Insomnia

Continuity mistake: When Dormer and Eckhart arrive by seaplane the pilot opens the door for them but then vanishes between shots (just as Detective Burr greets them). (00:04:40)

Jack Vaughan

Continuity mistake: When they first interview the boyfriend at school, you see the boyfriend lighting a cigarette, taking a drag, and exhaling smoke. The camera angle changes and the smoke that was just in front of him is gone. (00:18:25)

MCKD

Continuity mistake: When Al Pacino runs along the boardwalk towards the floating logs, following Robin Williams, in the shots showing him from behind he is running with his arms spread at a considerable angle, while in the shots showing him from the front, he is keeping his arms into his body. (00:25:20)

Continuity mistake: In the scene on the ferry, when Williams and Pacino are talking, in the shots showing Williams, Pacino is facing the center of the ferry frequently, while immediately afterward in the shots showing Pacino, he is facing Williams again.

Continuity mistake: When Dormer and Finch meet up after the interrogation, Dormer slams Fince against a metal support beam and the position of his hands of Finch change from being pressed against Finch's left cheek to being pressed against his neck/shoulder area as the camera angle changes. Happens about 3 times during scene.

MCKD

Continuity mistake: When Robin Williams is being questioned by the police for the first time, one of the cops is talking to him. Very soon afterward the cop leaves the room and is walking away. We see the cop in the distance in another room, yet we hear the cop talking to Robin Williams again as Al Pacino shuts the door. Almost immediately, the camera angle changes to the cop as he finishes talking. He is standing in front of Robin Williams again.

Continuity mistake: When Dormer first goes to Finch's apartment, you see him taking out his gun and holding it in his right hand as he starts walking down the hallway. Camera angle changes and the gun is no longer in his hand. Camera angle changes again and the gun is back in his hand.

Continuity mistake: During the final fight, Pacino & Williams shoot it out in a small boathouse. Williams is shot and rolls into the water (dropping about 2 foot before splashing in). Pacino walks out of the house and meets the female officer. The camera pulls back to show the boat house on stilts about 20 feet out of the water.

Continuity mistake: When Al Pacino and Hilary Swank are talking outside of the building, the shots of Swank show the jeep in the background. Look at the front tyre: completely flat. A few scenes later it is being driven with a perfectly inflated front right hand tyre.

Suggested correction: The tyre LOOKS like it is below some sort of curb line. I kept thinking it was flat too.

Continuity mistake: When Rachel and Dormer are in his room the night before he is going to leave, she takes a sofa cushion down from the dresser; the camera angle changes and she has two cushions.

Will Dormer: You shouldn't knock misdemeanors.
Ellie Burr: Oh, but it's small stuff. It gets so boring.
Will Dormer: It's all about small stuff. You know, small lies, small mistakes. People give themselves away, same in misdemeanors as they do on murder cases. It's just human nature. Aren't you gonna write that down?

Question: Why does Dormer switch to a backup gun while chasing the killer in the fog? It is never explained.

aftucci

Answer: Plot device to make Ellie look like a super sleuth remembering Dormer even carries a backup. When Hap and Dugger were comparing guns Hap says he and Dormer both carry S&W .45s. This makes the 9mm casing Ellie found a complete mystery to everyone else. So why the switch? Dormer's primary might be empty, but this is the first time Dormer shoots and all the characters act like there are only two shots fired in the fog, so for it to be empty he would have to be terribly sloppy. If he's so bad he forgot to load his gun it's equally likely he left the safety on. Maybe Dormer is just so used to being a dirty cop he instinctively uses the backup whenever possible to create an alibi. Ultimately, there is no explanation for this in the film, and if blink you don't even see the switch and are very confused when the 9mm casing shows up in the first place, if Nightmute carries.40, and Dormer .45, then 9mm has no place at all.

In the Netflix version with subtitles, when Dormer fires his primary weapon, the subtitle says "gun clicks." Dormer briefly looks at his gun and then pulls his secondary weapon. Nolan may have intended this to be ambiguous so the viewer doesn't know whether it was an accident or intentional (Nolan would never leave a "mistake" in the final edit - in fact, in interviews, he said he watched the movie at least a hundred times while editing), but the subtitles seem to put this debate to rest.

Chosen answer: Because he ran out of bullets in his first gun.
