Trivia for Harry Potter and the Chamber of Secrets

• Daniel Radcliffe has said that "Harry Potter and the Chamber of Secrets" is his favorite book.


• Zoë Wanamaker does not appear in this film as Hogwarts' flying instructor, Madam Hooch. Her character was written out.


• Fourteen Ford Anglias were destroyed to create the scene where Harry and Ron crash into the Womping Willow.


• The Weasleys' car registration number is 7990 TD.


• The train station interior used in the film is Kings Cross in North London, whereas the exterior shot is actually St Pancras. The two stations are adjacent to one another, but not the same building. This was done because the architecture of St Pancras is much more visually appealing.


• In the UK, this became the first movie to achieve a million DVD sales in its first weekend.

• The script originally said that Hermione would hug Harry and Ron in the final scene. As the then 11-year-old Emma Watson was embarrassed about having to hug the boys in front of the entire cast, Chris Columbus allowed her to change the scene so that Hermione just hugs Harry then starts to hug Ron but the two get embarrassed and resolve to only shake hands. Watson also stated in a recent interview that she kept letting Daniel Radcliffe go too quickly, so the film was "frozen" for a few seconds to make the hug look like it lasted longer than it actually did.
