Revealing mistake: After most of the people trying to hang onto other people holding onto the ascending helicopter fell off, a downward view from the helicopter showed a man effortlessly hanging onto the landing skid and a woman just as effortlessly grasping his jacket's shoulder. (00:02:50)
Continuity mistake: Right at the beginning, two dumb kids looking for drugs are forced to make a spontaneous donation to the cult. Before the stream starts the pink polo one does not have the scooter on his shoulder, which is back when the stream starts, then off again.
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: After the alien abduction, Emmet plans to lead a rescue mission and opens the gate asking "Who's coming with me?" During the sequence, the shadows change completely. At first he is not casting much of a shadow, then it reaches the metal doors, then it stops midway towards it. (00:20:55)
Continuity mistake: Watch the back seat during the pullover scene. The 3 in the back aren't always there together. Joe's by himself in some scenes. The ladies are missing Joe between them.
Continuity mistake: The tassel on Molly's graduation cap disappears at the end of her speech, then reappears later.
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)
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)
Continuity mistake: When the yeti takes the air conditioner and the cousin calls the police, it goes from daylight to night time in seconds.
Continuity mistake: A tipsy Emma puts her feet up in first class. The flight attendant tells her that it's unacceptable; her right hand is high-low-high again between shots. (00:08:05)
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: 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)
Continuity mistake: Scooby and Shaggy are lying face down on the massage table when the zombies arrive. Shaggy has his robe lowered baring the upper back, but in the close-ups you can still see the robe up covering his shoulders perfectly. (00:28:00)
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: 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: When Pinky barges into the protagonist's home, multiple times (for instance when he sits in front of her) her pigtails move behind her shoulders from the front and vice versa between cuts. (00:06:00)
Continuity mistake: At the beginning of the movie, the two knights are walking across the courtyard to get on their horses. When they mention the falcons' names, a young lady wearing an orange striped cape curtsies before them in passing. A couple seconds later during the close-up of girls ogling them from distance, the same lady passes in the foreground, coming from the opposite direction and in a totally different spot. (00:00:55)
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)
