1. Seamus Finnegan
   Neville Longbottom
2. Lee Jordan
   Parvati Patil

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.

1. The guest room
   Dudley's second room
2. The parlor
   The garage

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.

1. Professor Dumbledore and Professor McGonagall
   Pansy, Minerva and Madam Hooch
2. Seamus, Lee and Pansy
   Malfoy, Crabbe and Goyle

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.

1. Peeves
   Sheeves
2. Neeves
   Heaves

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.

1. No meals for a week in the movie; no reading for a month in the book
   No TV time for a year in the movie; no meals for a week in the book
2. Scrubbing pots and pans for a century in the book; no meals for a week in the movie
   No meals for a week in the movie; in the cupboard until Christmas in the book

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.

1. Hagrid
   Malfoy
2. Ron
   Sirius

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.

1. Drive around aimlessly all day
   Pick up Aunt Marge
2. Drop Dudley off at a friend's house
   Ask Mrs. Figg to take Harry

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.

1. Dances
   Flies over the students
2. Eats the feast
   Sings a song

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.

1. He is the keeper of keys and grounds at Hogwarts.
   He's half giant.
2. He was expelled from Hogwarts.
   He doesn't have magical abilities.

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.

1. He bends it upward in the film, and there is no rifle in the book.
   He ties it in a knot in the film, and there is no rifle in the book.
2. He ties it in a knot in the film, and he throws it away in the book.
   He bends it upward in the film and ties it in a knot in the book.

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.

1. In the book, Hermione knocks him over; in the movie, he is knocked over when Snape is on fire.
   In the book, Hermione stands in front of him; in the movie, Snape falls on him.
2. In the book, he looks at Snape's robes; in the movie, Hermione knocks him over.
   In the book, Dumbledore catches him; in the movie, Hermione catches him.

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.

1. Seamus in the book and Hermione in the movie
   Fred in the book and George in the movie
2. Neville in the book and Hermione in the movie
   Neville in the book and George in the movie

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.

1. Vernon Dursley in the book, Hagrid in the movie
   Hagrid in the book, Dudley Dursley in the movie
2. Hagrid in the book, Hagrid in the movie
   Hagrid in the book, Vernon Dursley 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.

1. Ollivander's friend
   The "History of Magic" book
2. Hagrid's favorite pet
   A Quidditch team

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.

1. Vernon Dursley
   Marge Dursley
2. Piers Polkiss
   Petunia Potter

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.

1. The Bloody Baron
   Nearly Headless Nick
2. Moaning Myrtle
   Rowina Ravenclaw

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.

1. Harry is allowed to ask three questions about his future.
   Firenze lets Harry touch the unicorn.
2. Harry rides Firenze.
   Firenze teaches Harry how to read the stars.

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.

1. He is secretly sent to Charlie.
   Dumbledore has him killed.
2. Hagrid sets him free.
   Hagrid gives him back.

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.

1. "A History of Magic"
   "Quidditch Through the Ages"
2. "Nicholas Flamel's Alchemy Sessions"
   "Care of Magical Creatures"

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.

1. Push the losing piece off the board
   Throw each other off the board
2. Erase each other off the board
   Knock the losing piece down and drag it off the board

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.

1. Marcus and Firenze
   Fritz and Lockshmy
2. Lockhart and Bane
   Ronan and Bane

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.

1. In the book, he leaves it by the astronomy tower. He doesn't lose it in the movie.
   He doesn't lose it in the movie or the book.
2. In the book, Malfoy steals it. In the movie, Filch confiscates it.
   In the book and the movie, Malfoy steals it.

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."

1. A large book
   The back of Dumbledore's chocolate frog card
2. From Fred and George Weasley
   Neville figures it out first.

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.

1. Cornish pixies
   Dumbledore's gems
2. Transfiguring cats
   Bottles of potion

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.

1. Mrs. Figg's cat died.
   Mrs. Figg broke her leg.
2. Dumbledore made the Dursleys take Harry.
   Dudley demanded that Harry go.

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).

1. Where Harry wakes up
   How Quirrell dies
2. What happens to Snape
   Who wins the House Cup

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.

1. Pressing his face
   He's passed out.
2. Laughing
   Calling for Dumbledore

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).

1. Harp
   Flute
2. Nothing
   Violin

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.

1. His parents and grandparents in the novel and just his parents in the movie
   His parents and Nicholas Flamel in the novel and just his parents in the movie
2. His parents and uncle in the novel and just his parents in the movie
   Just his parents in both the novel and the movie

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.

1. Five in the book, three in the movie
   One in the book, one in the movie
2. Three in the book, one in the movie
   One in the book, three in the movie

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.

1. Harry, Hermione, Draco and Seamus
   Harry, Hermione, Draco and Neville
2. Harry, Ron, Hermione and Neville
   Harry, Ron, Draco and Neville

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.

1. In the book and the movie, Harry gets the photo album at the train.
   In the book and the movie, Harry gets the photo album while in the hospital.
2. Hagrid never gives the photos to him in the book, but Harry gets them at the train in the movie.
   In the book, Harry gets the photo album in the hospital wing. In the movie, Harry gets the photos at the train.

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.

1. Magicked ropes in the book and magicked fire in the movie
   Magicked fire in both the book and the movie
2. Magicked ropes in both the book and the movie
   The Cruciatus Curse in the book and magicked fire in the movie

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.

1. From an Irish feller in the movie and from a Greek chappie in the book
   From a Greek chappie in the movie and from an Irish feller in the book
2. From a tradesman in the book and from a poker player in the movie
   From a Frenchman in the book and from an Irish feller in the movie

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.

1. One month
   One year
2. Harry doesn't return to the Dursleys' house.
   Three days

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.

1. In the hospital wing in both the book and the movie
   In Dumbledore's office in the book and on the stairs in the movie
2. In the hospital wing in the book and at the stairs in the movie
   In the dorms in the book and in the hospital wing in the movie

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.

1. Diagon Alley
   The Leaky Cauldron
2. Platform 9 3/4
   The Hogwarts Express

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.

1. Albus Dumbledore
   Professor McGonagall (as a cat)
2. Vernon Dursley
   Dudley Dursley

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.

1. Professor Snape
   Professor Sprout
2. Peeves
   Whoever robbed the vault

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.

1. It's spelled "Nicolas Flammel" in the book and "Nicholas Flamel" in the movie.
   It's spelled "Nicolas Flamel" in both.
2. It's spelled "Nicholas Flamel" in the movie and "Nicolas Flamel" in the book.
   It's spelled "Nicholas Flamel" in both.

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.
