coordinated their efforts. In this way, we never had to play to a facility's weakness." Fincher visualized the Narrator's perspective through a "mind's eye" view and structured a myopic framework for the film audiences. Fincher also used previsualized footage of challenging main-unit and visual effects shots as a problem-solving tool to avoid making mistakes during the actual filming. The film's title sequence is a 90-second visual effects composition that depicts the inside of the Narrator's brain at a microscopic level; the camera pulls back to the outside, starting at his fear center and following the thought processes initiated by his fear impulse. The sequence, designed in part by Fincher, was budgeted separately from the rest of the film at first, but the sequence was awarded by the studio in January 1999. Fincher hired Digital Domain and its visual effects supervisor Kevin Mack, who won an Academy Award for Visual Effects for the 1998 film What Dreams May Come, for the sequence. The company mapped the computer-generated brain using an L-system, and the design was detailed using renderings by medical illustrator Katherine Jones. The pullback sequence from within the brain to the outside of the skull included neurons, action potentials, and a hair follicle. Haug explained the artistic license that Fincher took with the shot, "While he wanted to keep the brain passage looking like electron microscope photography, that look had to be coupled with the feel of a night dive—wet, scary, and with a low depth of field." The shallow depth of field was accomplished with the ray tracing process. Other visual effects include an early scene in which the camera flashes past city streets to survey Project Mayhem's destructive equipment lying in underground parking lots; the sequence was a three-dimensional composition of nearly 100 photographs of Los Angeles and Century City by photographer Michael Douglas Middleton. The final scene of the demolition of the credit card office buildings was designed by Richard Baily of Image Savant; Baily worked on the scene for over fourteen months. Midway through the film, Tyler Durden points out the cue mark—nicknamed "cigarette burn" in the film—to the audience. The scene represents a turning point that foreshadows the coming rupture and inversion of the "fairly subjective reality" that existed earlier in the film. Fincher explained: "Suddenly it's as though the projectionist missed the changeover, the viewers have to start looking at the movie in a
