Potterheads, pack your bags, grab your wands, and head to Platform 9¾. It’s almost time to return to Hogwarts for a new semester. 

On Wednesday, HBO unveiled the first trailer for the Harry Potter reboot, giving fans a first real look at J.K. Rowling’s wizarding world and the new golden trio. 

The trailer also confirmed the release date, which may be the reboot’s most welcome update after months of backlash and casting controversies.

As fans await the new iteration of the beloved books, many are looking for more details, including the cast and plot.

The first season of Harry Potter, subtitled The Philosopher’s Stone, will premiere on December 25, 2026. The series will air on HBO and stream on HBO Max.

The first season is expected to comprise eight episodes. The series was first announced in April 2023 and has received backlash from fans for various reasons, including Rowling’s involvement as an executive producer and some casting choices.

However, the Christmas release date might be the show’s most promising update, as the holiday season plays into the nostalgia surrounding the source material. 

In the books, Christmas typically marks the end of term at Hogwarts and leads into a two-week winter break. Harry’s choice to spend his first break at Hogwarts directly ties into the narrative of The Philosopher’s Stone, making the release timing perfect for fans old and new. 

The new Harry Potter cast is filled with fresh faces

The reboot will feature an entirely new cast, separate from the actors who previously played the iconic roles in the film adaptation. 

The golden trio of Harry Potter, Hermione Granger, and Ron Weasley will be portrayed by Dominic McLaughlin, Alastair Stout, and Arabella Stanton, respectively.

The rest of the main cast is mostly comprised of Hogwarts teachers, including: 

Additionally, Lox Pratt plays Draco Malfoy, a Slytherin student and Harry’s rival. Bel Powley and Daniel Rigby appear as Harry’s relatives, Aunt Petunia Dursley and Uncle Vernon Dursley. 

Essiedu’s casting received particular backlash, with fans accusing the makers of needlessly race-bending the character previously played by the late Alan Rickman.  

Which books will the Harry Potter reboot adapt?

As the title suggests, the first season will adapt Rowling’s debut novel, which was released in 1997. 

The story introduces viewers to the world of Hogwarts, taking place during Harry’s first year at the school. During this time, Harry and his friends investigate the mysterious Philosopher’s Stone, leading them to dark secrets of the wizarding world. 

An official logline for the first installment reads:

“There is nothing special about Harry Potter – at least that’s what his Aunt Petunia always says. On his 11th birthday, a letter of admittance to Hogwarts School of Witchcraft and Wizardry opens up a hidden world for Harry: one of fun, friendship, and magic. But with this new adventure comes great risk as Harry is forced to face a dangerous enemy from his past.”

As previously mentioned, HBO released the first trailer on March 25. However, it received mixed reactions on social media platforms like X.

Some viewers praised the new costumes, sets, and the show’s production values. The performances of Frost as Hagrid and Powley as Aunt Petunia also received positive reactions.

“This looks unexpectedly good,” a fan said. 

Another commented, “This looks fu*king peak bro, this show was a great idea in my opinion.”

However, others deemed the reboot entirely “unnecessary,” arguing that the original cast was much better in their respective roles. Essiedu’s Snape received the brunt of the fan backlash.  

“What is the point in a reboot if it’s basically the same thing?” one user wrote. 

A second said, “How tf are they going to race swap some of the most important characters in the story. This show is over before it even begins.”

The Harry Potter movies are available to stream on HBO Max.
