Plot hole: The premise is that the back-story is a fabrication, including the five being placed together in the police line-up and in custody in order to get them to work together. But in the flashback of Keaton in the restaurant, it is Dave Kujan who takes Keaton in. It is inconceivable that Kujan would be complicit in the staging of the line-up (and doesn't fit with the plot). And if Verbal is inventing it, then Kujan is going to know it didn't happen. It doesn't make sense and undermines the plot.
The Usual Suspects (1995)
1 plot hole
Directed by: Bryan Singer
Starring: Kevin Spacey, Benicio Del Toro, Gabriel Byrne, Kevin Pollak, Chazz Palminteri, Dan Hedaya, Stephen Baldwin, Pete Postlethwaite, Giancarlo Esposito

Continuity mistake: Right before they rob the police car, a Boeing 747 (four engines) is seen in shots of the plane coming into land. When the plane is shown from behind, it is a Boeing 767, with only two engines and fewer main landing gears. (00:30:10)
Cop: I can put you in Queens on the night of the hijacking.
Hockney: Really? I live in Queens. Did you put that together yourself, Einstein?
Trivia: The way none of the characters can keep a straight face when reading out the card in the line up was not scripted, but resulted because the cast had had a rather good lunch prior to filming, which included some wine, and were unable to get through what was scripted as a serious scene with straight faces, because of the nature of the scene - supposedly very serious, but they were being asked to utter this rather absurd (and obscene) phrase. Benicio Del Toro also frequently broke wind during the scene, hardly helping the serious tone.
Question: Why do the gang decide to kill Kobayashi (when they are dressed as repair men and shoot the other two men in the elevator)?
Answer: The gang decides to kill "Kobayashi" in order to get out of being forced into this dangerous gig, and also because the guy knows way too much about them (as shown by the personal dossiers they were given at the pool hall).
Answer: Because Verbal Kint is a sociopathic habitual liar and it fits his style of story telling.





Suggested correction: It's for effect to show they were hanging out around the airport for more than a bit.
There's no evidence this was meant to be a montage scene of various planes. The cuts they did have in the first angle were of the same plane getting closer to build suspense. Same for the other angle. Plus, there's no scenes or shots of "them" waiting.
