Plot hole: When Charlotte kissed Naveen at the end, she should've turned into a frog as well because she was no longer a princess.
Suggested correction: When ordinary people kiss a frog, they don't transform into anything. (Perhaps they die from infection after a few days.) Charlotte was just an ordinary person. Tiana was chosen. She wished upon the star. Naveen and the consequences of kissing Naveen were a result of Tiana's wish.
Suggested correction: How? She was no longer a princess.
Tiana turned into a frog because she kissed Naveen without being a princess, so Charlotte should have, too.
Visible crew/equipment: While Barnum and Phillip sing "The Other Side" Phillip uses two stools to get up and down from the bar top. When he steps down from the bar top, in this wideshot (also the first shot of them in the pub and other shots) the two upright stools Phillip used are secured with additional support, note the floor area underneath the stools' legs have the same pattern as the rest of the floor, though we can see the outline where the pattern's lines don't match up. Additionally, we also see three actors' marks (in the shape of an "L") on the floor in front of the bar, which will be where Barnum and Phillip will stand when they agree on the ten percent.

Revealing mistake: In the soda shop, the waitress turns off the lights with her elbow because her hands are full, but she misses the light switch by 6 inches. (00:55:10)
Continuity mistake: Angelica has flowers on her dress. During the wedding, they disappear and reappear between shots.
Continuity mistake: In the scene just before Miss Piggy and Eileen get fired from the department store, Miss Piggy is watching Kermit and Jenny hug. She then bends a metal pole in half and starts hitting a barrel with it. When she first starts hitting it, the pole she is hitting it with is very thick(much thicker than the one she bent in half), is a different colour and not bent in any way. In the next shot the pole is thinner,longer and looks like the one she originally had, but it is only bent at the top whereas Miss Piggy bent it in the middle. In the next shot of her after that, the pole is now thicker (but not as thick as the first one), is not bent and the colour has changed again. Also if you look around the area where Miss Piggy is, there is only one type of pole lying around, so where did the other two come from? (00:30:15)
Visible crew/equipment: Jareth says, "Sarah, don't defy me," and tosses the snake at her neck. In the next shot facing Sarah as she holds the snake, a crew member's hand is seen holding the end of the 'snake' below her right shoulder. (00:13:25)
Continuity mistake: Truly crashes into the pond three times: first when the kids are playing in the road and she takes them home, second on the day of the picnic when she says she has nothing else to do and will go on the picnic too, and third at the end of the film when Potts finds out he is rich. In the second of these three, when Mr. Potts carries Truly from her car in the pond, the end of the ribbons on the back of her dress gets soaked in mud, but when you see her again at the beach there is no sign of the dirt.
Continuity mistake: When Troy is in the locker room with his teammates, Chad is handed the framed photo of Troy's father and there's a white sticker on the back of the frame. In the next shot, when Chad gives the frame to Troy, the sticker is gone. (00:58:50)
Continuity mistake: When the twins are singing about Brad for the talent show, and Michael was playing the piano (you have to listen and watch), his hands are suppose to go across the keys but he is still doing the fake up-and-down-hand-move.
Continuity mistake: In the beginning while Dorothy is still on the farm, she walks along the pig pen fence and then falls in. When Bert Lahr picks her up out of there her dress is perfectly clean. (00:03:45)
Continuity mistake: Before the school bell rings, Jason asks Ms. Darbus for her favorite summer memory. When everyone turns to look at him in the shot from the front of the class, there is a book under Troy's desk, which is not there in the previous or following shots. (00:01:25)
Revealing mistake: When Tallulah and the girls are acting in the Fat Sam's Grandslam song look at Tallulah as they sing the 'Ra da da da da da' bit. She looks straight into the camera.
Deliberate mistake: When Eliza is about to be bathed, the mirror keeps turning around between shots to avoid reflecting the filming crew.
Other mistake: Based on the location of the barber's chair with the picture window in Todd's barber shop and the layout of the exterior of the building, there is no possible way that the chute behind the chair would be able to dump the bodies directly into the basement without going through the center of Ms. Lovett's shop.
Continuity mistake: In the scene where they go to Elwood's apartment, Elwood puts on a 78 RPM Decca Louis Jordan record. The record is entitled "Saturday Night Fish Fry". But the song that plays is "Let The Good Times Roll".
Revealing mistake: When the kids step out of the water and walk towards the house, the floor is already soaking wet from previous takes.
Continuity mistake: When Jingle, Jangle, and Mrs. Claus pay a visit to Mother Nature, Mother Nature calls her sons beside her - Snow Miser and Heat Miser. She then turns to Snow Miser and asks him to allow a little snow fall in the South, and then turns to his brother, Heat Miser, and asks to allow just "one Spring day at the North Pole." The words are correct dialog, but she should have said each of those lines to the OTHER brother. (00:39:40)
Other mistake: When the switch is thrown to electrocute Terrence and Phillip, it's pulled downwards. A few shots later, we see Cartman jump in to save T and P by turning the switch off. He also pulls the switch downwards instead of pushing it upwards. (01:06:05)
Visible crew/equipment: In the scene when Kermit confronts Doc Hopper he comes walking out of the bar. If you look at the top of Kermit's legs when he walks out, two pair of hands can be seen moving the legs.
Factual error: The sun can't rise out of the Pacific ocean when viewed from America, as seen when Danny is playing the clarinet. (00:01:20)
