Whether it be easter eggs that were simply overlooked, or secrets that were unveiled
00:04
via J.K. Rowling's Twitter account, Harry Potter has plenty of untold secrets across
00:08
the film series. From secret perforated eardrums to the troublesome Slytherins, Rowling has
00:14
had plenty of fun slowly leaking some of the Potter-trudes over the years. Her Twitter
00:20
account as well as the Pottermore page has served as the ultimate fountain of mythology
00:24
for fans around the world. In a made-up world filled with fantastical beasts and freaky
00:29
moving staircases, there are bound to be a few unexplained elements. The secrets that
00:34
Hogwarts contains are bountiful, but over the years the drawbridge has been lowered slowly,
00:39
revealing the truth behind the mystical and magical world of wizarding and what goes on
00:43
behind closed set doors. Let's take a look at some of the sneaky secrets that have managed
00:49
to slither out of the Hogwarts set over the years. Hold on to your broomsticks because what
00:53
we're about to tell you might just blow you away. And with that in mind, I'm Ellie with
00:59
WhatCulture here with nine obscure Harry Potter movie secrets that took years to discover.
01:05
Number 9. Rupert Grint wasn't acting during the Aragog scene. It turns out wizards aren't
01:11
the only ones who are scared of spiders. In an interview that took place after the release
01:16
of the film The Chamber of Secrets, Rupert Grint had a secret of his own that he revealed
01:21
to the world. What you may have thought was excellent acting in the Aragog scene was actually a genuine
01:27
phobia that the actor was attempting to harness. His fear goes as far as making him check his
01:32
shoes every morning to make sure there are no spiders in there. Maybe he checks his coffee for
01:37
slugs too. Which is worse, filming a scene with a bunch of spiders or having to throw up a whole
01:41
load of slugs? Poor Rupert did not have it easy on the set of Harry Potter and he probably came away
01:47
with a few new fears on top of the already existing ones. As it turns out, Weasley's fear of spiders
01:53
stems from Rowling's fear of spiders in real life. Could there be a spell for curing arachnophobia?
01:59
Number 8. Harry's broken glasses weren't a prop. Daniel Radcliffe was made to play Harry Potter.
02:06
He's just as clumsy when it comes to his glasses and ended up needing over 100 pairs to get through
02:12
the filming. If he wasn't losing them, he was sitting on them, stepping on them or simply taking
02:17
them home for his own little Harry shrine. At first, he claimed to have stolen a few pairs,
02:22
but he revealed in an interview that they were actually given to him as a gift after filming.
02:26
The broken glasses in the film were a very real prop and had over 160 stunt doubles. That's 160
02:33
pairs of broken glasses for eight films. 20 pairs for every movie. If only Oculus Reparo worked in real
02:41
life. It has also since been revealed that at first, Radcliffe was unable to wear the iconic
02:45
glasses without breaking out in a mysterious rash. The frames of the glasses contained ingredients
02:51
known as nickel that can be found in a lot of cheaply made jewellery and eyewear. It took them
02:56
a while, but they figured it out and Harry was given a very special pair of hypoallergenic glasses
03:01
and the rash went away. Number 7. Wizarding is international. The American sibling of the
03:07
prestigious school for magic was already hinted at during the Harry Potter film series, but Rowling
03:12
has since revealed that there are 11 wizarding schools worldwide and that they are all registered
03:17
with the very important-sounding International Confederation of Wizards. The fourth installment
03:22
of the series, The Goblet of Fire, revealed two of the 11 schools, naming them Durmstrang and
03:27
the same magnifique French school known as Beaubaton Academy of Magic. Since then, it has been
03:33
revealed that wizarding is a worldwide thing and is taught all over the globe in countries such as
03:38
Japan, Uganda, Brazil and Northern Europe, and each of the schools has its own specialities such as
03:44
Quidditch or Herbology and Magizoology. The Pottermore site now has an in-depth section
03:50
regarding the schools for curious fans to study. Would you attend one of the others or would you stick
03:54
to the classic Scotland-based school of Hogwarts? Apparently, they do look at your proximity to the
03:59
schools, so you might not have a choice in the matter. Number six, the books weren't actually
04:04
floating. It can be tough to find a troll to act in your movie or a freakishly large spider willing
04:10
to retake scenes, so a lot of the visual effects in the film series are done using CGI, but on the
04:17
odd occasion, the director will employ a very simple trick to achieve the desired effect. The books in the
04:23
Hogwarts library are known for rearranging themselves, but they aren't doing it all by themselves.
04:27
What actually happened is that there was a huge behind-the-scenes team consisting of green-gloved
04:32
individuals. The green gloves work in the same way as a green screen would, and the post-production
04:37
team just had to edit the hands out of the shot. The result is a fantastic shot in which it appears
04:43
that Hermione is grabbing a book from the air as it floats past and replaces it with a different book.
