10 Things You Might Not Know About Harry Potter

I love entertainment. My likes are movies, television, books, Disney and more.


Let’s face it, filmmaking has its restrictions. Translating a book into a movie is hard work and not every detail that is in the books is going to make its way into the movies. Some storylines will have to cut, some scenes will have to be adapted and some details will be changed. The Harry Potter movies were made to entertain and to transmit the amazing story of Harry Potter in visual form to the world. Not everyone has read the Harry Potter books and the movies were created not only to please the readers of the saga but also to please the audience of nonreaders. That said there are some details that didn’t make the final draft of the movies, and sometimes not even the books. I wanted to create a list of some of these details that a lot of people don’t know about Harry Potter and that they might find interesting. These details can bring a little closure to people who thought that there were some plot holes in the story and there are details that are just plain fun to know. Enjoy!

JK Rowling and Harry share a birthday

It’s not by happenstance that Harry and Rowling’s birthday coincide. JK Rowling, the all-powerful creator of the series, made sure that she would always be even more connected to her character of Harry Potter. What better way to do that than by having the same birthday! This makes it pretty easy for the fans to remember. Now every year on July 31, not only is JK Rowling celebrated but her beloved character as well. JK Rowling also created other characters' birthdays on easy to remember dates. The twins Fred and George Weasley’s birthday is obviously dated on April Fool’s Day, April 1st. Voldemort himself has a significant date for his birthday. He was born on New Year’s Eve.

Hermione started an organization called SPEW

We all know that Hermione was the cleverest witch at Hogwarts. Besides her many adventures with Harry Potter, when we imagine Hermione, we imagine her studying and devourng her books. But Hermione was also an activist. She felt it was unjust how wizards treated house-elves, the small loyal magical creatures that serve a wizard in their homes. The most well-known house-elf in the Harry Potter saga is Dobby, who was the Malfoy’s house-elf until Harry freed him by tricking his master Lucius Malfoy into giving him a piece of clothing. As we see in the movie Chamber of Secrets, Lucius abused Dobby, and he definitely was not the only wizard that mistreated their faithful servants. Most house-elves don’t mind this treatment. They are accustomed to this way of life and this is just the way this has been forever. But Hermione could not stand this injustice and she created the organization called the Society for the Promotion of Elfish Welfare, S.P.E.W. for short. She barely had any followers but she was loyal to her cause. Following Harry’s example, she even tried to free the house-elves at Hogwarts by tricking them into taking some hats and socks she knitted. It was unsuccessful.

Filch is a Squib

A squib is a non-magic person born of wizard parents. A squib should not be confused for a muggle. Squibs have such a low level of magical power that they are not able to perform magic of any kind. Argus Filch, the Hogwarts caretaker, is one of these beings. Born of magical parents and knowing no other world than the wizarding world, Filch had no other choice than to remain in a world where he would be an outcast. He acquired a position in Hogwarts where he watches over the halls of the school where he sees magic everyday without being able to perform it himself. He wanders the corridors with his pet cat Mrs. Norris, with whom he has an unusual relationship. Some Squibs are known to have a special connection with cats. Filch and Mrs. Norris seem to understand each other. When Mrs. Norris notices a student doing something they are not supposed to do, she swiftly informs Filch who gets there within seconds to dole out punishment.

Messrs. Moony, Wormtail, Padfoot and Prongs

Besides showing us a glimpse of their existence via the Marauders Map on Prisoner of Azkaban, the filmmakers completely ignored the storyline of the Marauders. The Marauders were the ones that created the Marauder’s Map that Fred and George Weasley gave to Harry on his third year at Hogwarts. They were made up of Remus Lupin, Peter Pettigrew, Sirius Black and James Potter. They were the best of friends and committed mischief together on their years at Hogwarts. When the boys discovered that their friend Lupin was a werewolf, hence the name Moony, they secretly became Animagus, which meant that they could transform themselves into animals, as to keep his friend company on the nights that he transformed. James, or Prongs, transformed into a Stag, Sirius, or Padfoot, was able to transform into a Dog and Pettigrew, or Wormtail, was a Rat, both the animal and the traitor, like we find out in Prisoner of Azkaban.

