Continuity mistake: When Maggie's husband talks to the killer for a hit on Maggie II, watch as he switches the TV off; his left sleeve is down, then it's rolled up to his elbow again by the time he sets the remote down. Both sleeves change slightly the way they are rolled during the scene, but that's the most noticeable instance by far. (00:33:00)
Revealing mistake: During the negotiation for the second murder, Happy Anderson writes a "You HOPE she suffered" note, but shreds what looks like a "You HOPED she suffered" note - they are two different handwritten notes. (00:35:00)
Continuity mistake: When Jay asks Tommy T. about the moldy baloney, he is holding it with his right hand, both hands, right hand, both hands again. (00:03:20)
Continuity mistake: When Jordan and Rita are having ice cream together, Tina Fey's spoon is up/down between shots. (00:37:35)
Continuity mistake: Police Chief Jordan Sanders is looking for Jay Moore to tell him about his wife's apparent demise. Nosy neighbour Rita Grace invites him over to grab a bite. During this dinner scene, Tina Fey's fork carries food or not depending on the camera angle. (00:25:00)
Other mistake: During the close-up of Jay's Mega Ball's receipts (just after he got the phone from the manager of his franchise), you can see the two receipts have different numbers but the exact same transaction details. (00:21:25)
Continuity mistake: After the scene at the police station where the police chief tells his deputy about the cheesecake incident, Rita says hi to her neighbour Maggie, who is leaving for work. Maggie tells her that she and Jay are not going to be together anymore. Her hand changes position on top of the car door and suddenly is off the door entirely. (00:19:00)
Continuity mistake: While giving Jay a back massage, the masseuse's straps are up. Then her right strap falls over her shoulder and a grey strap is showing. Even though both of her hands are occupied, her strap goes back in place and the grey strap is no longer visible. (00:12:10 - 00:12:53)
Continuity mistake: When the first police officer looks at the body, Maggie's long hair is down her back, but is not when an officer takes a photo. (00:01:38 - 00:02:33)
Other mistake: The window looks closed, but even if the window is open, the woman ironing in her house across the parking lot would not be able to hear Jay and Maggie's argument from that distance, only muffled voices at best. (00:05:18 - 00:06:11)
Continuity mistake: During the short conversation with Jay, the hands on Maggie's wristwatch change from being on the opposite side of the crown (push-button) to pointing at the crown. (00:04:44)
