Continuity mistake: When we see Christmas Flint with her dad and Miss Rayleen for the first time, she's watching them bicker, her chin perched on the back of her hand. Which hand, though? It's her left hand for the greater part of the scene, but in the shot when Jim Gaffigan is saying "I got to find my pants. You move my pants?" it's the right one. (00:05:00)
Continuity mistake: When Santa tells Noelle he's anxious about inheriting his dad's role, the position of his arms is inconsistent between front and side shots.
Other mistake: There is a wall mounted mailbox on the interior side of the deck wall, not easily accessible to a mail carrier. Wall mounted mailboxes are typically placed on or next to the front door or a more accessible location. The location of Richard's house would also question why a roadside mailbox was not required. (00:03:35)
Other mistake: The Burglar (while tied to a chair and talking about "My Darling Clementine") says, "Apex of Ford's art, you feel me?" Vikar (James Franco) responds, "I feel you." The movie starts in 1969, but rapper E-40 (Earl Tyrone Stevens, Sr.) - "slang master" - supposedly created the expression "you feel me" in the early 1990s. (00:19:53)
Continuity mistake: The inspector is showing the singer the gruesome images of her friend. As he says "It's how we identified the remains", she raises her right hand, but in the next shot it's with the left hand that she's touching her lips. (00:04:45)
Factual error: The protagonist wakes up supposedly at 5 AM of December 2nd in New York City. Outside, the sun is shining, almost two hours too early. (00:00:15)
Continuity mistake: The dorky protagonist just bumped into the bike shop girl. She tells him "It's all good, man", to which he replies asking how's the bike. Behind him, a woman with a dog makes her appearance. Over 10 seconds of conversation pass, and the woman is still where she was, but in the shot that follows, when she says "I'm Cate, by the way", the woman warped past him, and is now behind her to the opposite end of the sidewalk. (00:07:15)
Continuity mistake: Higinio emerges from his hideout to strangle with the measuring tape the man who is raping his wife. During the scene, the tape is above or below the shirt's collar and with a dangling loose end coming and going. (01:02:20)
Audio problem: The FBI agent is in pursuit of a suspect in a hospital, once he enters the stairwell he draws his Glock handgun, and a click can be heard for a safety disengaging. Glocks are striker fired, they contain no external safeties that can be manipulated that would cause a sound. A sound can also be heard after the gun is already drawn from the holster, representing a holster draw sound. (00:22:22)
Factual error: There are roars of thunder without any visible lightning. Next, two bolts of lightning occur at the same time as the thunder booms (but the thunder continues after the lightning strikes). People see lightning before hearing thunder. (Although the two do happen at approximately the same time, light travels faster than sound which is why people see lightning first). (00:12:45)
Other mistake: Nicole was standing up holding a round cake with both hands and was able to tilt the cake down about 45° to show others the top without the cake sliding off the plate - or any icing shifting.
Continuity mistake: In the sequence with the pigeon that tries to topple the severed hand off the gutter, twigs are right next to its fingers or not, depending from the angle. (00:06:35)
Continuity mistake: In the prologue, the Nazis storm the Bresson residence. The elder Professor Bresson is sitting at his desk, back turned to them. There's an open fountain pen next to him, right by a paper sheet, but when Bresson answers rather defiantly to the bad guys, the paper sheet suddenly has disappeared. (00:02:15)
Other mistake: Glen/Charlie poured gasoline all over the vehicle he killed Sandra in - including its soft convertible top - but the flames stayed around the car's perimeter. (00:50:54 - 00:51:26)
Continuity mistake: The bartender pours two beers that have no foam on the top. When the beers are set on the table they have about one inch of foam. When the camera angle changes there is no foam. (01:18:45)
Continuity mistake: The protagonists escaped from captivity and managed to return to Harry's palace. Luka decides to leave to go look for his mother. Harry seems to send him off, and he is standing in the middle of the stairs, about 4 steps below the guard. Harry at this point is in close-up; the guard is not visible, and at the next cut somehow Harry shoves him off as if he were standing directly behind him. (00:16:00)
Continuity mistake: When the group go to the DARPA HQ during the post credits scene, pay attention to the doors as they enter the lab - the doors we see on the outside do not match the doors we see on the inside, revealing the scene was shot on two separate sets. (Most noticeably, the windows on the doors get significantly narrower once they are inside the lab).
Continuity mistake: Sira pours Sprite into a glass until it is about three-fourths full, but the glass is closer to half-full when he hands it to his mother. (00:02:00)
Other mistake: The on-line "Ventura Space Competition Entry Form" asked for the applicant's "full name", but did not have a space for "middle name." The format of the questionnaire was also inconsistent. There were forced-choice (yes or no) health-related questions and age groups (21-30, 31-50, and 51-65) but they were unequal (9, 19, and 14 years, respectively); the age groups should have been consistent, such as a span of 14 years per group (21-35, 36-50, 51-65). "Are you in good health?" was open-ended. (00:21:55)
Continuity mistake: The girl and guy are in a hotel room and she kisses him good bye. You see her go out of the door and the door handle is on the left side and no chain hanging. Then when you see the door a few seconds later the door handle is on the right and the chain is latched.
