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.
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.
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.
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: 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: The orchids in the vase in the center of the table are spread differently in views of Erasmus or Paul. (01:11:12)
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)
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: 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)
Continuity mistake: Felix on his skate jumps over a rolled-up rug some movers are carrying in the middle of the street. He jumps and the street is in the shade, he skates away and the street is full of sunshine. (00:01:30)
Continuity mistake: On his way to work, Antonio meets his ex Camilla.During their conversation, as it's particularly evident in the subway stairs sequence, passersby vanish every time the camera cuts to another angle. (00:08:00)
Continuity mistake: When Phil heads to the Puppet Pleasure place early in the film, the positions of the shadows change around the vehicle parked out front in the close up, revealing the time laps between filming each shot. (00:06:30)
Continuity mistake: After Willoughby wrapped a necktie around Don's wrist and crossed the ends to hold it together, it fell apart when Don lowered his arm. But the necktie was securely wrapped when the camera shifted to showing Don putting his arm around Willoughby's back. (01:36:40)
Continuity mistake: When the police knocks at the door of Simon's trailer, Jean-Hugues Anglade 's arm changes position between shots as he talks to his daughter.
Continuity mistake: Violet's mom is hot combing her hair at 5 AM; as she performs this operation on the left side, the right side has straight black hair all in front of the shoulder. When Violet tells her that dad is coming, she moves to the right side. Sanaa Lathan's hair now is suddenly all behind the shoulder. (00:05:20)
