Harry Potter Theory — 25 Hidden Details You MISSED in the Harry Potter HBO Trailer. Machine-transcribed; use the interactive transcript above to jump the player to any line.
Oh Kidoki, my breakdown of HBO's new Harry Potter trailer is officially out, so if you haven't seen that already, go check it out as it gives a much broader look at the trailer as a whole. However, if you like nitpicking, which of course I love, then this is the video for you, and as in this one I'll be breaking down 25 of the biggest Easter eggs from the trailer. That is, the Tony Book references, hidden background details, bits of foreshadowing, and other moments that you probably wouldn't notice on a first watch. I covered a few of these on my breakdown, but they weren't really the focus, so I've gone a little more in depth. I'm sure there are way more than 25 in the entire trailer, but I just wanted to give it a go. Also, before we dive in, make sure to like the video and subscribe to the channel to support future content. Let's dive into it. Hannah Abbott and Lavender Brown, starting things off, we've got a detail that I actually half-court in my original breakdown. When Hermione approaches the other students on the whole galtic press and enthusiastically asks whether they enjoyed the summer reading, I concluded that one of the girls she was speaking to might be Lavender Brown.
And as it turns out, I was right, but what I didn't realise is that the other girl sitting beside her is Hannah Abbott. Lavender is obviously Gryffindor and Harry's here, while Hannah is a half-alpuff, and to both become much more recognisable later in the story. But instead of waiting several seasons until one of them suddenly needs to say something important, HBO is seemingly establishing these students from the very beginning. Lavender in particular is present throughout the books from year 1, whereas the films don't really give her recognisable identity until half-blood prints when her relationship with Ron suddenly becomes important. The house point hour glasses. Next up is something that was sitting almost directly in front of us, but I completely missed the first time around. When Professor McGonagall is leading the first years toward assorting ceremony, if you look at the background, you can apparently make out the four giant house hour glasses used to keep track of house points. As we know from the books, Gryffindor also threw in Ravenclaw and Hufflepuff each have one of these enormous magical counters, with different coloured gemstones rising and falling as teachers
award or deduct points throughout the year. I mean, how can Dumbledore award millions of unwarranted points to Gryffindor without these counters? Perseys Prefect Batch. Next up, we've got the weaselies around the table at the borough, and whilst Red and George are busy smashing sandwiches, and generally causing as much chaos as humanly possible, there's something much quieter happening with Perseys. He's receiving his shiny new Prefect Batch. I missed this the first time around, but a bunch of you commented about it on my breakdown video. Molly looks extremely proud. This is exactly where Perseys should be at this point in the story, because he has just become a Gryffindor Prefect as Ron prefers for his own first year at Hogwarts. And if there's one person in the entire Weasley family who's going to make sure everybody notices that little badge, it is absolutely Percy. West Ham posters. This is a tiny, tiny, tiny one, but during the footage inside the Gryffindor dormitory, if you look very carefully at the walls, there appears to be West Ham United posters, and these are almost certainly belong to Dean Thomas. For anyone who doesn't remember, Dean is a massive football fan in the books, actual Muggle Football, and specifically
supports West Ham United. This is exactly what I consider a proper Easter Egg. Nobody needed to put West Ham posters in this set, and 99% of people watching this series probably won't notice them. But some angel designing the Gryffindor dormitories apparently sat there and thought, okay, Dean Thomas lives here, what would Dean put on the wall? Neville's Mangle Wurzel. Next up, we've got herbology where in my original breakdown, I pointed out that Neville looked to particularly engaged in Professor Sprout's lesson, which of course makes perfect sense given his future aptitude for the subject. But there's actually something much more specific happening here. The enormous root vegetable level pulls out of his pot appears to be a Mangle Wurzel. Most notably, Neville seems to handle this enormous thing surprisingly comfortably, while some of the other students are having a considerably more difficult time. This is a pretty great little bit of foreshadowing because apology becomes one of the first areas of magic when Neville really excels. While he struggles with confidence and has trouble with plenty of other subjects early on, plants are almost immediately different. And of course, years later, Neville eventually returns to Hogwarts as the