Alice and Frank Longbottom

Neville's parents are institutionalized

Not much is known about Neville Longbottom. He is usually turned to as comic relief in the movies, but there is much to Neville that meets the eye. From what is shown in the movies, you wouldn’t have any idea that Neville almost possessed Harry’s fate. Neville’s parents were Aurors, who are the wizards that battle the Dark Arts, and were members of the Order of the Phoenix, the secret organization formed by Dumbledore to defeat Voldemort. The prophecy that predicted the defeat of Lord Voldemort said that the boy who would defeat him would be “born to those who have thrice defied him, born as the seventh month dies”. This could have been any of the two boys, Neville or Harry. Voldemort chose the one who he thought would be more likely and who he identified the most, Harry. After he marked Harry as his equal when he was a baby and was destroyed, Bellatrix Lestrange wanted to find out what happened to her master. So she captured and tortured Frank and Alice Longbottom with the Cruciatus Curse. The torture drove Neville’s parents insane and now they reside in St. Mungo's Hospital for Magical Maladies and Injuries.

Peter Pettigrew dies by his own hand

Another very important scene not shown in the movies is Peter Pettigrew’s death. We know that he was a traitor, that he gave Lord Voldemort the information of the whereabouts of the Potters that lead to him killing Harry’s parents. We know that he framed Sirius Black for the murder of innocent muggles and that he spent years hiding in his Animagus form as Ron’s rat Scabbers. We know that after Sirius found out his whereabouts Pettigrew ran and joined Lord Voldemort. And we also know that he helped Voldemort regain his human form and he remained his lackey into his end. But, what people don’t know is his fate, what happened to him after he imprisoned Harry and Ron in Malfoy Manor. As much as we hate Wormtail, he did feel bad for what he had done. When Harry reminded him of the debt he owed him after he spared his life in Prisoner of Azkaban, Wormtail hesitated and this reluctance made the hand that Lord Voldemort created for him on Goblet of Fire to turn on him and murder him.

Headmaster Albus Dumbledore

Dumbledore is gay

Even though it’s not said exactly like that on the books, JK Rowling has stated that when she wrote the character of Dumbledore she imagined him as gay. On the last book of the series, Harry Potter and the Deathly Hallows, we get a glimpse of what she meant. Dumbledore had a very powerful friendship with another wizard named Gellert Grindelwald. Grindelwald was what you might call a dark wizard, he was interested in world domination and was enlisted Dumbledore’s help to do so. While searching for the Deathly Hallows and planning to take over the wizarding world, Grindelwald and Dumbledore grew close, enough so that Dumbledore fell in love with him. It wasn’t until a fight broke out between them, that resulted in the death of Dumbledore’s sister Ariana, that the wizards parted ways. Later when Grindelwald was becoming a serious threat in the wizard world, Dumbledore regrettably defeated the powerful wizard. Grindelwald spent the rest of his life in the wizard prison Nurmengard until Voldemort killed him.

Harry named the kids

In the Prologue of Deathly Hallows movie, we see the main characters all grown up and on Platform 9 ¾ with their kids. We know that Harry married Ginny and that Ron married Hermione. We also know that Harry and Ginny had 3 children and that Ron and Hermione had 2. And that’s it. The books tell us a little bit more, like the names of their children and their ages at that time. Ron and Hermione’s older child Rose was starting her first year at Hogwarts at that particular time, so she must have been 11 years old. She was rather nervous about not being sorted into Gryffindor. Hugo their smallest hadn’t started Hogwarts yet, so he must have been around 10 years old. Ron and Hermione went a little bit more conventional when naming their children, unlike Harry and Ginny. Their oldest child is on his second year at Hogwarts and his name is James Sirius, as homage to Harry’s father, James Potter, and Harry’s godfather, Sirius Black. The second child was starting Hogwarts at the time, so he also must be 11 years old. His name, which is mentioned in the movie, is Albus Severus, Albus for Harry’s mentor Albus Dumbledore and Severus for the bravest man he has ever met and his former Hogwarts Professor Severus Snape. The littlest child hasn’t started Hogwarts yet just like Hugo, her name is Lily Luna, Lily for Harry’s mother and Luna, we are guessing, for Harry and Ginny’s dear friend Luna Lovegood.

