Visible crew/equipment: During the Quidditch match Harry's broomstick tries to shake him off, due to the spell. After Hermione tells Ron, "Leave it to me," in Harry's last close-up before he flips over, the seat that is attached to the broomstick, to make it more comfortable for Dan Radcliffe to sit on, is entirely visible. Glimpses of other seats can be had during the match as well.
Continuity mistake: When the troll enters the girls' lavatory, in the wide shot as Hermione walks backwards towards the cubicles, the room becomes brighter from the storm. With this extra bright light it is simple to see that the wall between the 2nd & 3rd cubicles actually touches the floor, unlike the other cubicle walls. Yet, in the overhead shot as the troll's club slams into the cubicles, Hermione is lying under that very wall crawling away. Impossible!
Continuity mistake: At the snake exhibit, while Harry speaks with the Python the snake's body lies curled over a long wood log and a large rock. In the shot from outside the Python's exhibit, after the glass pane disappears Dudley falls over the rail and the snake is gone, not positioned differently, but altogether gone! In the next overhead shot inside the Python's exhibit, while Dudley falls the snake is back lying on the log and rock, in the same position as in the previous shots.
Question: I get that the DADA role is cursed because of Voldemort being denied the role when he applied for it at Hogwarts, but why does Dumbledore not let Snape take the role like he's wanted to every year? I thought Snape was a double agent (he spies on the Death Eaters and Voldemort for Dumbledore, and he pretends to be on Voldemort's side too), so unless Voldemort decides that he wants to get rid of him for being in the role, he's okay to take it on provided he's given it, and yet every year, Dumbledore turns down his application. Is it because Snape's too involved in Voldemort's side of things or some other reason? I hope I explained it well.Heather Benton
Question: What ever made Snape suspicious of Quirrell? He couldn't have known that Voldemort was attached to Quirrell, or even that Quirrell supported Voldemort, because he surely would have reported either detail to Dumbledore. Then Dumbledore would have stopped Quirrell. So it isn't clear why he guessed, correctly, that Quirrell let the troll into the school or tried to kill Harry during the Quidditch game.
