I have already had to admit what a HP nerd i am in a comment on one of my deviations (Albus Dumbledore), but since i've lost so much time to google for the cause i have no choice but to post the useless information i've found about HP.

Does anyone really care? Probably not, but here it is anyway;

...the mirror of erised is so named because erised is 'desire' backwards. It's also engraved with 'erised s'traeh ruoy tub ecaf ton ruoy wohs i' which is the reverse of 'I show not your face but your heart’s desire.'

...Richard Harris only accepted the role of Dumbledore (the original dumbledore) because his granddaughter threatened to stop talking to him if he didn’t!

...In the 3rd movie, the actors were told that the sweets in the honeydukes scenes were coated in lacquer to stop them eating any between scenes.

...In OotP, the number dialled to use the visitors entrance to the Ministry of Magic is 62442. The letters underneath those numbers on a standard mobile phone spell out the word "magic".

...On page 159 of GoF a first year by the name of natalie McDonald is sorted into her house (Gryffindor - for the brave at heart). JK named this character after a nine year old girl from Toronto who had emailed her to ask what would happen in the next book as she was dying of Leukaemia and wouldn't live long enough to read it. JK did reply, but natalie had died a day earlier.

...Fred and George Weasley's birthday is the 1st of April - April Fools Day.

...In muggle money a galleon is worth about £5.
*But exchange rates can vary.

...Director, Alfonso Cuarón asked each of the three main actors to write an essay about their characters. Emma Watson (Hermione) wrote a 16 page essay. Daniel Radcliffe (Harry) wrote a short 1 page essay. Rupert Grint never turned his in.
*Maybe they were just REALLY in character!

...According to the film, the Weasleys' car registration number is 7990 TD.

...Dudley's part in the 3rd movie consists of laughing once at the TV, and giving two gasps of surprise.

...It took the effects team 6 months to create the dementors.

...David Thewlis (Lupin) was originally considered to play Professor Quirrell.

...Over 3,000 girls turned up at the auditions for the role of Cho Chang in London on 7 February 2004.
*I would've if i fit the description - despite not being able to act.

...Ron's middle name is Bilius!

...For GoF, Daniel Radcliffe spent 41 hours 38 minutes underwater during the course of filming.

...At one point during training for the underwater scenes, Daniel inadvertently signaled that he was drowning, sending the crew into a huge panic to bring him back up to surface.

...In the 2nd movie there is a portrait of another famous wizard in DUmbledores office: Gandalf (It is above the door-frame and slightly to Harry's right).

...Hugh Grant was originally cast as Gilderoy Lockhart but was forced to withdraw at the last moment because of scheduling conflicts.

...The Mininstry of Magic set took 22 weeks to built and was on screen for less than 10 minutes!

...In the 2nd movie, 11 year old Emma Watson wass so embarassed about having to hug Daniel infront of the crew that she kept letting go of him too quickly and the scene had to be frozen to make it look as though it lasted longer.
