Super Grover

Revealing mistake: During the chess game the Queen attacks the Knight's horse that Ron sits upon. In this close-up just before the spear actually hits the side of the horse, the large hole, used to aid the stunt, is visible in the belly of the horse between the stirrups towards the hind legs. This hole is not in previous shots. (Visible in fullscreen DVD.) (02:05:10)

Revealing mistake: Just after Harry gets back on his broom, the Slytherine seeker chases the snitch and he passes towers of (in order) Gryffindor, Hufflepuff, Ravenclaw, Slytherine, Gryffindor and Hufflepuff, on his left (this means Hogwarts is also to his left), when Harry flies up beside him. However, next shot as Harry slams into him, they still fly in the same direction, and the school is now on their right. Mistake with the background plate. (01:22:00)

Revealing mistake: While Vernon kneels as he tosses Harry's Hogwarts letters into the fire, the interior solid back of the fireplace is visible behind the flames. On Sunday, the first letter (from the fireplace with a CG back) hits Vernon in the face as it flies by. In the following two shots of the fireplace, as more letters fly out, there are now large holes at the interior back of the fireplace that are visible. As the letters pour down from above, air is blown through these holes to blow the letters out and about. (00:10:20 - 00:11:20)

Revealing mistake: After being dropped by the troll in the girls' lavatory, Harry then scoots backwards on his backside and it is apparent that he is wearing knee pads under his pants. (01:11:40)

Super Grover ★

Revealing mistake: At the start of the overhead shot as the troll's club smashes the cubicles, while Hermione lies on the ground, the top beams of all the cubicle walls and the front door of the second cubicle are all visibly pre-broken before the club slams into them. (01:10:15)

Super Grover ★

Revealing mistake: When the mail comes, Ron receives the Daily Prophet and Harry asks, "Can I borrow this?" As Harry asks to borrow the newspaper, the Malfoy body double is plainly visible over Ron's left shoulder. (00:54:10)

Super Grover ★

Revealing mistake: During Madame Hooch's flying lesson, as Ron tries to get his broomstick to float up to his hand, Ron moves his head towards his right to be in perfect alignment with the handle of his broomstick, as it flies up to whack him in the head. (00:55:40)

Super Grover ★

Revealing mistake: At the zoo, Harry looks to his right, at the 'bred in captivity' sign of the Python. In this close-up, the green plant that is below, to the side of the exhibit sign, is protruding out past where the glass supposedly is, yet this is BEFORE the glass disappears. As a matter of fact, this plant, nearest the exhibit sign, changes its position considerably throughout these shots. (00:06:50)

Super Grover ★

Revealing mistake: After Madame Hooch takes Neville to the hospital wing, Malfoy takes the Remembrall and mounts his broomstick, on a convenient protruding metal rod. Then when he comes around, though the students step away and watch as he begins to fly off, many of their eyes are not level with Malfoy, as he is merely edited into the end of this shot. (00:57:50)

Super Grover ★

Revealing mistake: After Hagrid says, "Dry up, Dursley, you great prune," in the next shot just as Vernon fires the bent gun, before the hole actually appears, the light at the muzzle end illuminates the floor above and the outline of the pre-made hole is visible. (00:13:35)

Super Grover ★

Revealing mistake: While sitting on the couch in the hut on the rock, Hagrid asks, "Did you ever make anything happen, anything you couldn't explain? When you were angry or scared?" In the shot when he's getting up off the couch, it is blatantly apparent that the fingers on his left hand are latex in this shot. The hands are visibly artificial in other shots as well. (00:15:30)

Super Grover ★

Revealing mistake: In the shots facing Vernon, he holds the first Hogwarts letter while sitting at the table. Though in the close-up of the letter as he holds it, it is not Richard Griffiths' hand, that is shown with bitten up fingernails, holding the envelope. (00:09:15)
