Continuity mistake: When Frank the dog is growling at the agent in the park his teeth are fine but later talking to Zed he is told he can have better dental. He smiles and his teeth are horrible. (00:23:50 - 00:31:10)
Continuity mistake: When the two brothers are frantically trying to get out of the car because the monster truck is barreling toward them (in slo-mo), you will notice that the tongue ring is missing from the one brother's tongue. Odd mistake seeing as his character is centered around the tongue ring. (01:27:05)
Continuity mistake: When Meryl Streep "blasts" Goldie Hawn with the shotgun and Goldie falls into the pool of water, she falls in backwards. However, when we see her get up, she is getting up from a face-down position. (01:05:25 - 01:07:10)
Continuity mistake: William H. Macy makes dinner plans with the Mayor and writes "Dinner with the Mayor" on the dry erase board in his office. He writes "Dinner w/ the Mayor" in the "Tuesday" slot. Then an intern comes in and accidentally wipes the appointment off the board with her shirt. Macy yells at her and tells her to rewrite the appointment on the board. The whole premise of the joke and pretty big part of the movie is that the intern rewrites the appointment in the wrong day, thereby causing the Hollywood people to miss dinner, enrage the Mayor and his wife and have the town turn on them. When the girl walks away however, the appointment is clearly rewritten in the correct day (Tuesday). This ruins the whole misunderstanding because although the appointment is in the wrong day later in the movie, at the moment the joke is supposed to be set in motion, there is no mistake.
Continuity mistake: Professor Sheldon 'Shelly' Oberon sprains his right ankle when escaping the baboons by jumping to another bridge. Ming Fleetfoot wraps his left ankle later on when they are by the river. (01:11:38 - 01:14:00)
Continuity mistake: During the detention scene, the teacher comes in and you can see there isn't anything on his rear end. As he leaves, you can see toilet paper hanging from his rear. This was because a scene never made it into the movie where the teacher's office is in the mens restroom. Also confirmed on cast commentary.
Continuity mistake: In the tryouts scene, the stripper's top suddenly changes between when she leans in towards Torrance and when she crawls across the table. [This is because in the extended version of the scene, she takes off the top to reveal she is wearing an even more revealing one under the first. Still a mistake, but there's the explanation.]
Continuity mistake: During the fight between Aslo and Silas, Aslo is seen lying on his back in a closeup. But when the shot changes to a wide shot, he is suddenly on all fours.
Continuity mistake: When Harold Ramis is fighting Bill Murray to try to keep him from leaving the base, notice when Harold is on top of Bill choking him, there is a duffel bag under Bill's head, and in the cut-aways the bag is a few feet away. (00:47:00 - 00:47:45)
Continuity mistake: When Sam and Anton are finished fighting (Anton is in an upper-body cast), the arm support on his right keeps changing. First it's a short piece coming from the elbow, then it is a long piece coming from the side, and then back again.
Continuity mistake: When Cher is taking the driver's test, she bangs the mirror. But then, when she turns the corner, the mirror is whole again.
Continuity mistake: In the final chase scene, the yellow Hummer starts out with an open sunroof. As it barrels through the shantytown, interior shots of the Hummer show it with a large overhead bank of storage compartments, while overhead shots show the sunroof. When the chase finally reaches Gitmo, the Hummer once again is shown with an open sunroof. (02:11:50 - 02:12:55)
Continuity mistake: A couple of scenes after the baker's wife ripped off most of Rapunzel's hair, it has grown back to full length so that the prince can climb up to the tower on it.
Continuity mistake: Near the start, Mirabel is given a basket with items such as bucket and spade, windmils etc. When given the basket the buckets are towards her. When the shot changes the buckets are away from her. (00:07:15)
Continuity mistake: When the girl gives Litwak her phone to show him there is a replacement part on eBay, her phones shows that it is connected to WiFi. Litwak doesn't set up his router until later that evening, he has only plugged it in. (00:09:41)
Suggested correction: It's possible she's either connected to wifi at another nearby business, using a public wifi signal, or using a friend's phone as a hotspot.
Continuity mistake: In the pool scene where Mrs. Doubtfire picks up and throws a lime at the back of Stu's head, when Stu walks away and the camera goes back to Mrs. Doubtfire at the bar, the lime that she threw is still on the top of the stack of fruit.
Continuity mistake: During the scene where Zac Efron is talking to his girlfriend for the first time in the cafe, the reflection of her in the window does not match what she is doing in the scene. (00:25:30 - 00:25:35)
Continuity mistake: While Annie and Stacks are in the Stacks Mobile helicopter, Annie's seatbelt shoulder strap repeatedly changes from being over her shoulder properly to being under her arm. (01:03:00)
Continuity mistake: When Tom the Minion dressed as a maid is hoovering, he answers the front door by opening it towards him as does the minion who looks out of the door after Tom has been taken. In the scene with Gru sat on the steps in the rain, sad that Lucy is off to Australia, Agnes comes out with an umbrella, but now the door opens outwards.
Continuity mistake: When Kate and Carly are leaving Carly's apartment building and Carly goes to hail a cab, Kate is wearing a cream cardigan over her blue and white outfit, standing by the curb holding the dog's leash. The scene cuts closer and Kate is not wearing the sweater at all. (00:31:55)
