11Ford Anglias
Fourteen Ford Anglias were destroyed to create the scene where Harry and Ron crash into the Whomping Willow.
12Arachnophobia
Rupert Grint has a very real case of severe arachnophobia, to such a degree that he has still not watched the entire scene where Aragog and the spiders appear. In that scene, the look of fright on Ron’s face and his uncomfortable squirming throughout was not from acting but was due to Rupert being legitimately terrified.
13Dumbledore's office
The set for Dumbledore's office was, at the time of its construction, the most expensive set built for the films at that time. Both director Chris Columbus and production designer Stuart Craig agreed that, as headmaster, Dumbledore should have the most elaborate office possible. However, they were informed that the proposed design, with its massive stone columns, bookcases, curio cabinets, paintings on the walls, tables filled with various objects, antique desk and throne-like chair, and a giant telescope, would be far too expensive to produce. The producers ultimately were able to secure the funds needed to build the set.
14Vladimir Dobby
On an episode of ‘Have I Got News for You’, the panelists discuss an article claiming that the Russian President (later Premier) Vladimir Putin was deeply disturbed and offended that Dobby the House-elf seemed to have been created in his image. There is an undeniable resemblance either way.
15Hermione's Parents in Australia
In the opening of the film, when Hermione is called down to tea, we can hear her parents talking about Australia along with an announcer, presumably on the TV, talking about a country-side. This is a reference to the book, in which Hermione says she not only wiped herself from her parent's memories but gave them new identities and made them think that they'd love nothing more than to move to Australia, which we presume that they do.
16David Holmes
David Holmes, 25, Daniel Radcliffe's stunt-double, was seriously injured on the set of Deathly Hallows. He was performing an aerial sequence when he fell to the ground following an explosion, which was part of the stunt, and sustained a serious back injury. Although he initially hoped to return to work, it has since been reported that Holmes is paralyzed and now uses a wheelchair.
17Harry's scar
Harry's lightning bolt scar was applied by make-up teams approximately 5,800 times by the end of the series. Daniel Radcliffe had the scar applied 2,000 times while the rest were applied to stunt doubles and stand-ins.
