Palahniuk's novel also contained homoerotic overtones, which Fincher included in the film to make audiences uncomfortable and accentuate the surprise of the twists. The bathroom scene where Tyler Durden bathes next to the Narrator is an example of the overtones; the line, "I'm wondering if another woman is really the answer we need," was meant to suggest personal responsibility rather than homosexuality. Another example is the scene at the beginning of the film in which Tyler Durden puts a gun barrel down the Narrator's mouth. The Narrator finds redemption at the end of the film by rejecting Tyler Durden's dialectic, a path that diverged from the novel's ending in which the Narrator is placed in a mental institution. Norton drew parallels between redemption in the film and redemption in The Graduate, indicating that the protagonists of both films find a middle ground between two divisions of self. Fincher considered the novel too infatuated with Tyler Durden and changed the ending to move away from him: "I wanted people to love Tyler, but I also wanted them to be OK with his vanquishing." Filming Studio executives Mechanic and Ziskin planned an initial budget of US$23 million to finance the film, but by the start of production, the budget was increased to $50 million. Half was paid by New Regency, but during filming, the projected budget escalated to US$67 million. New Regency's head and Fight Club executive producer Arnon Milchan petitioned Fincher to reduce costs by at least US$5 million. Fincher refused, so Milchan threatened Mechanic that New Regency would withdraw financing. Mechanic sought to restore Milchan's support by sending him tapes of dailies from Fight Club. After seeing three weeks of filming, Milchan reinstated New Regency's financial backing. The final production budget was $63–65 million. The fight scenes were heavily choreographed, but the actors were required to "go full out" to capture realistic effects such as having the wind knocked out of them. Makeup artist Julie Pearce, who had worked for Fincher on the 1997 film The Game, studied mixed martial arts and pay-per-view boxing to portray the fighters accurately. She designed an extra's ear to have cartilage missing, inspired by the boxing match in which Mike Tyson bit off part of Evander Holyfield's ear. Makeup artists devised two methods to create sweat on cue: spraying mineral water over a coat of Vaseline, and using the unadulterated water for "wet sweat".
