It’s been very long since the Harry Potter series ended with Harry Potter and the Deathly Hallows. However, it hasn’t stopped fans from talking about it and getting excited about the story at every opportunity they get. Whenever there’s a chance to talk about the lore of this universe, you bet that there will be many people ready to do so.
One of the reasons that Harry Potter is so popular is because of how deep the universe is. Even if you read all of the books and watch all of the films, there’s still so much more information that you won’t know. Rowling has created the Wizarding World with depth and offered more to learn apart from the classic story.
So here are 25 things you didn’t know how about Harry James Potter.
25. In the far distant past, Harry and Voldemort share a common bloodline. Following the founding of wizarding surnames back through the years, the name “Ignotus Peverell” (who created the Invisibility Cloak) comes up in both character’s family trees. It’s a small (magical) world after all, making these enemies…distant cousins? – Source
24. Remember those moving chocolate frog cards from the first Harry Potter book? J.K. Rowling revealed that after Harry, Ron, and Hermione became household names following the Battle of Hogwarts, they were further immortalized on these iconic collectible cards. – Source
23. According to the J.K. Rowling, “Potter” was the surname of a family who lived nearby when Rowling was seven. She liked the name so much that she later “borrowed” it. Of course, it’s a safe bet that the original family is probably chuffed about the connection.
22. Rowling shares her birthday with Harry Potter. Both Harry and Rowling were born on July 31 in England. It’s worth noting this date makes them each Leos, the astrological symbol marked by a lion, and therefore destined for the leonine house of Gryffindor? Coincidence, or maybe not? – Source
21. Harry was never a real Horcrux, at least not by magical textbook definition. According to Rowling, a Horcrux must be intentionally created, and it’s clear in the books that Voldemort wasn’t exactly happy over having a piece of his soul housed in the body of a kid, especially a kid that ended up foiling his plans to take over the world. – Source
20. Fulfilling fanfiction fantasies the world over, Rowling confirmed that she had toyed with the idea of putting Harry and Hermione together. She argued that Ron and Hermione’s amusing, but admittedly hostile dynamic, may eventually lead to “fundamental incompatibility” in adulthood. Meanwhile, Rowling dropped hints that an intimate tent scene between Harry and Hermione in Deathly Hollows was written with a tinge of whimsy for the not-to-be couple. – Source
19. Since Harry got his Parseltongue ability from the piece of Voldemort’s soul he held, it makes sense that his special linguistic ability died with the evil wizard. Considering Harry’s reluctant embrace of all-things-Dark-Lord throughout the series, he may not have missed the ability much. – Source
18. Harry’s green eyes were compared to his mother Lily’s near a lot in the series. It’s not surprising then that fans noticed the Harry Potter in the movies sported a pair of non-canon baby blues. Apparently, this inaccuracy was not for lack of trying—actor Daniel Radcliffe tried a pair of green contact lenses but suffered an allergic reaction. – Source
17. Harry’s parents are killed on Halloween. 10 years later to the day, an 11-year-old Harry, Ron, and Hermione defeat a troll in the Hogwarts bathroom. Although Hermione was previously not friends with Harry and Ron, this event forms a strong bond between the trio. The date is significant when considering that on the same day Harry’s family once fell apart, he later finds a makeshift family. – Source
16. According to Rowling, Harry’s beloved Firebolt is a unique make of flying broomstick. Harry was one of the first wizards to own one, and considering their expense, very few were made. Further, the high-end craftmanship involved in the ironwork is dependent on mercurial goblins who tend to quit or go on strike frequently. – Source
15. Harry’s days in the DA (Dumbledore’s Army) foreshadowed his future career as head Auror and, even bigger, his eventual role as head of the Department of Magical Law Enforcement. Later on, Harry even gives lectures at Hogwarts for Defense Against the Dark Arts students. – Source
14. Although Rowling’s text doesn’t give precise years from the outset, calculating events in the magical realm lands Harry’s birth at 1980. This means that he arrived at Hogwarts in 1991, placing the timeline of the books slightly behind the series’ real-world publication. – Source
13. Harry’s wand measures at 11 inches and is composed of phoenix feather and holly. It also has the same core as Voldemort’s wand, symbolically marking them as equals. – Source
12. For fans keen on Harry’s parents’ backstory, their patronuses seem to symbolize a union that was meant to be. James’ patronus was a stag, and Lily’s was a doe. In true orphan Bambi-like form, their surviving son grows throughout the books to form a stag patronus as well. – Source
11. J.K. Rowling said herself that Michael Jackson tried to convince her to turn her Harry Potter novels series into a full stage musical. Rowling ended up turning Jackson down because she believed the musical would not have worked that well for her series. The musical did have the potential to be incredible with Michael Jackson’s brand of musical style, but ultimately it never happened. – Source
