- Quick Answer: HBO's Harry Potter series premieres in late 2026, featuring book-accurate scenes like Harry's school bullying and a nighttime Hogwarts Express arrival.
HBO has finally released the first teaser for its highly anticipated Harry Potter reboot, and it silences any doubts fans may have about the TV adaptation of J.K. Rowling’s beloved book series.
Promising to be a faithful adaptation of the novels, the clip reveals parts of the story that weren’t in the original books or movies.
Now that we’ve had a good look at the upcoming series, here’s a breakdown of all the book and movie changes the Harry Potter reboot trailer reveals.
Harry Potter’s Life with the Dursleys
Fans who have seen the Harry Potter movie series know that the Dursleys gave Harry a hard time while he was still living with them, but the TV version reveals even more, with additional scenes from No. 4 Privet Drive.
As the trailer shows, viewers may get a deeper look at Harry’s life with the Dursleys before his journey to Hogwarts begins, including a clip of Aunt Petunia cutting Harry’s hair, making the series feel more grounded and realistic.
Harry Potter Being Bullied at School
The Dursleys aren’t the only ones making Harry Potter’s life difficult in the suburban city. He also struggles at school, facing bullying, which will be depicted in the HBO reboot.
Several shots from the trailer show Dudley Dursley and his friends tormenting Harry at school, scenes that appear in the books but were never shown in the movies.
This also hints at Dudley’s character arc being explored more fully, as the films primarily focused on his life at home with his parents.
The Hogwarts Letter
As Petunia stresses to Harry that there’s nothing special about him, a Hogwarts letter arrives, signaling the start of his true adventure.
The writing is elaborate, giving complete details of his room – the famous “cupboard under the stairs.”
Since the letter has no postage stamp, Harry assumes it was hand-delivered, unaware that it is all magic.
Harry Potter Riding the Train with Hagrid
In the first Harry Potter movie, The Sorcerer’s Stone, Hagrid brings Harry from the hut on the rock in the sea to London. There, they visit Diagon Alley to buy school supplies, including Hedwig.
In contrast, the HBO series trailer shows Harry and Hagrid riding a train in the London Underground. During the journey, Hagrid shares more about Harry’s parents as they make their way into the wizarding world.
The Hogwarts Express at Night
True to the books, the Harry Potter trailer shows a stunning shot of the Hogwarts Express traveling at night, reflecting that this is the only time the train actually arrives.
In the movies, however, the Hogwarts Express is often depicted traveling during the daytime. It departs from Platform 9¾ at 11:00 a.m. on September 1st and continues its journey throughout the day.
A Different Severus Snape
A different Severus Snape will appear in HBO’s Harry Potter, distinct from Alan Rickman’s iconic portrayal of the Potions Master.
In a brief scene in the trailer, he uses Lumos to cast light in a dark hallway, likely from the moment he nearly discovers Harry under his invisibility cloak.
It seems HBO is fully aware that no one can match Rickman’s legendary performance, so the series takes a different approach in bringing the Hogwarts professor to life on TV.
Harry and Ron’s First Meeting
Harry Potter and Ron Weasley’s first meeting on the Hogwarts Express in the movie is a heartwarming moment of strangers becoming close friends.
Ron kindly asks to sit in Harry’s compartment, introduces himself, shows him his pet rat Scabbers, and even asks to see Harry’s scar.
In the HBO series, however, Ron asks Harry if he is really the famous Harry Potter and makes a playful lightning-blast shape on his forehead, referencing his iconic scar. It may seem a bit awkward, but it marks the promising start of a lifelong friendship.
Surprisingly, despite the earlier announcement that HBO’s Harry Potter reboot would be released in 2027, fans got an early Christmas gift: the series is now set to premiere during the 2026 holiday season.
