, and that she realized that Umbrella was pursuing her research data. Dr. Cameron tells Claus that he and his team turned out to be perfect guinea pigs for the virus she had created, and that she will continue her experiments, trying to return herself to a human form. Using tentacles, she rips Claus' face apart. Production and release The concept for Biohazard 4D-Executer was originally conceived by anime director Yasuhiro Imagawa, who proposed his idea of the film to Capcom, the game company responsible for the Resident Evil series. The project was announced to the public in late October 1999, under the tentative title Biohazard 4D-Horror. In the early stages of development, Imagawa was responsible for the planning and the screenplay, and he collaborated on the film with director of photography Shinji Higuchi. The final script was written by Daisuke Okamoto, under the supervision of Capcom's screenwriting subsidiary Flagship. Former Capcom Production Studio 2 game designer and producer Keiji Inafune and Flagship co-founder Noboru Sugimura served as executive supervisors. Inafune referred to the story as a "gaiden" – or side-story – for fans of the Resident Evil series. The film marked director Koichi Ohata's first experience with computer-generated imagery (CGI), after his previous work on original video animations such as MD Geist, Cybernetics Guardian and Genocyber. The CGI rendering was handled by the company Visual Science Laboratory, with the creature designs provided by 3D artist Gouta Nanami. Due to the strong graphic violence depicted, shorter versions of the 20-minute film were created, from which certain scenes were cut. Biohazard 4D-Executer is presented in 5.1 surround sound, and features music composed and orchestrated by Yoshihiro Ike.
