Other mistake: In quite a few shots during the film, it is much too obvious that there are no lenses in Harry's glasses, whereas in previous and following shots the glasses have lenses. A couple of instances are: when Harry drinks the Felix Felicis and when Harry kneels beside Dumbledore, at the foot of the Astronomy Tower.
Other mistake: When Margaret and Andrew first walk into the Immigration Office there are a group of extras seated directly to the left of them, in two rows. One of them, a guy with glasses and long black hair, wearing a white shirt with patterns (back row, second from the wall, next to the guy in the light yellow shirt), briefly looks at the camera as Margaret and Andrew walk by.
Other mistake: When Buck tells about his fight with Rudy, he swings while saying "Back, forth" in front of the others. They are looking the wrong way. He is also swinging on nothing at all.
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.
Other mistake: When The Chipettes perform their audition for Ian Hawke they are standing on the Jett Records sign on the roof of the Jett Records building. In order for the sign to read correctly from the street, Ian and The Chipettes should have a backwards view of the lettering. In the movie the sign reads correctly from Ian and The Chipettes point of view, meaning that it is giving a backwards view to the street, ie. it is the wrong way round.
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)
Other mistake: Charlotte's dad buys a newspaper in the beginning of the film. The same two paragraphs about Prince Naveen are repeated all over the front page, including under the headline 'Annual Goosenhoper State Gumbo Faire Is Smashing Success.' (00:08:45)
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.
Other mistake: In Volterra when Edward has his shirt off, his face and neck are a different color than the rest of his skin.
Other mistake: In a scene toward the end of the film, there is a shot showing a calendar with the month March 1998. It shows Friday as being the 13th (reference to Philip Morris' birthday), but Saturday appears as the 15th. Did the actual month of March, 1998 not contain the 14th?
Other mistake: When the girls go meet Mrs St Claire and schedule their dates as they are leaving they tell the other bride walking in that there is 1 date left available in June at the Plaza. Mrs. St. Claire would've told that bride the last remaining date was June 6th. Therefore, if Angela messed up the bookings hen the other bride would've already thought her date was in June 6th, and then she would not have disagreed to changing the date, because she'd be changing it to the date she originally thought she had.
Other mistake: Shortly after the start of the movie, when Eric Bana's character reappears in the library and starts to put his clothes back on, his pants are already undone. If he had suddenly vanished from the library, then his pants should not be undone (unless, of course, he was up to no good just as he vanished).
Other mistake: When Mark and Greg exit the casino holding buckets of chips they won, Greg holds one of his buckets at an angle at which all chips should fall off. This is obviously a prop.
Other mistake: When Rebecca gets back to New York, the cab she's in drives past a couple of billboards, advertising Disney's "G-Force", and the upcoming Bruckheimer produced "Prince of Persia". The billboards were reflected in the window of the cab in perfectly clear focus and correctly as the eye would see, not backwards as they should be as a reflection. (00:53:05)
