Visible crew/equipment: The camera crew and the boom mic operator can be seen reflected in the store windows as Mr. Pink is running from the cops.
Continuity mistake: When they bring Marvin Nash to be tortured, his hands are cuffed behind his back. They start kicking him and his hands are then seen cuffed in front. Then, they switch back just a few moments later and his hands are back behind his back again.
Continuity mistake: In the scene where Mr. Pink is running away from the police, he gets hit by a car. He pulls the woman out of the car and leaves the bag on the ground. The shot changes to the police, then back to him and the bag is gone even though he's still trying to open the door. (00:21:00)
Continuity mistake: During the torture scene, Mr. Blonde gets his sleeves bloody, but when he is holding the ear, the blood disappears. A few seconds later, the sleeves are bloody again.
Continuity mistake: When Mr. Blonde is in the warehouse with the cop, it shows close-up of the cop, and he has blood on his forehead on the left side. After Mr Blonde slaps him in the face, the blood has disappeared. It reappears later.
Continuity mistake: During the chase, we see that there are only three cops (we see a head-on shot of the three cops with an empty sidewalk behind them), but when Mr. Pink opens the car door and starts firing in the direction of the cops, the first three cops (the thin ones) scramble back around the corner. Just then, a fourth cop (the fat one) pops around the corner from nowhere and gets shot.
Continuity mistake: Just after Mr. Pink stops Mr. White and Mr. Blonde from fighting, watch Mr. Blonde's tie. It's secured with a tie pin - initially rumpled so the top bit "bumps", then smooth for a couple of shots, then back to having a bump. (00:34:00)
Trivia: When we see Eddie on his way to the warehouse there's a clue as to the rat's identity - an orange balloon behind the car.
Visible crew/equipment: When Mr White gets out of his car after it crashes to shoot the cops coming in their patrol car, keep an eye on the rear passenger window of his car where a boom mike can be seen. (01:13:10)
Continuity mistake: In a scene near the end, Joe arrives at the warehouse and tells everyone that Orange is the informer. We frequently see Orange on the floor, however the blood patch he is lying in changes from wet to dried to very wet to larger and smaller and back and forth. Also sometimes there are bullet casings around him or the magazine he dropped depending on the shot.
Continuity mistake: In the "Mr. Blonde" segment, Vic takes a cigarette from a case on Joe's desk and puts it in his mouth. Soon after he takes it out. Then there is a shot from the hallway and the cigarette magically appears back in his mouth, where he takes it out for a second time.
Continuity mistake: During the flashback of Mr. Orange's "commode story", Orange presses the button to start the hand dryer with one finger and the rest of his fist clenched. In the next shot, his thumb is instantly extended, as well. (01:13:10)
Revealing mistake: When Mr. White shoots the two cops inside their car and Mr. Orange watches the scene astonished, dummies replacing the cops are visible for half a second sitting inside the vehicle just before the windscreen gets hit by the bullets.
Visible crew/equipment: When Mr. White and Mr. Orange run away after Mr. Brown's death and killing the cops, crew members are visible in the background hidden behind the truck.
Visible crew/equipment: When Mr. Pink escapes from the cops and he's hit by a car, you can see the crew members in the background watching the scene.
Chosen answer: Having just been shot a second time, he was probably dying by that point. He'd done many extremely questionable things - even murdered an innocent mom - and stood by as other terrible crimes were committed in his presence. He'd grown close to Mr. White, who'd just murdered two friends and taken a bullet for Orange's sake - even as Mr. Orange was betraying him all along. So partly this was about his attachment to Mr. White, and partly a death wish stemming from his own guilt about his actions. He knew full well what would happen but told Mr. White anyway, disregarding the consequences.
