Question: How do the Death Eaters escape from Azkaban when it is very tall where the explosion happened/spell hit, and they don't (or shouldn't) have their wands?
Question: How is it possible that Harry has no problems with trusting Alastor Moody in this movie? At the end of the previous movie, he discovered that "Moody" was an evil imposter who conspired against him. He only saw the real Moody briefly when he was trapped inside his trunk and didn't even interact with him. So how come he isn't distrustful/suspicious towards him if he barely knows him?
Answer: How can Harry trust anyone, knowing they could be a Polyjuice imposter? The rest of The Order of the Phoenix trust Moody, and that has to be enough for Harry.
But in the book, he remembers that "Moody" was fake.
And was caught and replaced with the real Moody.
Still, it would have made much more sense if Harry said, "Professor Moody? Is that really you?" and Moody replied, "Yes, it's really me, the real Alastor Moody, not this cheap imposter."
Answer: Agree with the other answer, but would add that any evil wizard attempting to gain proximity to Harry by using Polyjuice potion would be unlikely to impersonate "Mad-Eye" Moody, as the real one would now be closely scrutinized and vetted by the Order.
But there is another issue. Harry acts as if he knew Moody very well, despite never interacting with him before.
As mentioned, Harry was present when the real Moody was rescued at the end of "Goblet of Fire." He likely had interaction with him immediately following that event and then later, even though it's not shown on screen. He also knows Moody by his colourful reputation and that Dumbledore and the Order of the Phoenix fully trust him.
He didn't interact with Moody in the previous movie because Moody was in a bad mental state due to being trapped for a whole year. It took Moody some time to recover from this trauma.
Answer: And why shouldn't Harry trust Moody? He was a loyal member of the Order Of The Phoenix. Barty Crouch Jr., who impersonated Moody, was sent back to Azkaban. And even though Harry hardly knows him, he knows well enough that Moody is there to help him.
Question: While at the park, why did Dudley still bully Harry? Knowing that Harry is quite capable of doing magic, wouldn't it have been better for Dudley to just leave him alone instead of trying to act macho in front of his friends?
Answer: Dudley was too much an immature bully to stop harassing Harry. His entire personality was selfish, boorish, and cruel. He knew exactly what he could and couldn't get away with regarding Harry. He also knew Harry was not allowed to perform magic outside of Hogwarts while underage and would get into severe trouble for harming a Muggle. The entire Dursley family increasingly feared Harry as he matured. Dudley started to change for the better after Harry saved him from the Dementors.
Adding on to this answer: In the "Chamber of Secrets" book, some of this is explained. Chapter 2 is when the Dursleys learn that Harry is *not* supposed to be using magic outside of school. Until then, he briefly enjoys their nervousness around him.
Factual error: After returning to the Dursley's after the dementor attack It is dark, this shows again when Vernon puts Dudley in the car. However, the howler from Mathila Hopkirk says that at 6:23pm Harry performed illegal magic. As the side story shows it is a hot summer, it wouldn't get dark until way past 8pm. (00:04:53 - 00:07:20)
Suggested correction: Fairly certain the film was clear that the reason it got dark was because of the dementors, they have the ability to change the weather to depressive darkness.
Corrected entry: During the scenes where "Dumbledore's Army" are practicing their spells, at one point they are using the spell 'Levi Corpus'. It is not until the next book (The Half Blood Prince) that this spell is actually discovered and used.
Correction: James Potter used it on Snape at school and the death eaters used it on the muggle campsite owner at the quidditch World Cup. Both of these events happened before this film, meaning its not beyond probability that they would know it.
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.
Correction: Neville never says that. He calls to Harry and says "It's got your name on it". Later, Lucius Malfoy tells Harry that only the person whom the prophecy is about can retrieve it, meaning retrieve the prophecy from the ball. Anyone can touch the ball. You'll notice the prophecy isn't spoken from the ball until Harry holds it.
But why does Lucius Malfoy want it if he can't listen to it?
Lucius was ordered by Voldemort to bring it to him. Voldemort can listen to it just like Harry can. It involves both of them.
Question: Why did Harry and Ron get into so much trouble for using the flying car in "Chamber of Secrets", but in this movie/book, the Order of the Phoenix members openly fly on broomsticks?
Answer: Ron and Harry, who were under-aged, took the car without permission, flew it haphazardly, nearly got Harry killed, were seen by Muggles and it was reported in the Muggle news. They also crashed the car into the Whomping Willow, causing much damage and could have injured others at Hogwarts. Their actions also got Mr. Weasley into trouble with the Ministry of Magic, because Mr. Weasley bewitched a muggle object which is illegal by wizards' law. When the Order of the Phoenix is moving Harry to a safe house, it was carefully planned and precautions were taken to avoid being seen, much like how the Knight Bus is always undetectable to Muggles.
They flew next to a ferry which would also be a bad idea.
Even though it's illegal to bewitch a muggle object, several wizards have enchanted cars. The ministry of magic owns several enchanted cars. Think about the Knight bus, not illegal. So Mr. Weasley was not in trouble for that.
Question: Hermione couldn't understand why Ron wouldn't wear what his mother made him for Christmas but I am curious, was Hermione wearing what Mrs Weasley made for her when they were walking down the stairs?
Then why would she not get why Ron isn't wearing it when she isn't wearing her own gift from Mrs Weasley?
Ron has a long history of being embarrassed by his mother's rather odd homemade gifts. Unlike Hermione, because his family was poor, he had few options on what else he could wear. Hermione, being a guest, would not be expected to wear her gift at any particular time. She also thinks Ron is over-reacting.
Corrected entry: In one scene in the common room the song 'Boys Will Be Boys' by 'The Ordinary Boys' is playing, released in 2006, but this film is set in the 1990s, before the song was released.
Correction: The films are separate from the books - the films have never stated what year they're set.
As far as I know, the movies don't explicitly state their years, but the years can be inferred but are a mess. For example, the graves for the Potters say they died in 1981, so if Harry was one year old when they died, it was about 1991 when the first movie starts. This date match the book's dates. It does raise a problem with the 7th movie though, since we see the Millennium Bridge collapse, which wasn't opened until 2000, and the Dursleys driving a 2008 model car. I think the producers didn't say a date so didn't worry much about consistency.
Movies are separate from the books but they are set in the same time as them.
Nope. For a start we see the Millennium Bridge in the movies, which wasn't opened until 2000.
The millennium bridge being in the movie is actually a mistake, as its supposed to be 1996. I think its listed.
Question: Why would Harry say Voldemort killed Cedric? Obviously it was Wormtail.
Answer: Peter Pettigrew was believed to be dead by the entire wizarding world. The only witnesses are Lupin (a werewolf), Sirius, who is still on the run, Harry, Ron and Hermione. No one believed him about Voldemort returning, as they thought he was only seeking attention. Its safe to assume everyone would also think the same about Pettigrew being alive.
Answer: Quite simply, someone else caused the explosion from the outside. Or for that matter, seeing how the Dementors have changed sides, it is not unlikely that someone was allowed to come in to Azkaban and break the Death Eaters out.
Twotall
I think that Voldemort was the one who caused an explosion from the outside.
