1.The Tyler flashes.
Before Tyler officially enters the Narrator's life when they're sitting together on the plane, he appears six times in the film. Once he's riding a moving walkway at the airport (that appearance isn't included on this list, since it's not hidden). Four of those times, Tyler appears as a subliminal flash
that occurs when the Narrator has a moment of frustration or anger during his insomnia daze. These, of course, create the foundation for Tyler.
Below are screen grabs of all four one-frame Tyler Durden appearances -- once when the Narrator is mindlessly making copies... once when he's leaving his doctor... once when he sees Marla leaving a therapy session... and once during his testicular cancer support group.
2.Tyler as a waiter.
The fifth time Tyler appears? When the Narrator is in the middle of his early traveling montage and he's watching TV in his hotel room. A group of waiters on screen all say "Welcome." If you look carefully, Brad Pitt is in the front row of waiters
, on the far right
3.No incoming calls.
This is a quick, subtle hint early on that Tyler isn't real. When the Narrator's condo blows up, he calls Tyler from a payphone, with no answer. Then, a few seconds later, the phone rings. As the Narrator goes to answer it, the camera zooms in on some text on the payphone that reads, "No incoming calls accepted." In other words -- Tyler could not have called him back, because this phone cannot ring
During the course of the movie, Tyler and the Narrator intentionally dress in opposite ways -- Tyler is flamboyant, the Narrator is corporate and buttoned-down. The only place they're identical: Their boxers.
When the Narrator is ordering IKEA furniture at the beginning of the movie, he's in plaid boxers.As soon as he moves into Tyler's house, he begins wearing white boxers... the same exact ones Tyler wears
as he bikes around the house.
This is extremely, extremely subtle. But when Tyler is fighting the owner of the bar, when Tyler gets punched in the stomach the Narrator ever-so-slightly doubles over and winces in pain.
It's one of the only times you ever see him visually react to what happens to Tyler
. I guess it would be too over-the-top if all of a sudden his face became all bloody here.
I have a lot of beef with the car crash... I know they explain on the DVD commentary how a figment of your imagination can drive a car into a ditch... but it's always felt a little too forced to me.
(It's almost too much of a fake out. We're willing to believe the Narrator beat himself up in those first few fights, that he chemical burned his own hand, that he went around the country setting up fight clubs. But that he could have that argument with himself while driving a car off a road? It's just one leap too far.)
Anyway, in the scene, here are two hints that Tyler doesn't really exist. When the car pulls up, the Narrator gets in the driver's door, and Tyler follows through the same door. But when the car crashes and flips over, Tyler gets out of the passenger side... and pulls the Narrator out of the driver's side.
Because the car's flipped it's hard to figure that out... damn near impossible in the moment.
7)The Narrator wanders the house while Tyler and Marla noisily have sex upstairs. When the detective calls and the Narrator answers the phone, the sounds of the lovemaking instantly stop
8)When Tyler and the Narrator hit the first car with baseball bats, Tyler hits first, but the alarm is triggered only after the Narrator hits.
9)When the Narrator enters the house prior to seeing the news report of the happy face on the building, he is carrying one of Project Mayhem's folders.
10)When the narrator gets on the bus with Tyler, he only pays the fare for one person.
