Audio problem: When Reynolds is salting the asparagus the camera cuts back to Alma and you can see Reynolds' hand moving in a different direction but the salt shaker sound is still playing. The camera cuts back to Reynolds, and he's holding the salt shaker again. (01:06:15 - 01:06:39)
Other mistake: When Catherine breaks into Crown's house, her assistants immediately get to work on the security panel. When the first assistant touches the panel, it falls off the wall and he has to quickly push it back into place.
Continuity mistake: At Riley's Garage, when Troy and Chad are about to rummage through the junk looking for the radiator cap, Troy raises his arms and his boxers are light grey, but next shot when he lifts the truck's hood his boxers are black. It's also noteworthy to mention that during "Boys Are Back," young Troy is wearing patterned boxers, though all other clothing is identical. (00:53:45)
Continuity mistake: When the devil is falling apart and his 2nd ear falls off, he tells Nicky he cannot hear him, and asks the demon by his side who catches it to put it back on his head. But towards the end, when the devil is reduced to no more than a mouth and 2 arms, he is able to have a conversation with his demons about what's going on and hear them perfectly. (00:52:05 - 00:58:50)
Suggested correction: Its not clear that they are actually having a conversation, he is just a mouth and two arms that can only talk and hold itself up. They respond to him because he can hear but he doesn't even respond to them. Its not illogical that Satan was talking to himself while deaf and falling to bits.
Continuity mistake: In the scene at the bar with Gideon when the black guy pours Gideon a drink it is only about 1/3 full. When Gideon drinks it in the next shot it is almost full.
Continuity mistake: In the scene just before the final attack on the castle, D'Artangan is surrounded by his fellow Musketeers. He gets off his horse and while doing so there is a tight close up where you see clearly that he is wearing his Musketeer outfit that he threw down on the floor in the previous scene. When he finishes talking to the horse (and he is back in his normal clothes) Porthos hands him the Musketeer uniform, which D'Artangan then puts on. (01:20:45)
Continuity mistake: In the early-morning scene at Mr. Brownlow's house, Oliver is shown sleeping in his bed. He awakens and his hair is in complete disarray as he walks towards the open balcony doors. Standing on the balcony and gazing outside, however, his hair is combed neatly.
Continuity mistake: During the paper cut scene, when Bella is thrown against the table, there are 5 vases of flowers and 3 sets of candles. After she hits the table she lands against one of the vases and knocks the 2nd one to the floor, but the next shot shows only one vase left upright. (00:14:50)
Continuity mistake: At the "Big Pipe" contest the star gets trapped under water when her leash gets caught on some rocks. You see her undo the velcro on her ankle and then abandon the board (with the leash attached). About 20 seconds later when she is diving below the oncoming waves you can clearly see the leash re-attached to her ankle.
Revealing mistake: Most of the posed, fake displays in the ape's Museum of Natural History contain real people who are slightly moving if one pays careful attention. Especially noticeable are those posing with objects held in - or above - their hands.
Character mistake: During the movie's opening credits, Sara is shown auditioning for Juilliard, which is misspelled as "Julliard" on a sign outside the room where the audition is occurring.
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: After Harry Zidler first sees Christian and Satine kissing, when they stop kissing, Satine's lipstick switches from being smeared to perfectly done and bright red when she walks and when Zidler is talking to her about having to end the infatuation.
Other mistake: In the scene where Madonna is pouring candle wax on Defoe, once they start having sex (with Madonna on top), you can clearly see Defoe's manhood poking out where it shouldn't. I realise they're not actually having sex, but shouldn't it be taped up out of sight?
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.
Tiana broke the talisman that the voodoo man had, thus breaking any more frog-turning spell. I know Mama Odie said that Naveen and Tiana broke the spell when they got married, but Dr. Facilier was still responsible for the spell in the first place, and he died, so there's that.
Factual error: All the Cisco VoIP phones seen in the film have the booting Cisco logo on them and would not work due to no connection.
Other mistake: When the two Americans are walking on the moors, their shadows are always in front of them, despite them having changed direction numerous times. Additionally, with the moon always being behind them, how are their faces being lit?
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)
Plot hole: Dafoe and Bullock leave the ship a long time before it hits the tanker and there is a lot more time before it crashes into the town and even more before Alex gets on that speedboat. No matter how fast he could have gone, there is no way he would have caught up with them.
Other mistake: When Christian and Ana are discussing his birthday, you can see Christmas decorations in a window they pass, indicating that his birthday is somewhere around that time. However, his birthday is in June.