Hibology Professor. Dean and Sheamus are already messing around. While Neville is busy demonstrating that he may actually have some natural talent for herbology, take a look at what's happening elsewhere in the classroom. Dean and Sheamus appear to be messing around with their own plant, basically playing some kind of hot potato with it. This is an unbelievably small detail, but it's still significant to me because it shows these aren't just characters standing perfectly still in the background waiting for Harry to do something important. I think this is the sort of background behaviour that can make Hogwarts feel considerably more alive because every single student in these scenes should theoretically be having their own Hogwarts experience, even when Harry isn't paying attention to them. The Chuddly Cannon's Batch. Next up, we've got what might be one of the cleanest actual Easter eggs in the trailer. Following the footage, we get a sort of Harry hugging Ron. And if you look very carefully at Ron's sleeve, there appears to be a Chuddly Cannon's Batch. For anyone who doesn't remember, the Chuddly Cannon's are Ron's favourite professional quidditch team, and unfortunately for Ron, they're terrible. His bedroom at the
barrow is decorated in their famous orange colours, and throughout the books, Ron continues supporting them, despite their absolutely abysmal record. And again, this is one of those little things that immediately makes Ron feel like someone who actually grew up inside Wizarding culture. Something these films didn't do that well. The Gryffindor Banner. Hidden amongst all the quidditch material is another really specific reference to Philosopher's Stone. At one point in the trailer, you can see Hermione performing magic on a large Gryffindor banner. And this appears to be the exact little sequence described in the book before Harry's first quidditch match. Dean Thomas paints a huge banner featuring a Gryffindor line, along with the words Potter for President, and Hermione then performs a tricky little charm that makes the paint flash different colours. This is a tiny paragraph. You could remove it from the adaptation entirely, and absolutely nothing about the story would change. But instead of removing it, HBO appears to have actually expanded it into something happening on screen. This is exactly the kind of thing I was hoping we'd get from the TV format. Harry is saying AccuForce. Next up is something I
completely missed on my first several watches. During the Transfiguration scene, Harry and Ron are attempting one of their very first exercises. But if you listen carefully to Harry, he appears to be muttering AccuForce. And interestingly, the official Harry Potter website has actually confirmed that this is what he's saying. But here's the thing. As far as I know, AccuForce isn't actually a previously documented Harry Potter spell. And I should know, because I've done an entire video covering all Harry Potter spells. Go check that one out if you haven't already. The closest spell I immediately thought of was Avifors, which is an existing Transfiguration spell that turns objects into birds and has appeared primarily in the Harry Potter video games. But that's obviously a completely different transformation. Here, Harry appears to be attempting the famous match to needle exercise from Philosopher's Stone, which means AccuForce could potentially be an entirely new incantation created for the HBO series, specifically for this transformation. Of course, the book says that loads of magical exercises are not necessarily giving us the actual incantations
involved. So the show has a pretty unique opportunity to flash some of this stuff out. And this may actually be our first look at a brand new spell created for the HBO series. The match to needle exercise. Continuing on the last point, what Harry is actually attempting in the Transfiguration scene is also directly out of Philosopher's Stone. We can clearly see matches sitting on the students' desks as they point their ones toward them, meaning this is almost certainly the famous first-year Transfiguration exercise where McGonagall asks everyone to turn a match into a needle. It's a really nice book accurate detail because this lesson is specifically used to show us just how difficult Transfiguration actually is. Most of the class struggles tremendously, while Hermione is the first person to make any meaningful progress, eventually managing to give her match a pointed end and a silvery appearance. One to movements. Not letting this particular classroom sequence die, there is another thing I noticed. The students' hands. In the trailer, our students appear to be performing much more deliberate one-to-hand movements while attempting
