History Trivia / HarryPotterAndTheChamberOfSecrets

--->'''J.K. Rowling:''' The only character who is deliberately based on a real person is Gilderoy Lockhart. Maybe he is not the one that you would think of, but I have to say that the living model was worse. He was a shocker! [[MilesGloriosus The lies that he told about adventures that he'd had, things he'd done and impressive acts that he had committed... He was a shocking man.]] I can say this quite freely because he will never in a million years dream that he is Gilderoy Lockhart. I am always frightened that he is going to turn up one day. He is just one of those people from your past whom you feel you have never quite shaken off. I will look up one day at a signing and he will say, "Hello, Jo". Other people have contributed the odd characteristic, such as a nose, to a character, but the only character who I sat down and thought that I would base on someone is Gilderoy Lockhart. It made up for having to endure him for two solid years.

** There were some changes in the cast of the Latin American Spanish dub due to it being made in a different studio, such as Creator/VictorHugoAguilar replacing Creator/HumbertoSolorzano as Hagrid, or Keta Leonel replacing Magda Giner as the permanent voice for [=McGonagall=]. Creator/CarlosSegundo (Professor Snape) and Arturo Castañeda (Harry) also left because of disagreements with their salaries, and were replaced by Rolando de Castro and Claudio Velázquez, respectively.

* CaliforniaDoubling: In addition to the sets at Leavesden Studios, Hogwarts was represented in this film by Alnwick Castle, Durham Cathedral, Gloucester Cathedral, Lacock Abbey, and Oxford University. All of these locations carried over from the first movie, but some of them would not last beyond this one as the third movie would transition to filming most of the Hogwarts interiors at the studio. They would return to Oxford for the fourth and sixth movies, Gloucester Cathedral for the sixth movie, and Lacock Abbey for ''Film/FantasticBeastsTheCrimesOfGrindelwald'', but Alnwick Castle and Durham Cathedral never appear in the series again after ''Chamber of Secrets''.

--> '''Lucius:''' Let us hope that Mr. Potter will always be around to save the day.
--> '''Harry:''' Don’t worry. I will be.
** Hermione was supposed to hug both Harry and Ron at the end. But Creator/EmmaWatson was too embarrassed to hug both boys in front of a crowd of people. Thus came the compromise where she hugs Harry but only shakes Ron's hand. It ended up as an accidental foreshadowing of their future relationship (which didn't get hinted at until the fourth book). What's more is that the film had to be frozen for a few seconds because Emma kept breaking the hug too quickly.

** Allan Corduner voices Snape, Flitwick, Filch, Lucius Malfoy, and the Sorting Hat.

* InMemoriam: The film is dedicated to Creator/RichardHarris, who passed away a few days before the premiere.

* YouSoundFamiliar: Two retroactive examples in the Brazilian dub: Hamilton Ricardo played the Bazilisk's voice, and would reappear from the next movie on as Lupin, and Luiz Carlos Persy, who voiced Araragog, would be cast later as Voldemort.

* AbilityOverAppearance: The casting call for Tom Riddle insisted on actors aged 15-17. Christian Coulson, who was twenty three, gave the best audition and was cast. He did not, however, reprise the role for the sixth film, being deemed too old by that time.

** As noted above, Christian Coulson was twenty-three playing sixteen. Likewise, Creator/ShirleyHenderson, who plays school-age Myrtle, was ''thirty-seven''.

* DuellingMovies: In a repeat of their respective previous instalments' duel the previous year, the film came out one month before the movie of ''Film/TheLordOfTheRingsTheTwoTowers''. As before, the outcome was pretty much a tie and both were massive box office hits. To date, this is the last time the two franchises have competed at the box office. The ''Rings'' trilogy concluded in 2003 while the third ''Potter'' film came out in 2004, and the trilogy of ''Film/TheHobbit'' was released between ''[[Film/HarryPotterAndTheDeathlyHallows Deathly Hallows]], Part 2'' and ''Film/FantasticBeastsAndWhereToFindThem''.
