Corrected entry: In the Hall of Prophecy, when Neville spots Harry's glass orb and says, "It has your name on it," he is looking up at the fourth shelf, above his head. In the next shot of Harry he is looking up as well, but in his next close-up, the orb is now on the third shelf, and Harry (who is at least a foot shorter than Neville) is actually face-to-face with it, before he ever touches it.

Corrected entry: While Harry is fighting with Sirius against the two Death Eaters, he just all of a sudden knows how to use non-verbal spells.
Corrected entry: In the very last scene where the camera pans out, we can see the Hogwarts Express. As the camera moves upscreen, we see that the tracks suddenly vanish under the trees. This is obviously merely tree cover, but we next see the lake, with no tracks going over or around it. In the scene where they are travelling to Hogwarts, as well as in similar scenes in most previous movies, it is shown that the Hogwarts Express travels over a causeway by the side of the lake before arriving at Hogwarts Station.
Corrected entry: The playground where Harry is during the first few scenes is located in a rural setting, separated from the nearby subdivision by a highway and an underground pedestrian walkway. However, when Harry first sees Sirius (in grim form) and the Knight Bus an the beginning of "Prisoner of Askaban," the exact same park is surrounded on three sides by houses. Though it is possible that contractors built the two identical playgrounds, it does not make sense why Harry and Dudley & co. would go all the way there when the other one is closer and doesn't involve leaving the neighbourhood.
Corrected entry: When Harry enters his room at the Dursley's after being expelled, this is the first time he's been in there since before the dementor attack, during which he used his wand. However, his wand is already lying on his bedside table when he enters the room although he should be carrying it on him.
Corrected entry: In the Ministry of Magic near the end, Neville tells Harry that he couldn't pick up the prophecy ball because it had Harry's name on it and only the person whose name is on a prophecy may remove it. But a few moments later Hermione is able to use her wand to make numerous prophecy balls fly off the shelves in order to escape the Death Eaters.
Corrected entry: During the first DADA lesson Padma and Parvati Patil make a flying piece of paper, and it is clear that they are in the second row sitting behind two other people. Near the end of the scene it shows the two of them in the front row.
Corrected entry: When Luna just entered the Room of Requirement, and Filch, Malfoy, Crabbe, and Goyle are running after her. The members of the Dumbledore's Army are standing around the dummy practicing on it. It is extremely clear that Neville says expelliarmus, and succeeds, but no one applauds him (this is before he disarms Parvati.).
Corrected entry: In the Department of Mysteries, when each Death Eater has their wand aimed at a member of Dumbledore's Army, Lucius Malfoy walks towards Harry. Jason Issacs, who plays Malfoy, has brown hair, and in one shot you can see his real hair under the blonde wig.
Corrected entry: At the Hogshead's Inn, when the students are meeting with Harry to determine if they want him to train them, they begin naming some of his accomplishments. Nevill makes mention that Harry killed a basilisk in Dumbledores office, when, in fact, Harry killed the basilisk in the Chamber of Secrets, not Dumbledores office.SAZOO1975
Corrected entry: In the scene just before Harry and Cho kiss in the Room of Requirement, there is a clear Daily Prophet headline to the right of the mirror - 'Mystery Disappearences' a mis-spelling of the word disappearances.
Corrected entry: In the beginning of the movie, the radio announces the upcoming temperature in Fahrenheit. In Britain celcius would be more likely.
Corrected entry: When Lord Voldemort holds out his hand to receive the "prophecy-bubble" he is forcing Harry to give to him, we see a shot of Neville shouting "Don't give it to her!" Her? You-Know-Who isn't exactly a very masculine type, but... (There was probably a scene with Bellatrix there which was cut out.)
Corrected entry: When Harry is having a dinner with the Order of Phoenix group, look at the glasses - the liquid inside differs from empty to full from shot-to-shot.
