History Fridge / FightClub

** Near the end of the film, when the narrator is trying to stop Tyler's plan to blow up a bunch of office buildings, he turns himself into the police detectives and insists on telling them that they're making a mistake, that he is not Tyler, etc. and the detectives (who are in on the plan) tell him "You told us you'd say all of that" because [[spoiler: Tyler anticipated that the narrator would try to stop Tyler's plans, whether or not he ever found that Tyler is just a split personality of his, so Tyler gave the detectives the heads-up.]]

** When Jack is beating himself up in his boss's room, he says that it reminds him of his first fight with Tyler, but he doesn't know why. Later, we realize that it is because [[spoiler: Tyler is a figure of the narrator's imagination, so when they were first fighting, he was beating himself up.]]

* During his argument with the narrator in the car, Tyler reveals that it was he who blew up the narrator's apartment, despite the fact that Tyler would have had to have done it before they met on the plane; that's because [[spoiler: Tyler is a split personality of the narrator's.]]

* The film is choke full of examples of FridgeBrilliance, many of them being plot points and scenes that only make sense upon a second viewing when you know the twist:

*** Those first three times Tyler appears are before the narrator has cured his insomnia, and at this point [[spoiler: the narrator is still subconsciously creating Tyler, hence the brief subliminal hallucinations]], while during the fourth time he appears, [[spoiler: it is during a brief period when his insomnia returns, and Tyler starts re-appearing during the narrator's waking hours since he is unable to be let out by taking over the narrator's body when the narrator sleeps.]]

*** Next to the narrator's doctor while the doctor is flippantly sugesting the narrator check out the testicular cancer support groups

** When the narrator gives Marla his contact information after they decide to split up the support groups, she asks him his name and a bus passes between them, then the scene cuts away before the bus moves out of the way. For the rest of the film, Marla thinks the narrator's name is Tyler Durden(even though she doesn't address him until near the end shortly before the reveal) because [[spoiler: while the bus was passing between them, he blacked out and became Tyler, introducing himself as Tyler Durden, and then woke up as his main personality sometime later.]]

** When the narrator and Tyler walk up to the convenience store, Tyler takes a gun out of the narrator's backpack and the narrator asks Tyler "Is that a gun? Please tell me that's not a gun." Despite the fact that it's ''his'' backpack.

** During the montage early in the film in which the narrator explains how his job requires him to fly around the country, he asks at one point "If you woke up in a different place, at a different time, could you wake up as a different person?" and the camera follows Tyler.

** After the car accident scene, the narrator lies in bed recovering with a large bruise on his face while Tyler talks, then Tyler gets up and leaves with a briefcase in hand. The next day when the narrator wakes up, the bruise is gone. [[YourMileageMayVary Some]] may view this as a continuity error, while [[YourMileageMayVary others]] may treat it as an indication that several days, perhaps a week or even longer, has passed, during which time [[spoiler: the narrator was not really asleep but was flying around the country as Tyler setting up the new fight club chapters.]]

** When the narrator asks Marla what she gets out of her relationship with Tyler, she dodges the question and asks "What do ''you'' get out of it?" The narrator think she is asking about ''his'' relationship with Tyler, but she is actually asking about the narrator's relationship with ''her.'' The narrator then starts to investigate the sounds of Tyler making a ruckus in the basement, but Marla says she doesn't hear anything.

** During the one scene in the film when the narrator behaves ''exactly'' like Tyler, when he's threatening his boss after the latter finds the list of fight club rules in the copy machine, he says in voiceover (presumably literally): "Tyler's words were coming out of my mouth."

** When the narrator and Tyler first start smacking car bumpers with baseball bats, Tyler hits the car first, but the alarm is triggered only after the narrator hits.

** During the scene in the car when the narrator and Tyler are arguing, the two Space Monkeys in the backseat look uneasily at each other at one point, because [[spoiler: the narrator/Tyler was driving the car and was talking to himself.]]
** Tyler gave the whole go-out-and-lose-a-fight assignment [[spoiler: so that the narrator wouldn't realize they were the same person. Tyler needed to cover up the injuries and no one would have agreed to fight the narrator after seeing Lou's brutal beating. If the narrator didn't get beat-up, he was bound to wonder why he was injured when it was Tyler who had been in the fight.]]

*** It makes the Jack's/Tyler's response, "Well then it suits you" even harsher than at first glance. He's essentially confirming that he only sees Marla as an object to be used and thrown away. No wonder she storms off afterwards.

* The film is choke full of examples of Fridge Brilliance, many of them being plot points and scenes that only make sense upon a second viewing when you know the twist:

** When the Narrator is attempting to explain himself to Marla after the reveal, she's furious with him because, as she put it, "Your whacked-out bald freaks hit me with a f**cking broom, they almost broke my arm! They were burning their fingertips off with lye, the stench was unbelievable." The lye part is easily understandable, but the broom part always kind of went over my head until one day it just dawned on me: they hit her because she was standing on the porch, just like Tyler did to them when they were trying to gain entry into the house!

** Near the end of the movie, while the narrator is flying all over the country looking for Tyler, he informs us in voiceover: "I was living in a state of perpetual de-ja-vu. Everywhere I went I felt like I'd already been there."
