How we cite our quotes: All quotations are from Fight Club.
Quote #1
[Opening credits inside the human body. Camera travels through nerves and blood vessels, before coming out through the pores in the main character's skin.]
The movie literally starts inside our main character, with a computer-generated title sequence sweeping through his vessels and organs. That's a way to explore him physically, and the rest of the movie is about exploring this guy mentally.
Quote #2
NARRATOR: I know this because Tyler knows this.
This line is our first clue that our narrator and Tyler are the same person. Without knowing this, you assume they're just really close buddies. They tell each other everything. But the line takes on a whole new meaning once you know the twist.
Quote #3
NARRATOR: People are always asking me if I know Tyler Durden.
Contrasting with the last line, this line throws us off a bit as to the narrator's identity. Why would people ask him if he knows Tyler Durden if he is Tyler Durden? Of course, we later learn that most people in other cities don't know what Tyler Durden looks like.
