• In the book dobby makes the bowl of pudding that was on top of the refrigerator, levitate and then drops it after harry says that he will go to hogwarts, it splatters everywhere. In the movie dobby makes a cake that was on the table levitate. Harry follows it and the cake drops on top of the lady that was sitting on the couch. The uncle and the aunt see everything.
• In the movie harry wakes up all of the sudden (it didn't seem that he was dreaming or anything) goes to the window and looks up at the sky then he sees the car were ron is, get closer. In the book harry wakes up from a bad dream and sees the twins already at the window.
• Another difference was that Professor Mcgonnagle told them about the chamber. in the book it was Proffesor Binns.
• Just after everyone finds out Harry is a Parselmouth, Harry tells Ron and Hermione that he once set a Python on his cousin when actually, he set a Boa Constrictor on his cousin.

• When harry turns up in knockturn alley he has to hide. Then he hears lucius and draco talking with the owner and that's were he first sees draco. In the movie harry sees draco for the first time at the book store.
• At the dueling club thingy, they totally missed details and the whole chamber scene was messed up
• In the movie the sword just appears in the sorting hat and Harry grabs it. He stabs the diary while he is still injured and after Ginny wakes up and tells Harry everything Fawkes comes and heals Harry.

• The movie shows Harry's detention with Lockhart, but not Ron's detention polishing the trophies while he is still coughing up slugs. In the book this was important because Ron remembered Tom Riddle's name from a cup he was polishing.

• The sorting hat has the same difference as in the first movie. In the book Harry puts it on and it talks just to him, inside his ear.
• In the book, when Harry is about to open the chamber of secrets he dosn't begin to talk in parseltongue right away. First it is english and Ron says it's english, then, when he concentrates harder, he speaks in parsel. In the movie, he speaks parsel right after discovering the snake on the sink.
• In the movie, they didn't show how they got the ingredients to make the Polyjuice potion. Whereas in the book, they stole some ingredients from Snape's office using the invisibility cloak.

• In the book...after Fawkes injures the basilisk's eyes, Tom Riddle tells the serpent he can "still smell him." In the movie...Tom instructs the serpent that he can still "hear him"...therefore leading to the scene int he movie of Harry throwing the rock in the tunnel to confuse the basilisk.
• In the movie Hermione explains to Hagrid and Harry what a "mud-blood" is. In the book..Ron tells them both, in between burping up slugs.
• In the movie, the Dursleys let Harry keep all of his magical items in his room, and when the Weasleys come to get him in the flying car, everything is thrown in. In the book, the Dursleys lock up all of his magic supplies in the cupboard and Fred/George have to go in and pick the lock to retrieve Harry's stuff.
• In Chamber of Secrets the book, at the end scene in Dumbledore's office where Dobby gives a hint to Harry that Lucious Malfoy gave Ginny the diary, he keeps punching himself, and when Harry figures it out, he starts twisting his ears. In the movie, he doesn't punish himself at all. He just sort of mumbles and cocks his head at Lucious.
• In the book, Harry stuffed his sock over the book, and Lucious took it off and threw it aside. In the movie, the sock is in the book, and Dobby finds it.

• Near the end of the book, in Lockhart's office when Lockhart is about to put a memory charm on Harry and Ron, Harry performs the expelliarmus spell on him to stop him. In the movie, Lockhart gives up the idea after turning around and seeing that both boys have their wands out and pointing at him.There are speaking changes in here too!
  
• There are several differences between the movie and book in the scene in Moaning Myrtle's bathroom, when Harry and Ron are trying to get Lockhart to go into the Chamber of secrets. These include speaking changes and blocking and movement changes.
  
• The whole scene where Lockhart lectures Harry outside his first herbology lesson is not in the movie. This is a disappointment as it is one of my favourite scenes!

• Two Lockhart lessons which were mentioned in the book were not in the movie.
  
• In the book, when the first attack is found, Lockhart offers his office to Dumbledore so he can examine the cat and while Dumbledore is doing so, Lockhart is showing off and making a big deal of why it was a pity he wasn't there at the time of the attack. In the movie many of these details are missed out!

• In the movie when harry, ron,hermione, and draco had to serve detention in the dark forest, neville wasn't with them like he was in the book, also in the movie they left out the night duel harry and draco were supposed to have, but draco never showed up.

