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)
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.
Continuity mistake: In the dormitory, when lovestruck Ron is going gaga over Romilda, he is wearing a brown sleeveless tee shirt and its tan trim has many holes. When Harry brings Ron to Slughorn, Ron is still wearing that tee shirt, but now some of the holes are gone and the rest of the holes have changed position. (01:26:50)
Continuity mistake: After Mike and Ned fight with lightsabers, when they are in the kitchen Mike's wedding ring moves from his left hand to his right hand and back again, depending on the angle of the shot. (00:21:05)
Continuity mistake: During the sequence where Margaret proposes to Andrew on the street in New York, the same woman in a green sweater walks by three times.
Character mistake: About 3/4 of the way through the movie, when Jennifer Aniston is talking to Ben Affleck, she calls him Ben instead of his character's name Neil.
Continuity mistake: When Ian films the Chipettes during the sing-off, he says, "If you like what you see then call Ian Hawke." But when someone else plays the video back later, he says, "If you're interested, then call Ian Hawke."
Visible crew/equipment: When Emma goes to crash Liv's wedding ceremony, as she crashes through the glass doors you can see film crew reflected in the glass panes.
Continuity mistake: When the reporter is interviewing Bad Blake in his hotel room he is using his pocketknife to cut the meat in his meal. When the shot returns to him, he is using a plastic knife.
Continuity mistake: When Jane is crying and staring at the sky she is not holding a napkin, as the scene cuts back she is.
Continuity mistake: In the carnivorous plant scene, Manny grabs the fruit (the bait), which is sitting in the middle of the plant. In the next few shots, the bait disappears and then is replaced with a bulb that housed the red and blue "wires".
Factual error: After James leaves the bar and is driving, you see a dealership in the background and you can see new trucks and a new model yellow mustang. The movie takes place in 1987, so the vehicles are about 20 years too new. (01:26:00)
Character mistake: Just after the birth of Mona's child, Farhan recollects "uss waqt agar Virus kehta kay mera pouta engineer.". In fact the child is not his "pouta" but his "nata"
Other mistake: At Paul's wedding, Paul gives a speech saying that Connor was always there for him, "ever since our parents died when I was 2 and Connor was 7". However, in the scene showing when Connor and Jenny were just kids and she gives him a camera for his birthday, Jenny and Connor appear to be at least 10 years old - certainly not 7. Connor tells his ghost, "that was the summer before my parents died". The scene that follows shows the parents funeral, with Paul sitting next to Connor, and Paul appears to be about 5 or 6 years old - but much older than 2.
Visible crew/equipment: The crew is reflected on the motorcycle-cop helmet when Mark says "He is not drunk".
Other mistake: Bowling score for Aram shows a 65 in the 4th frame. A strike would add 20 points to his score, which should be a 66 in the 4th. (01:01:37)
Continuity mistake: Claire sits on a blanket and empties a bag of stuff on it. Then it seems empty when she takes it from the ground to hand it over to Henry. The stuff would have sounded and the blanket is to light when she takes it from the ground to hand it over to Henry.
Continuity mistake: People are often shown listening to the radio at completely different times of day to the times shown on the boat.
Continuity mistake: When Rebecca is trying to get her papers out of her bag, Luke holds his hand out for her to hand them to him. The shot changes as Rebecca turns around, and suddenly Luke isn't holding out his hand anymore.
Other mistake: When Abby and Mike are making out in the elevator, the elevator door opens up to what seems like a board and then the shot goes back to them and back to the open elevator door with scenery outside the elevator.