10. Harry and Ron did not graduate from Hogwarts. After the Battle of Hogwarts, Hermione returned to school and passed her NEWTS with flying colors. Harry and Ron, however, chose to be done with school. They joined the Ministry of Magic. It makes sense why Ron would have no interest in returning, but for harry Hogwarts was the only place he ever felt home. However, his choice was probably for the best. Hogwarts post-battle probably held a lot of traumatic memories for Harry and he was definitely needed in the now-depleted Auror department. – Source
09. In an interview, Daniel Radcliffe admitted to succumbing to a serious drinking problem during the filming of the later Harry Potter movies. “I was living in constant fear of who I’d meet, what I might have said to them, what I might have done with them, so I’d stay in my apartment for days and drink alone,” said Radcliffe, “I was a recluse at 20. It was pathetic — it wasn’t me. I’m a fun, polite person and it turned me into a rude bore.” Radcliffe also admitted to being notoriously unhealthy and antisocial in his later teen years. Luckily, he recovered from his alcohol dependence in 2010 and even said that Gary Oldman was a major help in convincing him to recover, as someone who had battled alcohol addiction as well. – Source
08. In 2000, Scholastic gave schoolchildren across the U.S. the opportunity to ask Rowling questions about Harry Potter. When one student asked her, “What made you think of the people’s names and dormitories at Hogwarts?” Rowling responded, “I invented the names of the Houses on the back of an airplane sick bag! This is true. I love inventing names, but I also collect unusual names, so that I can look through my notebook and choose one that suits a new character.” – Source
07. Alfonso Cuarón wanted Watson, Radcliffe, and Grint to write essays about their characters from a first person point of view. According to Heyman, “they all responded very much in character … Dan wrote a page, Emma wrote 10 and Rupert didn’t deliver anything.” Grint said, “I didn’t do mine, because I didn’t think Ron would. Or that was my excuse. At the time, I was actually quite busy with the real schoolwork involved with my exams, and I just didn’t do it. But in the end, it felt right because that’s what Ron would have done.” – Source
06. When Harry makes his first venture to Hogwarts in The Sorcerer’s Stone, many people look at him with awe. Many times, he’s cited as a great wizard that will go on to accomplish great things. There’s no denying that taking down a troll and defeating Professor Quirrel were both amazing accomplishments, but there’s just one problem: Harry didn’t cast a single spell in the first movie. This fact becomes more evident through repeated watches of the film. Ron and Hermione are both seen casting spells, but Harry never does. Instead, he relies more on his knowledge, wit, and Quidditch skills to get through his first year. While an interesting choice, it was a nice way of showing his newness to the Wizarding World.
05. There’s a scene near the beginning of The Deathly Hallows where many of Harry’s friends take polyjuice potion so that they can turn into duplicates of him. That way, the Death Eaters wouldn’t be able to figure out which one was the real Harry. The film shows all of the characters turning into direct copies of Harry. Despite it being such a simple scene, it took a long time to get it just right. Daniel Radcliffe had to go through 90 takes in order to accomplish the scene, just so that he could appear to be in multiple places at once. – Source
04. Ever wonder what happened to Harry’s magical grandparents? According to Rowling, “Fleamont and Euphemia lived long enough to see James marry a Muggle-born girl called Lily Evans, but not to meet their grandson, Harry.” The elderly couple succumbed to a deadly case of dragon pox just a few days apart. From there, James Potter inherited the invisibility cloak. So, while they weren’t present in the series, Harry’s grandparents were responsible for his possession of a lifesaving (and convenient) magical item. His maternal grandparents also died of natural causes before he was born. – Source
03. Despite how central they were to Harry’s character, James and Lily Potter don’t appear frequently in the series. Because of this, the filmmakers of The Sorcerer’s Stone thought it would be a great opportunity to give Rowling the credit she deserved for making the film possible. It was originally pitched to her that she would play the part of Lily Potter. However, in an interesting turn of events, she turned it down. – Source
02. Remus Lupin got a happy life of sorts when he married Nymphadora Tonks. By the time The Deathly Hallows rolled around, she was pregnant with a little boy. However, due to the impending war, Lupin met with Harry Potter to ask him if he would be the godfather to his son. Harry graciously accepted. Unfortunately, Harry would have to think about raising Teddy Lupin very soon because both Lupin and Tonks died during the Battle of Hogwarts. This didn’t cause Teddy to have a rough life, though. He went on to be very involved in Hogwarts. – Source
01. Out of everybody we hated in the series, Dudley was easily in the top 5. This spoiled brat made Harry’s life a living hell (when Harry was away from Hogwarts, that is). Yet, their connection didn’t end after The Deathly Hallows. After those climactic events, Harry and Dudley kept in touch and made it a point to visit from time to time. The intention for this was for their kids to get to know each other. Harry and Dudley mostly sat in silence during these meetings. – Source
