Continuity mistake: In the Adam and Zach part when they hit Ronna, the first shot (from the inside of the car) shows the windshield wiper hitting her head - then the second shot (from the outside of the car) you see the windshield wiper go all the way up, when her head should still be there.
Continuity mistake: When Adam and Zach are in the house with the cops and one of them has Zach up against the wall in handcuffs, the other red-haired cop comes through the door holding a long box. In one shot there's a piece of yellow tape on the end of the box, and a bar code sticker on the side. But in the next shot, the tape is orange and the bar code sticker has moved to the end of the box.
Continuity mistake: In the scene where the four guys are in the hotel room with the strip club guys trying to get in, the character who is talking to the kid through the door is wearing a sleeveless shirt, but when the camera changes angle, he suddenly has a orange jacket on.
Continuity mistake: The dialog in the scene where Simon is walking away after getting Ronna to cover his shift at the grocery store (which plays three times, once in each of the stories) only matches up to the movement of the character's mouths in one of the three versions.
Continuity mistake: When Todd is looking at the phony pills that Ronna brought back to him there are two shots, in between which a bunch of things change. The Santa hat on the back of the sofa moves and switches the direction it's laying, the pill bottle on the table goes from standing up to laying on its side, a jacket suddenly appears on the arm of the sofa, and various smaller things on the table appear and disappear.
Continuity mistake: When Simon and Marcus are fleeing in the red car after the shooting, Marcus has his right arm up on the seat back. In one shot he starts to put it down, then in the next shot it's up again. Then it just starts to come down yet again, and suddenly in the next shot it's completely down.
Continuity mistake: In both the first and last version of the stories, Ronna is in the bathroom with the door locked while the cop is trying to get in. In her story, the button is horizontal while he tries to open it; in Zack and Adam's version, the button is vertical.
