Continuity mistake: At the skate park (which is supposed to be Thursday after school), Max is wearing the clothes he wore on Wednesday and Friday - not the clothes he wore in school on Thursday.
Continuity mistake: Throughout the movie in several scenes the living room has 2 couches even up until the Parks are getting ready to leave for their camping trip, 1 big one and one small. The very next scene when the Kims are getting drunk, the small couch has disappeared. This must be to make room for the Kims to slide and crawl out from under the table. The strange thing is when the Parks come back home, they don't notice that one of their couches is missing. It remains missing until the end.
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)
Other mistake: When the characters go to the Himalayas, the whole time, like for 20 mins, including the confrontation scene, they are all wearing casual, short-sleeved shirts. You can see Mr. Burnish's henchmen wearing winter clothing, while the main characters don't freeze to death. They only start getting cold after a long time.
Other mistake: The opening (like most of the movie) does not make much sense, so you can pick your kind of mistake here; the special effects are cartoonishly bad throughout the big firework explosions. When John Abraham is knocked through a window by a rocket (which takes off with a 270° turn without even rising) to the face, he gets up unscathed and starts screaming for Junky and Chandu. The camera moves from them to him and he's running with the girl in the red costume in front of him (which was way behind, safely, when he crashed through the window, so already that is wrong), and then there's a wider shot. In that shot, you can tell that Adams is bumping into the same people as before and the distances between the extras are all wrong. (00:06:35)
Continuity mistake: During the credits, Amaia Salamanca kisses her girlfriend cupping her face with her fingers that change position between shots. (00:02:30)
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: Zeke is in the kitchen with his daughter. He is checking out Dick's driving license; in the close-up he is holding it with his left hand, but in the following shot, as she asks him "Where'd you find it?" he is holding it in his right hand. (00:10:15)
Factual error: During the opening credits, Alec Baldwin and Selma Hayek are driving back to New York. They pass by various buildings, one shot being entirely devoted to a dilapidated Blockbuster video store. That shot must have been archive footage from the UK, since you can see the realtor sign by it, and it's from Carter Jonas, a London based firm, and gives an 01962 phone number (Windsor).
Continuity mistake: After the cartoon segment, Deni entertains some playful banter with his girlfriend and takes off, putting a shirt on while he runs. When the neighbour asks him "Late again?", the guitar strap is on opposite sides of the instrument as the editing switches to a reverse shot. (00:06:40)
Continuity mistake: When Aunt Sarah arrives, she dumps her luggage in the hands of Jim and then passes him to his right, leaving him between herself and the door. In the reverse shot, Jim is on the opposite side. (00:29:15)
Continuity mistake: The protagonist is at the lunch table with his auntie, and is trying to get her to fund his 'enterpreneurial' efforts. After the prayer, she asks him "You want some hot sauce?" Eddie Murphy goes from having his hands joined to having them on his hips. (00:20:25)
Continuity mistake: After Sara's mother sits at the table, the left side of Sara's hair suddenly has two clumps of strands running down her cheek and flipped in front of her chin. Sara's hair changes a few times with different camera angles. (00:44:52)
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.
Continuity mistake: She is walking from the sofa barefoot, but when she puts down the school year book on the glass table you can see that she has slippers with diamond stones on. (00:28:00)
Continuity mistake: When George gets shot, he lies flat on his back. When Gloria walks in on the scene, there's a closer view of him and he is lying on his side. (01:18:45)
Continuity mistake: Molly interjects as the journalists are putting Katherine in a tough spot: she slips a hand around her waist in the close-ups, but the hand is not there in the wider shot. (00:46:40)
Visible crew/equipment: Ali's assistant sits in her office as she goes to apologise to him. But in the reflection of his glasses you can see the green screen which I suppose is meant be the windows of the office. (01:32:00)
Continuity mistake: When we see Erin and Leah for the first time, they're talking and smoochin'. Despite the conversation being continuous, the reciprocal position of their hands changes abruptly between shots at the beginning (Erin's hand is on the outside of Leah's, then on the inside, then outside again). (00:05:25)
Continuity mistake: Gabriela's luggage crashes down the slope into the vehicle of the beefy co-protagonist. During the scene, the bra on the pickup's hood is positioned in an obvious different way (also coming lower onto the fender's arc) between shots. (00:13:00)