Scenes from the film, not shown in book

• In the Film 2 hermione does magic in diagon alley when Harry has smashed his glasses.
• in the movie Lucius says Avada to begin his spell to kill harry, then dobby interrupts him and performs magic on him to make him "not hurt harry potter"
• As Harry and Ron are in the car to get to Hogwarts, the lose the train and just about get hit. However in the book, the didn't not lose the train and almost get hit.

Other types of differences

• In the movie Hermione runs towards Harry hugs him and is about to hug Ron but backs off and gives him a hand shake oh and all around the movie we see Ron getting worried about harmoine and defending her.
• They did NOT shoot the Death Day party or when they were at Rons and de- gnomed the garden!
• Professor Binns, the ghost professor, is missing from both movies.
• My biggest complaint (aside from the over-Hollywood-ized melodrama and pointless action sequences) is that, in one movie scene, Dumbledore makes a point of saying, "Help will always be given at Hogwarts to anyone who asks for it." Same line as in the book. Later in the movie, when Harry is in the chamber with Riddle, the Gryffindor sword just... appears... out of the sorting hat. Please. In the book, after Fawkes brings the hat to him, Harry puts it on and desperately asks, "Help me, please help me." He actually asks for help a few times in the book, but *never once* asks for help in the movie. (Becka)
• When Dobby dropped petunia cake
  1. it was on the refrigerator and it smashed on the floor
  2. the letter from the ministry saying that harry had done underaged magic didn't came which caused Mrs Maison to run out of the house screaming because it came by owl post.
  3. Mr Durley when he goes upstair to tell harry off for Dobby making too much noise he is meant to say to the maisons " young tike Dudley must have left his t.v on.
• After all the credits have run (You'll have to wait a long time; they honor everyone from J.K. Rowling and Richard Harris all the way down to the foley artists and key grips), the film makers throw in a little extra scene. We see Diagon Alley, and there's a new book in the window of the bookstore: "Who am I?" by Gilderoy Lockhart. The cover photo shows Lockhart in a straightjacket with a dumb and vacant stare on his face.
  

Mistakes

• In the movie during the filming emma( hermione) broke her wrist and when she is giving the polyjuice potion to ron and harry, when she lifts her arm you can see part of her cast that was supposed to have been covered by her robe.
• At the end of the movie, Dumbledore says that Harry Potter possesses many of the talents Voldemort himself valued. He meant to say Salazar Slytherin.
• Height diffrences are bigger in the beginning
  
• Harry's glasses go from being too small to fitting
• If the basilisc killed by looking people directly in the eye, why did moaning murtle died if she wears glasses?!?!?! She couldn't be looking directly if her glases were on like th book says....
• When Harry and Ron are hidden under the invisibility cloak, Lucius Malfoy gets in Hagrid's House saying that he called hogwarts and they told him that the headmaster was there. But how can he have called Hogwarts if There aren't telephones in the Wizard's world?
• All the spiders ( except Aragogue) Have 9 "legs". The real spiders have 8 instead...
• ginnys eyes in the movie are blue
  
• After he comes out of the wet chamber the sock he gave to Dobby was perfectly dry
• in the movie the basilisk has many teeth where as in the book it only has two gigantic fangs, and when one of the fangs sinks into Harrys arm, he removes a fang from it but there is no fang missing from the basilisks mouth
• at the end when Dumbledore, Hayy and Lucius are in Dumbledore's office, you can see part of Lucius' real brown hair
• Some of the differences I've found are: As Harry walks into his room, his hair is flat. They cut to Dobby and return to Harry, but now his hair is messy.
  
• During the filming, Emma Watson broke her wrist. In the trailer, (credits) you can see the cast sticking out of her robes. (From Deanne Toomer)
• In the first comparison of the movie and the book of the chamber of secrets it says that Dobby dropped a cake onto lady, but in England pudding is sometimes in a form similar to cake,
• it was a pudding dropped on the woman in the movie, not a cake, they even mentioned that Harry droped a pudding on her.
• The "Snake" in the film has EARS! (snakes DON'T have ears!)
• (you will only understand this if you have seen the deleted scenses for hp1)
  if you notice, in one of the deleted scenes, harry(radcliffe) and hagrid(coltrane) are in a subway. harry is reading off his school supplies, he runs into dragonhide gloves. he asked if the were really from a dragon , and hagrid said that it's not from a penquin(funny) then says that he'd like a dragon.
  later in the movie(in the film, not the deleted scenes) after harry, hermione and ron are coming back from seeing norbert. harry says "hagrids always wanted a dragon, told me first time i ever met him"! so that part only makes sence if that deleted scene is n the movie