spells when compared with the films. They aren't just pointing the one at something and firing. Instead, there appears to be an actual physical technique involved. And I really hope this becomes an important part of how HBO depicts magic because the books repeatedly emphasize that spellcasting is something you actually have to learn. Obviously, swishing flick is the most famous example of this in the films, but it looks like spellcasting is about to get a lot more nuanced. The sorting hats mouth. Next up, we've got an absurdly specific book description detail. When the sorting hat begins to speak, its mouth appears to form out of a rip near the brim. And that's basically word for word how the moment is described in Philosopher's Stone. The book describes a rip opening near the brim, like a mouth, and that appears to be exactly what HBO has done here. Even generally, the new sorting hat looks considerably tattooier, older, and more misshapen than its movie counterpart, which feels very appropriate considering this thing has supposed to have been sitting around Hogwarts sorting children for about a thousand years. Queryl is already hiding something. Next up, we get our first proper look at Professor Queryl
sitting behind McGonagall during the sorting ceremony. And there is a notable absence of the enormous purple turban we grew accustomed to in the films. Why exactly? I'm not sure. That said, Queryl does still appear to have material covering his head, which is of course rather important because underneath it is a second face. It looks like HBO may be changing the exact design of Gross disguise, while still preserving the actual reason he needs one in the first place. As opposed not every single costume element needs to be visually identical to the films, but I do think I'll miss that purple turban. Ron's Hogwarts timetable Next up, we've got the prop that myself along with all of the other diehands have apparently decided to examine more closely than several genuine historical documents. Ron's Hogwarts timetable. At one point, something drops from a verb onto Harry and Ron's table in the Great Hall, and we get a surprisingly clear look at their actual weekly school schedule. From the timetable, we can make out core subjects like potions, charms, transfiguration, herbology, history of magic, defence against the dark arts, astronomy and flying.
But there's also a bit more to this timetable than expected. Prep, games and sporting fixtures Alongside all of the normal magical subjects, the schedule appears to contain periods marked prep, games and even sporting fixtures. Prep is presumably designated homework or independent study time. Games is interesting because the books never spend much time explaining what ordinary physical activity exists at Hogwarts outside Quidditch, and sporting fixtures seemingly means that Quidditch games themselves are actually built into the school calendar. And while all of this may feel absurdly mundane, it's exciting to see that they've apparently tried to create a genuine functioning school week rather than just having Harry blip from class to class. Double potions The timetable also appears to show longer blocks for certain subjects, most notably potions, which again lines up very nicely with the books, where Harry frequently describes having double potions. And of course these lessons are particularly memorable because Gryffindor shares potions with Sutheran, which brings us to one of the most ridiculous timetable details people manage to spot, colour coding by house. If you look closely, the individual lessons
appear to be marked with different colours, and some fans online have suggested those colours may actually correspond to the house Gryffindor shares that particular class with. Potions is green, and Gryffindor famously takes potions with Sutheran. Herbology is yellow, potentially representing Hufflepuff, and charms is blue, potentially representing Ravenclaw. Redblocks may represent lessons Gryffindor attends alone. Now I want to stress that I don't think we can call every part of this 100% confirmed until we get a crystal clear look at the timetable, but if that is genuinely what they've done, that is ridiculous because it means somebody worked out which house Harry and Ron share every lesson with. For a prop that lasts two seconds in the trailer, Ravenclaw finally has an eagle. One of the small, very book accurate detail comes from the newly redesigned house symbols. If you look at Ravenclaw's new emblem, the animal being used is an eagle, and that might sound completely normal if you've only ever read the books. But in the Harry Potter films, Ravenclaw symbol was actually changed to a Raven. Despite the name Ravenclaw, the house emblem in the books
is explicitly an eagle, and its colours are blue and bronze rather than blue and silver used in the films. The Midnight Dool Next up we have what looks like a pretty clear glimpse of one of the most notable Philosopher's Stone sequences completely removed from the original movie, The Midnight Dool. In the book, Draco challenges Harry to meet him in the trophy room at Midnight. Harry and Ron sneak out to meet him, Hermione follows because she's desperately trying to stop them from getting expelled, and Neville even ends up coming too. And based on visuals from the trailer, that appears to be exactly what we're seeing here. Harry and Hermione Neville are all seemingly running around Hogwarts together at night, then they encounter Fluffy. This is a nice tidbit to add because Neville is actually far more involved with Harry's group during this section of the novel than the original film suggests. Feltch in the trophy room. Continuing on the last point, there seems to be a very quick shot of Feltch searching around Hogwarts during this sequence, and it looks like he's standing in the trophy room, which is of course the exact location where Draco told Harry to meet him for the Midnight Dool. That makes this more than just a generic shot of Feltch wandering the corridors. It actually
