Corrected entry: In the scene of the sea hut, how could the gun have been shot if Hagrid had bent it?
Corrected entry: When Hagrid picks up the Philosopher's Stone from Gringotts, he tells Harry "best not mention this to anyone". But as soon as Harry becomes suspicious about Snape, he begins discussing the fact that Hagrid emptied the vault in full earshot of all and sundry, at the dinner table.
Corrected entry: After the Quidditch Match Hagrid says something like 'That's strictly between Dumbledore and Nicolas Flamel.' When he finishes Harry says 'Nicolas Flamel?' Watch Ron. He is mouthing Harry's lines.
Corrected entry: In the scene in the Great Hall where Ron is looking at his Chocolate Frogs cards, Harry picks one up. It's suppose to be Dumbledore's card, but in several shots you see where Dumbledore's picture should be. Instead, all you see is the green screen attached to the cards.
Correction: Dumbledore's picture was a simple holographic foil image; the same kind you'd see on any credit card. There was no green screen effect needed for this. What you're seeing is just the way the light plays off the foil when viewed from an extreme angle.
Corrected entry: In the flying practice scene, after Malfoy gets hold of Neville's rememberall, he flies up with his broom and, after dialogue with Harry, he throws the globe away. Harry, after flying at least twenty metres after it, catches the globe in front of McGonagall's window, which is at least on the eighth floor of a tower. When Harry flies back to the others and lands, McGonagall almost instantly comes up behind him. Now wasn't that a bit too fast? She can't have apparated, as no-one can do that on Hogwarts grounds.
Correction: There are many secret passages in Hogwarts, and as a teacher McGonagall should know most ,if not all, of them.
Correction: Also, as a skilled teacher, she probably apparated.
The Hogwarts grounds are enchanted; no one can apparate onto or off them, not even a skilled teacher.
Correction: The gun is a shotgun. Since shot consists of small pellets they could have easily passed through the bend.
