What HBO’s Harry Potter series will mean for LEGO in 2027: our predictions

The first trailer for HBO’s Harry Potter series is here, confirming a premiere date of Christmas 2026 – but what will it mean for LEGO Harry Potter in 2027 and beyond?

The LEGO Harry Potter theme has so far stuck pretty closely to the movies, occasionally dipping into the books for an obscure character pick while still basing designs on the aesthetics of the original adaptations. But a new era of the Wizarding World is upon us thanks to HBO’s TV series, which kicks off this Christmas with a season dedicated to Harry Potter and the Philosopher’s Stone.

Are we staring down the magical barrel of a new era of LEGO Harry Potter as a result? Let’s pick apart the possibilities, gaze into our crystal balls and try to decipher the tea leaves to figure out what’s next for the Wizarding World…

HBO go or no?

Probably the first and most relevant consideration is whether the LEGO Group will tackle the HBO series at all, or continue to focus on the original movies. And this is an easy one to predict: yes, the series will influence the direction of the LEGO sets, if only because it’s where the attention of IP partner Warner Bros. will be for the foreseeable future, marketing and all. Exactly how it will inform merchandise is the real thing to unpack here.

Back to the beginning

When LEGO Harry Potter returned anew in 2018, it kicked off with a wave of sets dedicated to the Philosopher’s Stone and the Chamber of Secrets, then progressed chronologically through the series right up to the Half-Blood Prince. It took a while for the LEGO Group to finally embrace the darker chapters of the Deathly Hallows, and in the meantime the theme took a broader scattershot approach to iconic scenes, much like Star Wars.

It now plays out like a greatest hits of the franchise, serving up a variety of sets from across the movies with each wave. But with Harry Potter and the Philosopher’s Stone (the TV show) now due to premiere at the end of 2026, an entire wave focusing on the events of the first entry in the series feels nailed on for January 2027.

And with the series set to go into greater detail than the movie and presumably stick even closer to the source material (owing to its longer runtime), there’s every chance we could then see LEGO sets based on scenes that have never been attempted before in bricks, such as Harry’s run-in with a snake at the zoo or the first meeting with Voldemort in the Forbidden Forest.

At the same time, the door will be open to revisit scenes we’ve not seen in a while, or only as part of larger Hogwarts sets, that otherwise might not have justified a standalone release in a regular LEGO Harry Potter assortment. The troll encounter in the girls’ bathroom, Gryffindor common room and the chambers through which the trio progress on their way to find Quirrell spring to mind.

Oh, and it would be neat to finally get back to LEGO Quidditch…

Meet the new boss, same as the old boss

So the focus of LEGO Harry Potter might shift in 2027: what about the aesthetics? Would those sets actually look any different to what’s come before? This is a trickier one to predict, because from the trailer it looks like the HBO series is – as expected – hewing pretty closely to the aesthetics of the original movies. There are maybe only so many ways to depict the castle, the students’ robes, and so on, and it’s fair to say the films cracked most of the right nuts the first time round anyway.

And then there are the more cynical financial considerations: Warner Bros. has an entire Harry Potter theme park area designed around the aesthetic of the movies, so you can imagine it wants to make Hogwarts Castle, Diagon Alley and all the merchandise cross-compatible between movies and series. But when you get down to the level of LEGO sets, that means not much might change at all.

Yes, we’ve got an entirely different cast here, but most of these characters will likely look much the same when boiled down to minifigures (not least because their costumes are pretty similar, particularly Hagrid). There are a handful of exceptions that it will be interesting to see if the LEGO Group recognises, such as Professor Snape (now played by Paapa Essiedu), but by and large it’s difficult to imagine much change in the minifigure department.

And as for the wider sets? Well, we’ve yet to see much in the way of Hogwarts’ exterior from the trailer, but aside from slightly muggier colour grading the rest of HBO’s Wizarding World doesn’t feel too far away from the movies. Don’t hold your breath for new Hogwarts sets that switch out tan castle walls for grey, for example, or a Hogwarts Express in anything other than red.

In short, you can probably expect your new LEGO Harry Potter HBO sets to sit just fine on your shelf next to your original builds. The real question is… what does it mean for the current modular Hogwarts system?

Hoggy Warty Hogwarts

The ‘most detailed Hogwarts ever’ kicked off in 2024 with 76435 Hogwarts Castle: The Great Hall, which is retiring in July this year. Plenty of other add-ons have come and gone since, with another flagship section rumoured for release this summer. But will that be the final instalment in this current modular setup? And if so, was that always the plan from day one, or is it a consequence of the HBO series arriving sooner than any of us could perhaps have anticipated?

These are all questions for which we don’t have concrete answers right now, but keeping in mind that the aesthetic of Hogwarts potentially isn’t changing much, it wouldn’t be inconceivable to see the LEGO Harry Potter team merging what might otherwise be branching paths. New Hogwarts sections could fit into this school while mirroring the events of the TV show, for example.

Another possibility is that the theme splits into two distinct categories: sets based on the movies and sets based on the show, so that Hogwarts can keep going while the focus remains elsewhere. That scenario would allow the LEGO Group and Warner Bros. to cater to every fanbase simultaneously, but could potentially feel a little noncommittal where the new show is concerned, so it’s probably not very likely.

Enter the Hall of Prophecy

So, with all that in mind, it’s time to make some more concrete predictions. Here are our best guesses for what to expect from next year…

• LEGO Harry Potter will adapt the new HBO series
• We’ll see a full wave of Philosopher’s Stone sets in January that go bigger on key scenes
• The sets won’t look much different to the current range
• We’ll continue to get a wide variety of sets later in 2027, including buildable characters and objects

All of that is of course just our speculation, but it’ll be interesting to see how much of it we get right. Feel free to share your predictions for the future of LEGO Harry Potter in the comments.
