Deleted scenes
The following is a list of scenes that appear in the book and that were not in the final cut of the movie but were included on the DVD as deleted scenes, more or less the same as they were written in the book. Alternate versions of included scenes are not mentioned here.
 * Colin Creevey and Justin Finch-Fletchley, who are both Muggle-born wizards, casually mention this fact in conversation to Harry. This is key for the reader and/or viewer to know when both fall victim to the monster of the Chamber of Secrets. Colin also mentions he's the only one in his family, even though his brother Dennis should know, which was likely why it was cut.
 * On the first day of Defence Against the Dark Arts, Gilderoy Lockhart hands out a pop quiz to see how well his students have read his books. The quiz is titled "Defence Against the Dark Arts: Second Year Essential Knowledge Test." Some of the questions are: "What is Gilderoy Lockhart's favourite colour?", "What is Gilderoy Lockhart's secret ambition?", "What, in your opinion, is Gilderoy Lockhart's greatest achievement to date?", "When is Gilderoy Lockhart's birthday, and what would his ideal gift be?", and "How many times has Gildeory Lockhart won Witch Weekly's Most Charming Smile Award?" (In the final cut, the class just consists of the attack by Cornish Pixies.)
 * Fred and George tease Harry by calling him a "seriously evil wizard" because he is widely thought to be the heir of Salazar Slytherin. Though Harry knows it's a jest, he is depressed because he knows much of the school really considers him "evil". (In the final cut, this is just omitted.)
 * A rooster's crow is fatal to the ears of a Basilisk, so Tom Riddle has Ginny destroy all of Hagrid's roosters. Harry sees Hagrid walking around with the dead birds in his hand. (In the final cut, roosters play no role in the film.)
 * Harry, Hermione and Ron debate whether Harry is related to Salazar Slytherin or not. (In the final cut, similar scenes such as this one occur many times, but in this particular one Hermione raises the fact that Slytherin lived over a thousand years earlier and that Harry very well could be.)
 * Harry is chased by the rogue Bludger and flies through the Slytherin stands with it close at his heels, prompting the spectators to scream. (In the final cut, he is still chased by the Bludger, but he does not fly through the Slytherin stands.)
 * Once Harry leaves the library, Ernie Macmillan talks to Hannah Abbott about Harry and how he believes him to be the heir of Salazar Slytherin. Harry, however, overhears them. Ernie tells Hannah how he told Justin Finch-Fletchley to "lie low" in their dormitory for a while, because Justin "let it slip" to Harry that he was Muggle-born. Hannah does not believe that Harry is responsible for the petrifications, but Ernie is fairly convinced. (In the final cut, the scene is excluded because the scene with Justin telling Harry that he is Muggle-born is also cut.)
 * There are two scenes involving Crabbe and Goyle. The first one has Harry and Ron dragging them, unconscious, into a closet and taking a hair from their heads, and the second has Crabbe and Goyle awakening from their state, only to bump into Harry and Ron midway through their transformation back into their normal selves. (In the final cut, Crabbe and Goyle are just seen eating cupcakes that put them to sleep; their awakening is not shown.)
 * Harry, Ron and Hermione Granger discuss the diary and the mysterious owner, Tom Marvolo Riddle in the hospital wing. Ron remembers that Riddle was awarded a trophy for Special Services to the School fifty years previously, because he had to clean this trophy as part of his detention at the beginning of the year, and he kept belching slugs all over it. (In the final cut, this doesn't occur at all.)
 * After Harry finds out, incorrectly, through Tom Riddle's diary that Hagrid opened the Chamber of Secrets fifty years previously, he wakes up Ron to tell him so. (In the final cut, Harry tells Ron and Hermione the next day between classes.)

The following table lists differences of scenes in the book that were not in the final cut of the movie but were included on the DVD as deleted scenes. Alternate versions of included scenes are not mentioned here.