Neville becomes a Hogwarts Professor

We know that Harry and Ginny got married and so did Ron and Hermione, but what of Neville and the others. What happened to them? It is mentioned in the books, and not even hinted at in movies, Neville eventually became a Hogwarts Professor. In what field you might ask, well in Herbology of course. The movies give us little hints that Neville was fascinated by plants, like the fact that he was very proud of his Mimbulus Mimbletonia, the plant that we see him with in Order of the Phoenix. After the final battle in Deathly Hallows, JK Rowling said that Neville, Ron and Harry were working as Aurors to finish the reign of the Death Eaters. After that job was done, Neville went to work at Hogwarts.

Neville and Luna don’t end up together

As mentioned before Neville returns to Hogwarts and becomes Professor Longbottom. In the movie Deathly Hallows, Neville apparently was in love with Luna Lovegood of Ravenclaw house. This was added to the movie because everyone, myself included, always felt that Neville and Luna make the perfect couple. They are both weird and outcasts. JK Rowling later stated that they never ended up together. Neville eventually married Hannah Abbot of Hufflepuff house who became the landlady of the Leaky Cauldron. Way to go Neville! Luna who was always fascinated with magical creatures married Rolf Scamander, grandson of Newt Scamander the author of the book Fantastic Beasts and Where To Find Them. They went on to have twin sons, Lorcan and Lysander.

I love Harry Potter and it's good to know these things! But I really do think Neville and Luna would have made the perfect couple!

Anonymous on September 22, 2014:

It's a rumor that J.K. Rowling is starting a sequel to the series, about their kids!!!!!!!

Kristina Pitts from Newry, South Carolina, United States on September 03, 2014:

Knew it.

Elizabeth Wilson from Tennessee on June 06, 2014:

I knew all but the first one. :) I know there have to be things cut out of the movies, but come on!!! They didn't tell about the Marauders! Or Alice and Frank Longbottom! Great Hub that I think will really compel people who haven't read the books to do so! Thanks so much!

Salo Lopez from Massachusetts - U.S.A on May 20, 2014:

Interesting data!

This make you want to read the books.

Great hub.

padfoot on February 07, 2014:

knew all of these "Things you might not know about Harry Potter."

Sia on December 31, 2013:

@Anica C:

Remus isn't an animagus! Sirius, Peter and James Potter I were animagi to keep the werewolf Remus company on full moons. Harry's patronus is a stag.

Anica C on November 18, 2013:

James isn't an animagus. Just Remus, Sirius and Peter are. James's patronus is a Stag.

Mel Carriere from Snowbound and down in Northern Colorado on October 20, 2013:

I loved the Harry Potter series after I absconded with book 1 when my son brought it home from school. It's not just for kids, it's a brilliant read for adults too. Great hub idea!

YadiraE (author) from Puerto Rico on August 14, 2013:

I completely agree Michelle! The Marauders storyline was my favorite. People who haven't read the book are missing so much! They don't understand how rich is the world that JK Rowling has constructed. I have a hard time trying to explain it to some people.

Michelle Widmann on August 13, 2013:

I've read the books a number of times, and it constantly upsets me that a lot of these details weren't in the movies - the Mauraders' identities, the explanation as to why Snape was the half-blood prince, Voldemort's back-story, all things that I think are more important than showing a lot of the romantic progress of Ron and Lavender Brown, or extended scenes of Harry and Hermione being chased by were-Lupin. Sigh.

