Who is starring in the Harry Potter TV series?
HBO Max has revealed the names of most of its cast members and has now released a whole host of official photos to tease the series.
On March 24, the streaming giant took to social media to release a photo of the back of Harry in his Gryffindor Quidditch robe, with his broomstick in hand.
It was the second photo of Dominic McLaughlin, 11, who is starring as Harry Potter, that was revealed to the public. HBO initially released a photo of him dressed as the titular character in his wizard robes and with his famous scar in July. His casting was announced in May 2025.
Just hours later, a trailer was released, giving fans an insight into the magical action they can expect from the series.
It gave a first look as Bel Powley as Aunt Petunia and showed Harry’s school days before he set off for Hogwarts with Hagrid (Nick Frost).
Of course, the moment Harry gets his iconic Hogwarts letter is revealed, as well as the moment he meets Hermione (Arabella Stanton) and Ron (Alastair Stout) on the Hogwarts Express.
Scenes from Hogwarts showed John Lithgow as Dumbledore, Paapa Essiedu as Severus Snape and Lox Pratt as Harry’s nemesis, Draco Malfoy.
Harry was also shown heading out to the Quidditch pitch for the first time as his magical story began.
At the end of the trailer, the release date was also revealed – Christmas 2026!
