The HBO Max Harry Potter series trailer has arrived with an extended look at HBO’s upcoming television adaptation, revealing Dominic McLaughlin as Harry Potter and showcasing Hogwarts, the Sorting Hat ceremony, Quidditch, magical classes and several familiar characters. The new trailer arrived on September 2, 2026, ahead of the series’ confirmed Christmas 2026 debut.
The series is officially titled Harry Potter and the Philosopher’s Stone for its first season. In the United States, the corresponding book and original movie title uses Harry Potter and the Sorcerer’s Stone. HBO’s adaptation will premiere on HBO and stream exclusively on HBO Max where available.
The latest trailer provides the most extensive preview yet of the new Harry Potter cast and the world they will inhabit. It also confirms that the first season will consist of eight episodes and will adapt the first book in J.K. Rowling’s series.
What the New HBO Max Harry Potter Series Trailer Shows
The newly released footage focuses heavily on Harry’s first year at Hogwarts. It moves from his arrival in the wizarding world to his early experiences as a student at the famous school.
Dominic McLaughlin appears throughout the trailer as Harry, while Alastair Stout plays Ron Weasley and Arabella Stanton portrays Hermione Granger. The three young actors were officially announced as the central trio in May 2025.
Among the most recognizable moments shown are Harry’s introduction to Hogwarts, the Sorting Hat ceremony, magical lessons and early interactions with his classmates and teachers.
The trailer also gives viewers a more substantial look at Hogwarts itself. The Great Hall, classrooms, grounds and other locations appear as Harry begins to understand the world that exists beyond his life with the Dursleys.
The Sorting Ceremony Gets a Major Moment
One of the most recognizable scenes in the trailer is the Sorting Hat ceremony.
Harry, Ron and Hermione are shown entering the Great Hall with the other first-year students. Janet McTeer appears as Professor Minerva McGonagall, while the young students await their Hogwarts houses.
The sequence gives the new cast an opportunity to recreate one of the most important early moments from the first Harry Potter story.
Harry’s concern about his house placement also appears in the footage. The scene establishes the character’s early uncertainty while introducing one of Hogwarts’ most important traditions.
The trailer also shows the trio beginning their lives as Hogwarts students after the sorting ceremony.
Dominic McLaughlin Leads the New Cast
Dominic McLaughlin takes over the role of Harry Potter for HBO’s adaptation.
The actor was selected after an extensive casting search, with HBO announcing McLaughlin alongside Arabella Stanton and Alastair Stout in May 2025. The production described the trio as the new Harry, Hermione and Ron for the television series.
The new trailer provides considerably more footage of McLaughlin than the earliest promotional material. It shows Harry interacting with classmates, teachers and his new friends.
Alastair Stout plays Ron Weasley, while Arabella Stanton plays Hermione Granger. Their characters form the central friendship at the heart of Harry’s first year.
The trailer gives viewers a chance to see the three performers together in several familiar Hogwarts settings.
Paapa Essiedu Appears as Severus Snape
Paapa Essiedu receives prominent attention in the new footage as Severus Snape.
The trailer shows Snape during Harry’s early Hogwarts education, including a Potions classroom sequence. His relationship with Harry immediately carries the tension familiar from the original story.
Essiedu is part of HBO’s confirmed adult cast, which also includes John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall and Nick Frost as Rubeus Hagrid.
The new footage gives each of these established Hogwarts figures a clearer presence than the first teaser released in March.
John Lithgow’s Dumbledore Gets More Screen Time
John Lithgow appears as Albus Dumbledore, giving viewers another substantial look at HBO’s interpretation of the Hogwarts headmaster.
Dumbledore remains one of the most important figures in Harry’s first year. The trailer places Lithgow among the professors and students during Harry’s introduction to Hogwarts.
His appearance is part of a broader effort by HBO to show the school and its staff in greater detail across the television format.
Hagrid and Other Familiar Characters Return
Nick Frost appears as Rubeus Hagrid, the Hogwarts groundskeeper who becomes an important friend to Harry.
The trailer also includes several other recognizable characters from the first story. The confirmed cast includes Rory Wilmot as Neville Longbottom and Lox Pratt as Draco Malfoy.
Warwick Davis also returns to the Wizarding World, this time reprising the role of Professor Filius Flitwick. Davis previously played Flitwick in the original Harry Potter film series. HBO confirmed his return in 2025.