seems to confirm that HBO is restoring the full sequence from the book. Draco sets Harry up, Feltch goes looking for him in the trophy room, Harry and the others are forced to run, and where do they eventually end up with Fluffy? One of the first things that stuck out to me about this moment is that Neville is there with them, which is exactly what happens in Philosopher's Stone, the book. After escaping Feltch, all four students accidentally end up in the forbidden third floor corridor and discover the enormous three-headed dog guarding the trap door. The original film heavily simplifies this entire storyline, essentially removing the Midnight Dool and changing how Harry Ron and Hermione discover Fluffy, but it looks like HBO is restoring the sequence. I'm very happy about this because it gives Neville a lot more involvement early on, and makes the discovery of Fluffy feel like the consequence of this entire mini-adventure rather than something the characters simply stumble into because the film needs them to. Ron's bloody face. Next up we're heading back to Quidditch. I covered this in my breakdown, but following one of the matches, we get a shot of Harry hugging Ron, and if you look close to it Ron's face, it's clear he's been in some sort of a
fight. And this of course points toward another small book scene that the film skipped over entirely. During the match, Malfoy spends most of his time antagonising Ron and the other griffin doors from the stands, and eventually Ron has enough and goes for him. Neville gets dragged into the chaos as well, and by the time Harry actually finishes the match, Ron is so busy fighting Malfoy that he doesn't even see what happened. It's a relatively minor moment in terms of the overall plot, but I actually think it does quite a lot for Ron. It shows just how quickly his loyalty to Harry develops, it makes his hatred of Malfoy feel much more personal, and it gives us some of that temper and fire that I think was occasionally softened in the films. Wizards Chess. Next up we get a shot of Ron playing Wizards Chess with Harry over Christmas, and while this looks like a fairly black little scene on the surface, it's actually doing some pretty important setup. Wizards Chess is one of the first things we see Ron being genuinely exceptional at. If you'll remember, when the trio reaches McGonagall's giant chess board protecting the Philosopher's Stone, Ron is immediately the one who understands what they need to do. He controls the entire game and
ultimately sacrifices himself so that Harry can continue. So the seemingly harmless little Christmas game is quietly establishing one of Ron's most important strengths, long before it actually matters. Harry's cloak. Next up we get Harry using the invisibility cloak for what appears to be one of the first times, and shortly afterwards we see him standing inside what looks like an abandoned classroom. And if we take a look behind him, the cloak is sitting there on the floor, and this tells us exactly where we are, in case it wasn't obvious enough already. Harry receives the invisibility cloak at Christmas with a note explaining that it wants belonged to his father, and almost immediately begins using it to explore Hogwarts at night. And during one of these trips, he ends up hiding from filth and snake, stumbles into an unused classroom, and of course discovers the mirror of Error said. The Nimbus 2000. And for one final detail, let's head back to the Quidditch pitch, because buried amongst all of the flying footage, we also get what appears to be our first proper look at Harry's brand new broom, the Nimbus 2000. This becomes an incredibly
important object for Harry during his first year, because after McGonagall witnesses his natural ability on a broom, she arranges for him to receive one so that he can become Grif and new seeker. And while the trailer doesn't exactly stop and announce, look, it's the Nimbus 2000. The broom Harry is running during these Quidditch shots appear to be the new series interpretation of it. Before Hogwarts, Harry barely earns anything at all. Then suddenly he has a wand, an owl, an invisibility cloak, and one of the best racing brooms money can buy. Now, none of these things are particularly important by themselves, but when you add all of them together, I think it shows us that HBO showrunners are taking the project a lot more seriously than some people have given them credit for. The eye for one after seeing all of these trailers are excited for what's to come. As I'll come believe this was just another teaser, I mean, what's the full trailer gonna look like? Let me know what Easter eggs I missed down in the comment section below. Until next time, remember, it does not too to dwell on dreams, and forget to live.
