History Fridge / FightClub

** The Narrator is seen passing a theater with ''Film/SevenYearsInTibet'' on the marquee, which first comes off as a CelebrityParadox gag, since the film also stars Creator/BradPitt. However, it also invites the idea that Tyler is played by Brad Pitt because, at least on a subconscious level, The Narrator based his mental image of Tyler on Brad.

*** This doubles as a bit of [[HilariousInHindsight Hilarious]]/HarsherInHindsight, as when you don't know the twist, you assume he's talking about the mundane travel he's doing to find Tyler and getting the same exact results each time, but once you know the twist, it becomes clear that he means more than just that.

* The pay phone that the Narrator calls Tyler on has a ''tiny'' little notice on the front of it reading, "No incoming calls allowed."
** Also, Tyler says he dialed star-69 to call back, but he has an old rotary phone without a star button.

*** Not only that, but the dialogue hints that while we're seeing things as they really are (i.e. his boss getting mad and calling for security before the Narrator beats himself up), the Narrator himself is imagining that his boss is ''actually'' beating him up, much like how he would beat himself up while imagining that he was fighting with Tyler.

*** In the narrator's office at work, when he is talking about how everything seems so far away when one has prolonged insomnia
*** Next to the narrator's doctor while the doctor is flippantly suggesting the narrator check out the testicular cancer support groups
*** At that group's first meeting the narrator attends

*** Those first three times Tyler appears are before the narrator has cured his insomnia, and at this point the narrator is still subconsciously creating Tyler, hence the brief subliminal hallucinations, while during the fourth time he appears, 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.

** One of the recipes Tyler tells the Narrator is dynamite. The insurance operator later tells the Narrator what his condo was destroyed with a home-made sample of dynamite.

** In the scene on the bus when Tyler talks about the underwear ad ("is this what a man's supposed to look like?") a guy avoids bumping into the narrator, but bumps into Tyler (of course he was just walking trough an empty space, but since the narrator is seeing Tyler there, he sees the guy bumping into Tyler).
*** Actually, it's the other way around. The man bumps into the narrator, but not into Tyler. The dude doesn't even look back and apologize, he just keeps walking, and the narrator throws him a glance. A man that doesn't care about shoving someone in the bus is not going to avoid the first person (Tyler) and then hit the second. So he obviously doesn't bump into Tyler because, for him, there's really only an empty space where Tyler is supposed to be.

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

*** And even more than that, it actually explains ''the very successful commencement ofnthe Fight Club in the first place''. Because it started with some strangers observing Tyler and Narrator fight and suddenly getting interested to the point that they themselves decided to try. Now, would an ordinary fight between two guys really elicit such a powerful reaction? Watching someone ''beating himself up and enjoying it'', on the other hand...

*** Even more telling is her reaction to the Narrator's use of "us" (meaning him and Tyler): question: "Us? What do you mean - us"?

* 'No Shirt, No Shoes' sounds like an odd rule for the club to have. The shoes part makes sense, they could hurt someone, but why no shirts? Well, there's a few reasons. The first could be to remove individuality, everyone will look the same without a shirt on, taking away their unique identities, removing brand logos or styles. But the second reason ties into [[spoiler:the twist... the reason the Narrator created 'Fight Club' was, in essence, because of Marle Singer. She kept showing up at all his clubs and meetings. So how could he keep Marla out of Fight Club? Simple: no girls allowed, or in other words, 'no shirts']]. The only one who IS allowed to wear a shirt is Bob, due to his bitch-tits. [[spoiler:Marla]] on the other hand would probably be given no such treatment.

* What the hell has that that little girl in the movie theater been through that would make her scream at the sight of a penis?

* The film is chock 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:

There’s also some FridgeHorror when you think about that little girl in the movie theater. What the hell has that child been through that would make her scream at the sight of a penis?

* According to [[https://www.cracked.com/article_26324_the-secret-fight-club-ending-everybody-missed.html this]] article, it's possible that [[spoiler:Tyler decided to martyr himself when Jack started to reassert control, something foreshadowed from the opening scene.]]

** An early hint about who Tyler actually is is referenced in a sort of FreezeFrameBonus if you have subtitles on, Tyler mentions "Strinne Green Stripe Patterns" during his and the narrators first conversation in Lou's bar, the exact type of curtain that the narrator mentioned and had during his narration about the furniture in his home.

** 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 start addressing him until near the end) because 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.

* Marla's behavior toward the Narrator looks completely insane at first: why do she follows a guy who obviously hates her, like crap, ''and'' despite this, why does she seem so confused when the Narrator tells her to piss off? It becomes more rational in light of the reveal: since she was ''Tyler'' girlfriend, from her point of view the same guy alternatively sleeps with her and treats her like crap. She's completely confused for a good reason, but from her point of view, that's ambiguous enough to not just compel her to flee the guy.

** Also, Tyler says he dialed star-69 to call back, but his phone doesn't have a star button.
