Revealing mistake: During the Miss United States Pageant, there are close-up shots of the audience and it is very obvious that in the balcony and back part of the audience, especially when seeing the 'men' with bow ties, they are fake - mostly cardboard cut outs. (01:22:50)
Continuity mistake: In the scene where Hank comes crashing into the building with Dick's car, the driver's side headlight is intact. They show the people in the building, and when the shot returns to the car, the headlight is dangling from its socket. (00:21:00)
Visible crew/equipment: When Émilien is chasing after the Ninjas on foot, they jump from a bridge onto the top of an orange lorry. The orange crash mats that the 'Ninjas' land on are visible in the overhead shots. (00:47:35)
Visible crew/equipment: When the Grinch is building the sled as he is putting the tin sheets on it there is an overview shot where you can see the shadow of the camera. (01:01:01)
Continuity mistake: When the girls figure out that Knox is after Charlie, and Dylan thinks of the picture and they zoom in onto "Townsend." The shot before the final shot of the photograph shows Knox's father's arm around Charlie, when in all the other shots, he has his arms above his head. (01:00:05)
Continuity mistake: After Heather is campaigning in the hallway of the school and giving out flyers, Buffy grabs the flyer and lets go of it, and is holding nothing. In the next scene where Buffy, Brenda and Cindy walk over to their boyfriends, Buffy all of a sudden has a folder, some books and a banana in one hand. (00:11:45)
Other mistake: When Big Momma is taking a shower, you can clearly see that the shower head is a mirror, with the water coming only out of the top, and when Big Momma bends over, you can also see her reflection in the shower head. (00:12:00)
Continuity mistake: In the scene where Pacha and Kuzco are drying off after they fall over the waterfall, the slot for the wearer's head in the center of Pacha's poncho is clearly visible when Kuzco takes it and uses it to dry himself off. Following the shot change between when Kuzco throws it and when it lands on the fire Pacha is trying to light, the poncho becomes just a solid green square towel with no hole for the wearer to put his head through, which is easy to see when Pacha hangs it backup on another tree. (00:32:07)
Continuity mistake: In the scene in the karaoke shop, watch the light through the window. Sometimes it's daylight outside, sometimes it's dark.
Continuity mistake: At the beginning "Pete" asks Violet for her autograph on a time card. She signs it and the "T" is not crossed, and when Pete puts it on the board it is crossed. Then at the end when Violet's dad buys it from Pete it is again not crossed. Also if you look at the "V" when she signs it and after Pete puts it up they are different. And lastly, when Violet signs her last name it is spaced but when Pete puts it up it is jumbled together. Her signature is different all around. (00:01:30 - 01:27:30)
Continuity mistake: When Memphis is driving Eleanor he backs up and hits the right rear-view mirror. He stops, leans out the window and sees that it is dangling. The very next shot it is back to normal and it stays that way for most of the rest of the movie. (01:34:34)
Revealing mistake: As Thomas crosses the viaduct gap, a rope can be seen pulling him.
Revealing mistake: When Jill and Cynthia meet by the water towards the end, Jill produces her gun and is told to throw it in. As she's holding it you can see the base of the grip and there's no magazine in it - hardly the most effective weapon... (01:26:45)
Continuity mistake: When the Devil is a teacher in the classroom she is erasing homework assignments off the board. In the close up shots (and maybe 1 or 2 of the far away ones) the board's partially erased. In most of the far away shots however, the board isn't erased. (01:01:50)
Continuity mistake: In the scene where they are in the all you can eat restaurant, when PaPa Klump farts into the candle causing the curtain to catch fire, when they first show the curtain after the 2 men put out the fire, there is clearly a burn mark on the edge of the curtain. However, when they show the curtain again, there is no burn mark. (00:17:25)
Factual error: In the scene where the guys are in the cafe, the waiter pours coffee, then puts his hand underneath the hot coffee pot. You cannot do that with a true glass coffee pot if your coffee is hot. (00:43:30)
Continuity mistake: When Greg is eating dinner with Pam's parents, his amount of sweet potatoes on his plate varies, sometimes there's many on his plate, other times there are less. (00:30:30)
Continuity mistake: When Mr. Tweedy collects the eggs, he adds check marks in Tuesday's column on the list he holds. In Monday's column it reads that chickens 276 and 277 did not lay eggs the day before. However, when the list is submitted at the end of the week, there are check marks in Monday's column for chickens 276 and 277, as if they did lay eggs.
Continuity mistake: In the gas station scene after Ellen learns that Phil has drowned, she is so distraught she forgets to put the gas cap on and we can see it on the roof of her car as she drives away. But when she arrives at the police station we can see that the gas cap is on. (01:10:20)
