Some Harry Potter lines never left the fandom. They escaped the books, colonised the movies, and quietly embedded themselves into pop culture as memes, tattoos, and emotional support quotes. Now, with HBO stepping into the Wizarding World and promising a more faithful, long form retelling of J.K. Rowling’s novels, the pressure is real.
More than this series needs a richer world-building and sharper character arcs, it needs to get the words right. Because in a story powered by prophecy, love, sacrifice, and loss, a single line can carry more magic than an entire wand battle. From Professor McGonagall's iconic alliteration to Snape’s final, devastating truth, these are the most unforgettable Harry Potter lines the HBO series should absolutely recreate, word for word, pause for pause, and with the emotional impact fully intact.
Severus Snape's introduction in Harry Potter and the Sorcerer's Stone
The moment we first meet Severus Snape the Potions master in the very first book and film, it's clear that he will be with us for a long way. His first introduction in class is a long instruction of what fans should expect and implore in his class, and honestly, it just sets the record straight for who we see Snape as in the later arcs.
"There will be no foolish wand-waving or silly incantations in this class. As such, I don't expect many of you to appreciate the subtle science and exact art that is potion-making. However, for those select few who possess the predisposition, I can teach you how to bewitch the mind and ensnare the senses. I can tell you how to bottle fame, brew glory, and even put a stopper in death. Then again, maybe some of you have come to Hogwarts in possession of abilities so formidable that you feel confident enough to not pay attention!" — Severus Snape
A reenactment of these lines from Paapa Essiedu would surely be iconic and it will be interesting to see how he embodies the Half-Blood Prince!
Professor McGonagall's sharp remark in Harry Potter and the Goblet of Fire
Professor McGonagall has given us some of the most iconic lines in the franchise. Whether she is icily snapping back at Dolores Umbridge or showing Harry the right way with equal parts affection and exasperation. One of her best lines came in the fourth film, when she is telling the Gryffindors about the Yule Ball, and she reminds them to be dutifully mannered and not behave like a- the iconic tongue twister- "babbling, bumbling band of baboons."
"The house of Godric Gryffindor has commanded the respect of the wizarding world for nearly ten centuries. I will not have you, in the course of a single evening, besmirching that name by behaving like a babbling, bumbling band of baboons!"
Janet McTeer's spin on this line in the television series will definitely be iconic. Especially if it's followed up with Fred and George Weasley's competition to say the lines!
Sirius Black's reassurance to Harry in Harry Potter and the Order of the Phoenix
The last film where we met Sirius is still his most emotional appearance on screen. Especially when he is reassuring Harry in his moment of self-hatred and self-doubt, as Voldemort continues to penetrate his mind during Harry Potter and the Order of the Phoenix.
During Harry's last meeting with Sirius, they talk in his old bedroom as Sirius shows him his family tree and they talk about James Potter. Shortly after, Sirius tells Harry some of the most important words he will ever hear:
I want you to listen to me very carefully, Harry. You're not a bad person. You're a very good person who bad things have happened to. You understand? Besides, the world isn't split into good people and Death Eaters. We've all got both light and dark inside of us. What matters is the part we choose to act on. That's who we really are.
Albus Dumbledore's last meeting with Harry Potter
Albus Dumbledore and Harry Potter's last meeting is at King's Cross during Harry Potter and the Deathly Hallows 2 where Harry escapes to briefly before waking up from Voldemort's killing curse. For a brief moment, Dumbledore and Harry talk about what happened, and Dumbledore gives him a true lesson on living and loving, and tells Harry how help will always be given at Hogwarts to those who ask for it.
"Help will always be given at Hogwarts, Harry, to those who ask for it. I've always prized myself on my ability to turn a phrase. Words are, in my not so humble opinion, our most inexhaustible source of magic, capable of inflicting injury and remedies. But I would, in this case, amend my original statement to this: Help, will always be given at Hogwarts to those who deserve it. Do not pity the dead, Harry. Pity the living. And, above all, all those who live without love."
It's one of the most poignant moments in the movies, and one that truly shows Harry the true power of love. Watching these lines recreated would be a delight to watch on the TV show, especially the lengthier turn the scene would take in light of the series being longer.
"Always"
Yep this iconic Severus Snape is what most fans are looking forward to most for the movies. The scene in Harry Potter and the Deathly Hallows 2 where Severus Snape reveals that he still has Lily Potter as his patronus and Dumbledore asks him "After all this time?", to which Snape responds and says,
"Always."
What makes the line unforgettable is not the romance people meme it into, but the grief underneath it. Snape’s love for Lily is not rewarded, healed, or redeemed in any conventional sense. It survives humiliation, war, and decades of self-imposed isolation. Watching the quote recreated in the HBO series would feel like reopening an old wound in the best possible way. If done right, it would not feel recycled. It would feel devastating all over again, in the best way possible.