YadiraE (author) from Puerto Rico on July 30, 2013:

Thank you Lisa! Glad you enjoyed the Hub!

Lisa from WA on July 24, 2013:

Great facts on Harry Potter! I knew a few of these but the last two I definitely hadn't heard before. Thanks for sharing! I haven't read the books in years now so maybe I'll go reread them now that I know a few new facts.

Becky on May 10, 2013:

Good information if you've never read the books. However James Sirius age/school year is never actually mentioned. A percentage of fans always assume he is in at least his third year but nothing has ever being confirmed or denied.

wingadium leviosa!

YadiraE (author) from Puerto Rico on December 12, 2012:

Thank you AI7!! I'm tired of all the negativity!!

Al7 on December 11, 2012:

Seriously, what is with some of the comments? A sense of arrogant superiority or something. Try reading the article properly Instead of just dismissing it with a know it all attitude.

No, you won't have known 'everything' not all was actually revealed I'm either the books or films.

Also, it's very clear that a chunk of this information is for those who haven't read the books, so fills in holes left by the films.

Tamara's comment is a classic example of this, stop being an 'insufferable know it all' so to speak.

Honestly, like a bunch of children, desperate to look like they casually know everything.

Good article by the way

Falcon213 on September 14, 2012:

I don't think it should be taken upon so lightly, that A.D. being gay is a canon fact. One may believe whatever one want, but neither him being gay or straight is an indisputable fact. She only said she imagined him as gay while writing. I have nothing against gay people, but I didn't imagine him gay while reading the books, also not at all in the seventh book either. My Dumbledore is Harris and not Gambon, and as good as assexual instead of beeing gay. Anyone trying to force it on me that he is canonically gay can just go and bother with something else.

N on August 28, 2012:

Seriosuly? What about this is news?

Tamara on July 11, 2012:

I'd be more impressed if I didn't already know all of this.

Shasta Matova from USA on July 03, 2012:

I haven't read the books but have seen all of the movies. I found this very helpful. Thanks.

Peggy Woods from Houston, Texas on June 26, 2012:

I have never read the books but did watch one of the movies on TV. I think that people who are not all that familiar with Harry Potter will find your hub informative and useful. "Voting it so. Thanks!

Guido on June 19, 2012:

I know everything :l Who read all the book already knows about this things...

Me on June 09, 2012:

If you read the books,you can find almost everything that is mentioned here. I think that this is not a very well informed site,because i have read all of the HP books and i knew almost all of this.

sweetguide from River side on February 14, 2012:

Very good hub, All are really Good points you mentioned. Thanks dear YadiraE

Moody on January 17, 2012:

I knew all of these especially the nevilles parents one bellatrix says it he says it and hermoine does too. If you read the book you should know all but nevilles job was a new one to me

Alexander Thandi Ubani from Lagos on September 18, 2011:

Very informative piece and well written too. Excellent. Bless you

Rob from Oviedo, FL on September 05, 2011:

I'd have loved to have seen more of the Mauraders. If JKR ever wants to write more Potter books, she should write a prequel about those guys and Lilly.

We get a slight (but unclear) hint of the fate of Nevill's parents when we see him crying as the spider is tortured by the Crutiatus Curse in "Goblet of Fire". If your familiar with the books, you know why he reacts that way but if your not, the scene doesn't make such sense.


Glen619 from Camden, New Jersey on September 05, 2011:

wow i read and watched all the potter series but did not know that Dumbledore was gay and about the future fate of Neville and Luna.

Indigital on September 04, 2011:

Big disappointment about some of the bits, especially Neville's parents. It would've put more character into the first Hogwarts battle.

JT Walters from Florida on September 04, 2011:

Hi Yardia,

I just took my son to see this film. Thank you for all the clarifications. I understand now.



caitlin on September 04, 2011:

you would know all of these if you had read the books

Lucy on September 04, 2011:

Great and awesome data!!!

Jess on September 04, 2011:

If you can read this article, you can read the books.