04:48
Now, this is some real-life magic that needs more appreciation than it gets. There are so many moving
04:54
parts in these movies that there are bound to be a few little tricks here and there so that they could
04:58
achieve the perfect moving staircase or talking hat. Number five, Vincent Crabb was fired. Have you ever
05:06
wondered where the third member of the Slytherin posse went? Turns out he was just as much trouble
05:11
on set as he was in the movie. Actor Jamie Waylett was fired from the film set after being arrested for
05:16
growing marijuana back in 2009. The character who stepped in to take his place was Blaise Zabini.
05:23
Blaise was, however, featured in the books but not meant to appear in the Room of Requirements scene,
05:27
causing fans to question what had happened to the original member of the trio. Losing the role in the
05:32
movie obviously wasn't enough to set the actor on a straighter path, and he was arrested again in 2011
05:38
for stealing from a shop during the London riots. You can take the boy out of Slytherin, but you can't take the
05:44
Slytherin out of the boy, it seems. Number four, Warner Brothers couldn't afford Madam Hooch.
05:50
Another secret that only the keenest of fans would have noticed is the absence of Madam Hooch from the
05:55
films. The Hogwarts flying instructor and Quidditch coach played a significant role in the books but
06:00
didn't feature as much as fans expected in the movies. We are first introduced to the character
06:06
played by Zoe Wanamaker in The Philosopher's Stone. Her role is to teach Potter how to fly and how to win.
06:12
She is written into the story throughout the books but doesn't make an appearance past the first
06:16
film instalment. Zoe puts the lack of her character being in the movies down to the fact that Warner
06:21
Brothers didn't want to increase her salary. In an interview, she said that she had asked for a pay
06:26
rise for the remainder of the series but was turned down. Clearly, Warner Brothers either weren't a fan of
06:32
her acting or of her character. Maybe the lack of Madam Hooch was for the better. Who knows?
06:38
Number three, Radliff, Watson and Grint were just being themselves. When filming for Harry Potter and
06:43
the Prisoner of Azkaban, the director at the time, Alfonso Cuaron, asked the main trio to write an essay
06:49
about their characters for homework. In true Harry, Hermione and Ron style, the trio tackled the task
06:55
appropriate to their characters. Emma Watson wrote a 16-page essay going into detail about her role.
07:01
Daniel Radcliffe kept it short but deep and wrote a meaningful piece that would have received top
07:06
marks if they were being graded. Rupert didn't do anything and turned up to set empty-handed, claiming
07:11
that his character would have done the same and therefore he had nailed the homework assignment.
07:15
This lesser-known behind-the-scenes secret captures just how perfect the casting was for the movie and
07:21
explains why the actors nailed their characters and the chemistry on set so well. The film series
07:27
went through quite a few directors but none of the changes ever affected how the actors interacted on
07:32
screen. Daniel, Emma and Rupert are highly skilled at what they do and were able to maintain their
07:37
character's identity despite the disruptions along the way. Number two, Alan Rickman had a soft spot for
07:43
Snape. Rumour has it that Alan Rickman was informed of his character's loyalties right from the start.
07:50
Apparently, when the actor was cast as Snape, JK Rowling told him about his love for Lily and
07:55
that no one else knew. As he was the only one to know this very important piece of information,
08:00
he would often reject direction from the directors on set. But he also couldn't let anyone in on the
08:05
secret, but it was all made clear when his broken heart was revealed in the Deathly Hallows.
08:11
Many on set thought that he was simply embodying his character's sass when the cameras weren't rolling,
08:16
but it turns out he had good reason for being as stubborn as he was about his character.
08:21
David Heyman, the producer of the Harry Potter film series, claimed that there were multiple times
08:25
Rickman refused to do as he was told and that it all made sense when the reveal happened.
08:30
Alan Rickman is another good example of excellent casting. Rickman understood the assignment and kept
08:36
his major secret until the very end, adding to the impact on everyone involved and everyone watching.
08:42
1. Helena Bonham Carter didn't know she'd stabbed a co-star
08:47
Helena Bonham Carter is known for her method acting techniques and has a long history of giving herself
08:53
wholly to the role at hand. Fortunately for the viewers, but unfortunately for some of her co-stars,
08:58
her role as Bellatrix Lestrange was no exception. While they were filming for the Deathly Hallows,
09:04
Helena let things get a little bit out of hand while acting in the scene where Lestrange has Neville at
09:09
Wand Point. Thinking that the wand was soft and cotton bad-like, Helena went to stick the wand in
09:14
his ear just as he moved his head towards her. The small movement unfortunately meant that Matthew
09:20
Lewis's eardrum was stabbed, perforating it in the process. Playing it off as if it were nothing
09:25
due to politeness and fear for the character, Lewis only fessed up to the injury weeks later. Bonham
09:31
Carter was apparently mortified and very apologetic. I mean, who can blame Lewis for not fessing up sooner?
09:37
Would you complain to Bellatrix Lestrange that she'd poked a little too hard at your eardrum?
09:41
I mean, Lewis really is a sweetheart in real life and he fits his character so well.
09:46
