Continuity: There are two scenes during which Harry is shown having visions of the Dept of Mysteries while he is asleep. The first scene occurs after Harry's confrontation with Seamus in the Gryffindor common room. There are shots of Harry lying in bed wearing a short sleeve, crew neck tee shirt, but when he is startled awake by the vision of Voldemort, he sits up wearing a buttoned henley tee. The next day is the first day of DADA class with Umbridge. That last shot of Harry in the henley tee shirt was cut from a later scene. Later in the film, when Harry has the vision of Arthur Weasley's attack, he is wearing the henley tee shirt.

Revealing: In the Forbidden Forest, HRH are introduced to Grawp. Just as the giant lifts Hermione off the ground, in the shot from behind her, Hermione's legs disappear below her calves; the digital lines are actually visible. Slow-mo is not necessary. (Only visible on fullscreen DVD.)

Continuity: As Harry holds the Prophecy, when Lucius says, "Don't you want to know the secret to your scar? ...I can show you everything," both he and Bellatrix stand directly in front of Harry and neither are wearing masks. The problem is in the overhead shot, when Harry says, "I've waited 14 years," two mask-wearing Death Eaters are approaching Harry, who's holding the glowing Prophecy orb, but maskless Lucius and Bellatrix are supposed to be standing there already.

Continuity: When Harry shouts, "Expecto Patronum," he points his wand at 'his' Dementor as the Patronus repels it and it flees. Harry then stands and puts his wand arm down, but in the next shot his wand is still up, pointing to his right with the Patronus in mid-air.

Other: When Dumbledore is dueling with Voldemort in the Ministry Atrium, there is a close-up shot of Voldemort as he opens his mouth wide, laughing. The filling in the Dark Lord's upper molar is visible in his newly acquired body.
