Factual error: The movie is set in the year of production, but the "Grazia" issue on the magazine stand, featuring Gwen Stefani, is the March 31st 2016 one. (00:08:00)
Revealing mistake: When the black cat was going up the staircase and got to the first landing, it turned its head to look directly at the camera, then continued climbing the staircase. (00:08:13)
Continuity mistake: The three friends are at the hospital. As Raissa and Katia predicted, Dr. Victor is hitting on Paula. As they follow him, the stethoscope around Raissa's neck dangles differently from her neck between cuts, with the cup on top of her hair or under it, closer to the shoulder. (00:05:35)
Continuity mistake: During the introductory meeting with Nicole Kleiber, her glasses on the desk switch back and forth between open and folded. (00:26:20)
Continuity mistake: The kids are in the car with their dad, and despite the best efforts from the youngest, they are reached by his teacher. As the dad starts the "You were killing us" joke, his hand is on/off the steering wheel between shots more than once. (00:07:15)
Visible crew/equipment: Sara is at the front door video intercom. As the man from the Department of Sanitation is leaving, you can see crew/equipment visible in the reflection. (00:27:15)
Other mistake: In the scene with a leak in the kitchen, the woman fixes it by turning an isolating tap above the leak. However the water would have been travelling up the pipe to the kitchen tap and so that wouldn't have stopped the leak. (00:34:00)
Continuity mistake: In the opening scene, the blue car is parked on the far right of the screen or at least one car length from the doctor's front door. Dr. Huggins says goodbye to the couple with the baby, who walk toward their car. After the burglars-to-be (turned robbers) are shown watching from a distance, the camera returns to the doctor's front door. The blue car is now near the center of the screen and it drives away toward the right of the screen - going past the place it had been parked.
Continuity mistake: When Oliver is pushing injured Michelle in a chair down the hallway, they are approaching a long row of student lockers. When the camera shifts to a front view, they are near a stairwell and the short walls behind them are cement and brick with no lockers before the door. (00:41:05)
Continuity mistake: Jane Curtin is teaching to a rather seasoned class. One of those old hags says sarcastically "Because we really never do anything." As she says it, notice Eleanor turning towards her momentarily. She then turns completely, facing the opposite way, but at the cut she is repeating the turn from the beginning. Moreover, Moira's mouth closes after she says "Enough!" but the following shot on Curtin shows her still jaw-dropped. (00:04:05)
Continuity mistake: In the first shot of the choir (three students harmonizing on a note) the girl in pink holds the sheet with her left hand at the corner and the right hand in the middle. Cut to the wide shot, and she has the left hand in the middle and the right hand at its respective corner. (00:03:50)
Revealing mistake: When Maya Rudolph and Tim Meadows are in their car at the drive-in theatre, whilst Maya Rudolph says "We got Hubie Dubois spying on everybody", there is a close-up shot of the wing mirror with Hubie's car reflected in it, along with several other cars and a building in the background also reflected. Despite being a reflection, any text or numbers reflected in the mirror are not reversed. The number plate on Hubie's car is spelled out forwards, and the sign "Salem Drive In" on the building in the background is spelled forwards also, and not reversed as they normally would be in a reflection. (00:49:17)
Revealing mistake: The nefarious villain has just revealed to Prince Charming that he has kidnapped the princess, and shows her to the crowd as a big burly smurfy monster is holding her. The crowd in unison gasps and looks horrified...except an extra who just can't keep a straight face. (00:07:35)
