Factual error: Right at the start of the film, it shows the girls going up for the first day of school which would have been around Fall. It shows tulips blooming in the garden, but tulips only bloom during the spring. (00:00:55)
Factual error: Jonah Hill references "Chucky" from the movie Childs Play. This movie's period is set somewhere in the late 1970's. The movie Childs Play didn't come out until 1988.
Audio problem: When Mrs. Hudson finds a package for Sherlock instructing him to open it before the trial, she says "I never even heard anyone knocking" whilst handing it to Watson, but the line appears to have been dubbed over as her lips don't match up with the dialogue.
Factual error: Max could not have been accidentally shot when Annie drops the revolver. She dropped it when she was startled by firing it into the ceiling so the hammer would still be sitting on the spent/empty shell casing. The trigger or hammer must be pulled back in order for the cylinder of a revolver to rotate to the next live chamber.
Other mistake: Daphne's dad drops the Legitimate Tulip badge in front of her so she'll avoid getting hurt, but when we see him do that, he does it before the warning for the ball is heard and seemingly not looking at the danger (especially in the second shot, when he is peeking from the corner). So his action makes no sense. (00:16:55)
Factual error: In the bar scene there is a sign for Genesee beer. That brand never went west further than Pennsylvania.
Continuity mistake: On Friday, Lana waves bye to Aakif on the doorsteps; he has both hands on his belt in that first wide shot, but when he replies and waves back, his left hand is in his pocket. (00:09:50)
Factual error: Simon receives an email notification at the dinner table from Blue on his cell phone. The cell phone screen indicates that the time is 3:20, which is inaccurate for a mealtime because it is already dark outside and crickets are chirping when he excuses himself to go outside to get some air. (00:28:10)
Plot hole: *SPOILER* Calvin's twin sister and mother were killed years earlier in an automobile accident. Calvin kept going to his doctor with "new symptoms", insisting there was something physically wrong. Dr. Collins told Calvin, "Your health issues aren't physical. I thought sending you to that support group would give you a better perspective." The doctor should have referred Calvin to a psychiatrist for a diagnosis and, if appropriate, the psychiatrist would recommend therapy or a support group. (00:10:15)
Continuity mistake: When Rick and Kirsten are at the game, just after they shout at one of the players, Kirsten drinks from her cup, but in the next shot, the cup is suddenly back in the armrest holster. (00:33:40)
Continuity mistake: Danica gets to work at the beginning of the movie, and her coworker passes her a folder. The folder keeps moving from under her arm to her hand, back and forth between shots. (00:03:00)
Continuity mistake: The orchids in the vase in the center of the table are spread differently in views of Erasmus or Paul. (01:11:12)
Visible crew/equipment: When Zoe walks into Anderson's office and tells him she's meeting Maya at the apartment, just as Zoe says, "Uh oh," there's a visible blue T-mark taped to the floor. (00:49:05)
Continuity mistake: Darren is smoking salvia in the first scene in the hotel room. He lies down on the bed; his hand changes position between shots several times. (00:03:30)
Continuity mistake: Paolo's wife finds the text message of the girl calling him "my eternal love." In close-up she is holding the phone with the index finger at the very top of the phone, but in the previous and following shots the index is far from reaching that spot. (00:09:15)
Other mistake: After the three kids took the car and caused a 19-car pile-up on the 141, Social Services got a court order removing them from the home and parents were not allowed to see them. Social/Child Welfare Services try to maintain or preserve the family unit and view removal from the home as a last resort or in cases of severe neglect or abuse that endangers the child. Social Services would not be likely to take such drastic measures for this incident. The driver may have been adjudicated a PINS.
Continuity mistake: The three besties are in the car at the beginning of the movie, chatting. During the chat, the scenery keeps changing between shots without much consistency. (00:00:50)
Continuity mistake: Deanna is playing racquetball with her friend when she hits her in the lady parts with the ball. The two sit down by the wall; look at the bottle Melissa McCarthy is holding; it's practically empty, but in the closer angle when she sobs "What am I doing?" it is almost completely refilled. (00:09:50)
Other mistake: The protagonist finds out that his wife is cheating on him, and decides to try to dial the killer. We see his phone number, it's 328 241... Later on, after visiting his brother's parish, he tries to contact his 'frenemy' again but the number now is 386 909.etc. He can't have changed number in that short while (and the protagonist wouldn't know anyway). (01:03:10 - 01:10:55)
Continuity mistake: In the vault scene arguing/fighting with Gunnar, Taj/Lars had a clump of hair sticking up in the middle of the top of his head during most front views, but not rear views. (01:03:10 - 01:04:11)
