The All of the teachers from the books made their way onto the big screen, ranging from the loathsome Dolores Umbridge to the nice Remus Lupin. Sometimes, lessons in the subject would make for some moving and amusing scenes, helping shape the wizarding world as it is today.

Yet while viewers got glimpses into what the topic was like, fans didn't always get the full picture. So here are 10 moments from the books that were omitted from the movies, depriving people of some brilliant content as a result.

Quirrell's Bad Lesson

Professor Quirrell first meets Harry in Diagon Alley, cutting a nervous and scared figure as he talks to the Boy Who Lived. This prompts Rubeus Hagrid into explaining how he changed after an encounter with a hag, which is pretty understandable. However, as anyone would expect, his lessons are far from great as a consequence of his anxious behavior.

In The Sorcerer's Stone, Quirrell struggles to captivate his class. He speaks about his turban, the weather, and fighting off a zombie before then falling silent when his students ask to learn more. In a twist, it's then later revealed he's working on behalf of Lord Voldemort.

Talking About The Stone

Fantastic Beasts Nicolas Flamel

Given Quirrell didn't exactly ooze authority, pupils would take to talking in his class. And, during one of his lessons in the first book, Harry and Ron talk about what they'd with a Sorcerer's Stone if they had one.

The novel doesn't delve too much into this, but it would have been intriguing to know what they'd say. While the stone has its advantages, living for hundreds of years wouldn't exactly be fun. It's a wonder Nicolas Flamel kept going for as long as he did.

Lockhart's Quiz

As fans of The Chamber of Secrets movie will know, Gilderoy Lockhart is pretty full of himself. And he goes one step further in the book, giving students a quiz on himself - with questions ranging from what is his favorite color to when his birthday is. Most students are pretty horrified by this but Hermione Granger, as ever, tops the class by getting full marks.

This would definitely have been hilarious to see, and it's actually included on the deleted scenes of the VHS, DVD, and Blu-Ray releases. Lockhart doesn't appear in another movie after the 2002 title - despite popping up in The Order of the Phoenix book. There, he's at St Mungo's as he continues to recover from losing his memory.

Lupin And The Homework

The Prisoner of Azkaban film contains a scene where Severus Snape sets the class homework, much to their annoyance. It's particularly cruel because he doesn't even teach Defence Against the Dark Arts. The movie quickly moves on after this but, in the book, it actually has consequences.

Lupin gets them out of doing the homework, pleasing the class after they protested. Snape was likely far from happy about this, with Hermione then using the task to discover the truth about Remus being a werewolf - a secret he'd have preferred to keep under wraps.

Lupin's Obstacle Course

Out of all of Harry's Defence Against the Dark Arts teachers, Lupin may just be the very best. Coming after Quirrell and Lockhart, he proved to be a big hit among students due to his hands-on and imaginative style of teaching. And, in the source material, their third year ends with them having to battle their way through a difficult obstacle course.

Students had to wade their way through a paddling pool containing a Grindylow, cross pot-holes filled with Red Caps, avoid being tricked by a Hinkypunk, and overcome a Boggart. Harry comes through unscathed but Hermione, uncharacteristically, has some trouble with a Boggart. Hilariously, her biggest fear seems to be failing Professor McGonagall.

The Imperius Curse

The the Death Eater takes things further in the book of the same name, placing it on his students to see how they'd react.

Harry is quite shocked at the sights of Neville Longbottom performing gymnastics, Dean Thomas singing the National Anthem, and Lavender Brown impersonating a squirrel. After multiple attempts he's able to shrug off the curse, doing something fully-fledged wizards and witches would find difficult.

Dean Defends Lupin

Dolores Umbridge's snarky speech at her Defence Against the Dark Arts class is shown brilliantly in the film version of the Order of the Phoenix story. But it isn't entirely accurate, with multiple students other than Harry taking an issue with her words. Take Dean Thomas, for example.

When Umbridge aims a dig at Lupin by saying their previous teachers always hadn't been satisfactory enough for the Ministry of Magic's liking, Dean speaks out. He's about to say the werewolf was the best they've ever had when he's cut off. It speaks volumes about Lupin, showing just how popular he was. Unfortunately, that makes his death later in the series even more heartbreaking.

No McGonagall Punishment

McGonagall Umbridge Order Phoenix

In the fifth movie, Umbridge's argument with Harry over Cedric Diggory's death and Lord Voldemort's return ends rather abruptly. Imelda Staunton's character tells the Boy Who Lived to see her in his office and, soon afterward, that's exactly what happens. However, the book has Umbridge send Harry to McGonagall instead.

Harry enters her office fearing the worst, but things don't exactly play out that way. She warns him to be careful, urging him to keep his temper in check. With Umbridge being the nasty piece of work she is, this is definitely easier said than done. And while McGonagall is ive, she stops short of trying to get Harry out of his detention.

Snape And Nonverbal Spells

Fans of the Potter movies could be forgiven for wondering about nonverbal spells. Some characters in the series can perform magic without opening their mouth, while others need to speak the incantation out loud. And this is something Severus Snape educates students on during the Half-Blood Prince book.

Snape decides to put Harry to the test and the Boy Who Lived reacts quickly, performing a Shield Charm that sends his teacher flying. After responding sarcastically to his enemy, Harry then also lands himself in detention - having told Snape not to call him 'Sir'. This would have added comic relief to a movie that's lacking in that department.

The Inferi

The Inferi only appear in the Half-Blood Prince film towards the end, when Albus Dumbledore and Harry travel to an old cave to retrieve one of Voldemort's Horcruxes. But fans are given an explanation far sooner in the original version of the story.

Snape opens up about the Inferi during a class, telling students of how Voldemort used them during his first reign of terror. Alan Rickman's character also delves deep into their creation, revealing they're animated corpses brought to life. This, potentially, wasn't included because it was too dark.
