No Name Given: Edward Norton's character is known in the script only as the Narrator, no name is given. This is a very popular trope - it is also used in
"Rebecca", "The Wretch"" and other works.
The City with No Name: Several other towns are mentioned in the film, but it is never stated where the narrator lives. Clues in the novel and film indicate that the town is actually Wilmington, Delaware.
Each character has a different
colour code: Tyler dresses in reds and yellows. Jack dresses in blue and grey. Marla is dressed in black.
