For "Advent Children", the film sequel to "Final Fantasy VII", scriptwriter Kazushige Nojima thought that the film's plot would be less entertaining without Sephiroth. His revival in the film was introduced in the early stages of development, but the official decision as to how to bring him back was not reached until later. Nomura originally planned to have him appear from the start, but as it took the staff two years to develop his design, the idea of his presence throughout the film was scrapped, and it was decided instead to have him only appear on the screen for a short time. Sephiroth was designed for the film in such a way so as to emphasize his other-worldliness, such as the fact that he never blinks or is seen breathing, and his voice remains always monotone and calm. In the film, the staff stated that his strength had considerably increased, to the point that he had "ascended to a new level of existence."
