- Quick Answer: The documentary introduces Dominic McLaughlin as Harry Potter and showcases faithful book-to-screen adaptations, including massive immersive sets and mechanical creatures, ahead of the December premiere.
Before the big premiere of HBO’s Harry Potter reboot in December 2026, the network released a documentary titled Finding Harry Potter: The Craft Behind the Magic, which takes viewers behind the scenes of the highly anticipated TV adaptation of J.K. Rowling’s beloved novels.
The 30-minute special doesn’t just offer a sneak peek at what’s coming. It also features the creative vision behind the show, the massive craftsmanship involved, and the storytelling ambitions driving one of the most anticipated TV series of the decade.
From a record-breaking casting process to sprawling set and production design, here are the five major insights Finding Harry Potter revealed about HBO’s magical new series.
Record‑Breaking, Immense Casting Process
Finding Harry Potter proves that casting a new generation of the Golden Trio was no easy task.
Daniel Radcliffe, Rupert Grint, and Emma Watson are now inseparable from their roles as Harry Potter, Ron Weasley, and Hermione Granger, so the casting directors were extremely meticulous in selecting the young actors to carry these iconic characters forward.
Over 40,000 auditions were held across the UK to find the perfect young stars. Alastair Stout was the first to be cast as Ron, followed by Arabelle Stanton as Hermione.
Dominic McLaughlin won the directors’ hearts as the new Harry thanks to his confidence, engaging personality, and a brilliantly performed original poem.
Massive, Immersive Sets and Production Design
If the Harry Potter movies featured sprawling sets, Finding Harry Potter revealed that the HBO revival will take it even further, with massive, immersive sets and highly detailed production design.
From Hogwarts classrooms and dormitories to Diagon Alley and the castle grounds, the sets are more expansive than ever before.
Unlike the isolated backdrops of the films, the TV series adopts a world-building approach, using camera movement and storytelling to allow scenes to flow naturally from one space to another.
Extensive Practical Effects and Animatronics
Sure, CGI is common nowadays, but HBO relies heavily on practical effects and animatronics.
The network’s creature designers, many of whom worked on the films, created real, mechanical versions of magical animals and beings, including animatronic owls, Scabbers the rat, and quirky creatures like fire-breathing toads.
Book Details Cut from the Movies
If there’s one thing book fans can look forward to in HBO’s Harry Potter reboot, it’s the show’s focus on restoring details cut from the films.
Scenes that didn’t make it into the movies due to runtime limitations will finally appear.
One notable example is when Ron’s pet rat, Scabbers, defends sweets from Goyle–a scene absent from the films. From the looks of it, HBO is keeping its promise to make the revival faithful to the books.
Best Looks at Major Hogwarts Professors
Fans finally got their best looks at major Hogwarts professors in Finding Harry Potter, from Dumbledore to Snape to McGonagall.
Paapa Essiedu, who takes over the role of Professor Snape from Alan Rickman, shared how meaningful it is to portray such an iconic character.
While John Lithgow and Janet McTeer, playing Dumbledore and McGonagall, appeared briefly, they discussed the experience of bringing these beloved characters to life for a new era.
Nick Frost, who now plays Hagrid, also narrates the special, hinting at how exciting the reboot will be with both veteran actors and new stars working together.
Finding Harry: The Craft Behind the Magic is available to stream on Max, while HBO’s Harry Potter reboot is slated to release in December 2026.
