Harry Potter and the Sorcerer's Stone — Film vs. Book Quiz

In the book, Neville Longbottom is actually a close part of the gang that includes Harry, Ron and Hermione. He does some pretty important stuff to help his friends along the way. However, many of these scenes aren't in the movies, and Neville's actions are given to other characters.

In the book, Dudley has two rooms. One of those rooms holds all of his toys. The Dursleys realize that they should allow Harry to move into a proper bedroom because someone might be watching them.

The scene before sorting, when Draco Malfoy tells Harry there are right wizards and wrong wizards, actually takes place on the train in the book. A fight even breaks out between the two groups of boys.

Peeves repeats himself, is loud and is constantly making terrible sounds and noises. He also likes to get the children in trouble. Scenes with Peeves were shot for the first film, but he never made it to the final cut.

Throughout the book and the movie, we see Vernon Dursley deliver quite a few punishments to Harry. Harry's reactions to these punishments develop his character and show how he responds to the Dursleys in general.

In the movie, Hagrid runs off to buy Harry a birthday present — Hedwig the owl — while Harry tests out his first wand. This gives Harry the opportunity to learn a little more about the wizarding world from Ollivander, rather than from Hagrid.

The scenes where Vernon Dursley gets frustrated and goes a little crazy about the invitations to Hogwarts were cut down in the movie. While the book spends the better part of a chapter showing his slump into madness, the movie explains it more quickly with visuals.

In the books, the Sorting Hat sings a song each year before sorting. The lyrics to these songs recap the previous year, and they actually give readers a little foreshadowing. However, these songs aren't heard in the movies.

We learn in the second movie, "Harry Potter and the Chamber of Secrets" (2002), that Hagrid was expelled from Hogwarts. Readers learn in the first book that he is not allowed to do magic, and we learn why.

In the movie, Vernon pulls the trigger on the rifle, and the gun shoots up, toward the ceiling. However, in the book, Hagrid simply ties the rifle in a knot, making it completely useless.

If you rewatch the movie and you look in the background during this scene, you can see Quirrell sitting behind Snape with his hand over his mouth. When Snape's robes catch fire, Quirrell is knocked over — but not by Hermione.

Giving one movie character the job of two book characters helps reduce film time because less time is spent on character development. For this reason, we don't see Neville looking for his toad in the movie.

When you first watch the movie (especially if you haven't read the book), you may be a little confused as to why Hagrid simply leaves Harry stranded and wandering around looking for platform 9 3/4. But if you read the book, you realize that Vernon Dursley simply drops him off at the station and leaves him to wander around.

We learn in the book that Harry chooses Hedwig's name from his "History of Magic" book. However, in the movies, we don't hear Hedwig's name until the second installment.

Piers Polkiss is Dudley's friend who joins them at the zoo — in the book. The character doesn't make it into the movie, and the majority of his lines are either cut or given to Dudley.

Book readers know that the only entity who can really control Peeves is the Bloody Baron. For this reason, Harry impersonates him to help him and his gang get to the trap door without being noticed.

This scene in the book shows why Bane and Ronan are angry with Firenze. They don't like him meddling with humans in the first place, but allowing Harry to ride him made Firenze look like a common mule.

Hagrid loves dragons ... they are his favorite. However, as Norbert grows too big to handle, he must go live with his own kind. Of course, this breaks Hagrid's heart, showing the audience even more about his character.

Snape's character in the book is a bit darker than in the movie. This scene was cut from the movie because it simply leads to Harry learning about Snape's injury. In the movie, Harry sees Snape's injury immediately after defeating the troll.

Ron proves himself to be a strong strategist in Wizard's Chess in both the book and the movie. However, when he plays on a life-sized board, the stakes are higher for him and his friends.

In the Harry Potter series, centaurs don't much like humans, as humans treat centaurs rather badly. When Firenze saves Harry from Voldemort in the woods, Ronan and Bane get very upset with him, because centaurs should only be concerned with what is foretold.

Harry has a tendency to be a little forgetful, but whoever replaces the Cloak of Invisibility knows that Harry will need it again soon. Harry finds it on his bed with a note that says, "Just in case."

In the book, Harry first learns about Nicolas Flamel when he reads the back of Dumbledore's chocolate frog card. In the movie, the friends learn about Flamel from a book. Chocolate frog cards are more fun.

There is an additional obstacle set up to guard the Sorcerer's Stone. Snape has seven bottles of potion on a table. One bottle kills, another would send them back and a third would help them advance. Other bottles hold nettle wine. In the book, Hermione figures this one out.

If you only watch the movies, you will not see Mrs. Figg until the fifth installment, when she retrieves Harry after a Dementor attack. However, readers see her speckled throughout the book, and Harry describes her as a little weird (especially before he learns of the wizarding world).

In the book, Quirrell dies because Voldemort leaves his head. In the movie, however, Harry turns Quirrell to ash by touching him. This change in the ending helps portray Harry's powers over Voldemort.

Young Harry doesn't watch Quirrell die in the book. This actually resolves a major plot hole with the Thestrals in the fifth movie, as one would wonder why he couldn't see them sooner since he killed Quirrell (and watched him die).

Harry, Ron and Hermione learn that the only way to calm Fluffy down is with music. Though we see him snoozing to a magicked harp in the movie, the children bring a flute with them in the book.

It is important to remember that the Mirror of Erised gives us neither knowledge or truth. Harry's grandparents aren't mentioned in the movie, so they aren't represented in Harry's reflection either.

In the movie, each of the friends' skills is highlighted with a challenge — Harry's skill being his Quidditch ability. However, the book is a little more subtle with it, and there are multiple broomsticks in the room with the winged keys.

Although there are plenty of comic relief moments where we see Neville getting into trouble, there are plenty more in the book that help us understand his character better. Never forget the wacky broomstick and Neville's toad jumping in front of McGonagall.

While we see the album in both the book and the movie, it was delivered at different places. No matter where Harry receives the photos, it's an important moment between him and Hagrid.

Special effects in 2001 were a little different than they are now. The decision to make a wall of fire rather than magicked ropes was a budget issue, as pyrotechnics were cheaper than slithering ropes back then.

All Potterheads know that Hagrid is a lover of animals and he thinks he can train them all. Hagrid accidentally tells the kids and Quirrell that the easiest way to calm Fluffy down is to play some music.

In the book, Harry has to go back and live with the Dursleys for another month before school starts. When we see Harry return to the Dursley's, we learn how Dudley will get his tail removed in a rant from Uncle Vernon.

This minor change gives Dumbledore and Harry a little privacy in the movie, and it creates a bigger dramatic moment when Harry finally sees his friends again. Harry asks them how they're doing.

Draco Malfoy's distaste for Muggle-born witches and wizards attending Hogwarts is made clear in the first book. This is Harry's first experience with prejudice in the wizarding world.

The first chapter of the first book really has a lot of voice. We learn a little bit of background about the Dursley family, and (from Vernon's perspective) we see some oddly-dressed people hanging around. It turns out that they're witches and wizards who are happy about the death of Voldemort.

Because the poltergeist Peeves was omitted from the movie, Ron instead says that someone is playing a joke by letting the troll in. However, in the book, Ron blames the poltergeist, who is known for playing pranks.

This change in spelling is so minor that even the biggest Potterheads may have missed it, because the writing is only shown on screen for a moment. Small changes like this are commonly seen in movies adapted from novels.