Additional confirmed cast members include Daniel Rigby as Vernon Dursley, Bel Powley as Petunia Dursley and Amos Kitson as Dudley Dursley.
Quidditch Takes Flight in the New Trailer
Quidditch is another major feature of the new footage.
The trailer shows Harry developing an interest in the wizarding sport and taking to the air on a broomstick. The sequence provides one of the clearest looks yet at how HBO is bringing the sport into the television adaptation.
The Quidditch material is particularly significant because Harry’s involvement in the sport becomes an important part of his first year at Hogwarts.
The new footage also shows Harry and his friends exploring other aspects of magical life, reinforcing the scale of the world being created for the series.
The Invisibility Cloak Appears
Another recognizable object featured in the trailer is Harry’s invisibility cloak.
The cloak plays an important role in the first story, allowing Harry to explore Hogwarts after hours while attempting to remain unseen.
Its appearance in the trailer confirms that HBO is incorporating familiar book elements into the first season rather than limiting the adaptation to the most prominent movie scenes. Variety also highlighted the cloak among the trailer’s major reveals.
The trailer additionally features the mystery surrounding the Philosopher’s Stone, which drives the story toward its central conflict.
The Troll Encounter Is Also Featured
The new footage includes the famous dungeon troll sequence.
The encounter is one of the key events that brings Harry, Ron and Hermione closer together during their first year.
The trailer shows the trio facing the dangerous creature, giving viewers another direct look at how the HBO adaptation is recreating moments that audiences already know from the first Harry Potter story.
The sequence also reinforces the importance of friendship to the first season. Harry, Ron and Hermione gradually become a team as they encounter increasingly serious dangers inside Hogwarts.
Eight Episodes Are Planned for Season 1
HBO has confirmed that the first season will consist of eight episodes.
The season is titled Harry Potter and the Philosopher’s Stone and will adapt the first book. HBO’s official announcement describes the series as a faithful adaptation of Rowling’s books.
The eight-episode format gives the television adaptation more room than a single feature film to develop Harry’s first year.
That additional episode space allows the story to spend more time with characters, Hogwarts classes and events surrounding Harry’s discovery of the wizarding world.
The new trailer reflects that broader approach by showing a variety of scenes from throughout Harry’s first year.
When Will the Harry Potter HBO Series Premiere?
The first season is scheduled to debut on Christmas Day 2026.
HBO confirmed the Christmas 2026 premiere when it released the first official teaser in March. The company has continued to identify Christmas 2026 as the launch window in its latest promotional material.
For U.S. viewers, the series will be available through HBO and HBO Max. HBO’s current official materials describe HBO Max as the exclusive streaming destination where the service is available.
The Christmas launch gives the series a major holiday-season debut, with HBO positioning the return to Hogwarts as one of its key entertainment events for the end of 2026.
Who Is Making the New Harry Potter Series?
Francesca Gardiner serves as showrunner, writer and executive producer. Mark Mylod will executive produce and direct multiple episodes.
The series is being produced by HBO in association with Brontë Film and TV and Warner Bros. Television. J.K. Rowling serves as an executive producer alongside Neil Blair and Ruth Kenley-Letts of Brontë Film and TV, as well as David Heyman of Heyday Films.
Production began at Warner Bros. Studios Leavesden in the United Kingdom in 2025. HBO originally announced the project in 2023 as its first scripted Harry Potter television series.
How the New Trailer Differs From the First Teaser
HBO released the first official teaser in March 2026. That initial footage introduced Dominic McLaughlin as Harry and established the Christmas 2026 premiere.
The newer trailer goes considerably further.
Instead of concentrating primarily on Harry’s life before Hogwarts, the latest footage spends much more time inside the school. Viewers see the Sorting Hat, Quidditch, magical lessons, professors, Hogwarts locations and several major story moments.
The change gives audiences a clearer understanding of the television series itself.
It also demonstrates how the production is moving beyond a simple introduction to Harry and toward the complete story of his first year at Hogwarts.
The Trailer Has Already Set a Major HBO Record
Interest in the new adaptation was already enormous before the latest footage arrived.
HBO reported that its March 2026 official trailer generated more than 277 million organic views across platforms during its first 48 hours. HBO said that made it the most-watched trailer in HBO and HBO Max history at the time, exceeding the previous record by more than double.
The latest trailer now gives that existing audience a much deeper look at the series.
With the Christmas premiere approaching, HBO has moved from introducing the new cast to showcasing the actual Hogwarts experience viewers can expect from the first season.
