Harry Potter trailer: HBO Max series teaser and release date - see main characters including Ron, Hermione and Hagrid

It’s the moment Harry Potter fans have been waiting for - the teaser trailer for the new HBO Max TV series has dropped introducing all the main characters - here’s when you can watch it.

Muggles and wizards unite - a trailer has been released for the eagerly-anticipated new Harry Potter TV series. The preview, which confirms the show, based on the bestselling books by JK Rowling, will hit screens at Christmas on HBO Max, shows the young wizard with his friends Hermione and Ron as they travel on the Hogwarts Express.

Opening with scenes of Harry in the home he shares with his muggle aunt and uncle, his aunt Petunia – played by Bel Powley – tells him: “You think you’re something special? There is nothing special about you.”

The trailer then cuts to Harry, played by young actor Dominic McLaughlin, at a railway station with friendly groundskeeper Rubeus Hagrid, played by Nick Frost. Harry is also seen running with a trolley laden with suitcases towards Platform 9 and 3/4, before a shot of the Hogwarts Express pulling into a station.

Harry is shown looking on in awe after arriving at Hogwarts, and walking on to the quidditch pitch, and having a snowball fight with other pupils. It also briefly shows a delighted Hagrid lying on his back on the ground making snow angels.

Set to rousing music, which builds until the last scene, viewers finally see Harry, Hermoine and Ron on the Hogwarts Express at the end of the trailer. Ron, played by Alastair Stout, asks: “Are you really Harry Potter?”

Harry shyly nods, leading Ron to makes a ‘mind blown’ sign with his fingers on his forehead, perhaps in recognition of the young wizard’s famous scar.

The first season of the HBO show was adapted from JK Rowling’s first novel, Harry Potter And The Philosopher’s Stone. Further seasons will feature her other novels, with Rowling acting as an executive producer.

Hermoine is played by Arabella Stanton after a casting call saw around 32,000 children audition for the three lead roles, with the team reviewing up to 1,000 tapes a day.

Also among the cast will be Paapa Essiedu as Professor Severus Snape and US star John Lithgow as Hogwarts headmaster Professor Albus Dumbledore.

Ozark actress Janet McTeer will star as Professor Minerva McGonagall, British stage actor Luke Thallon will play the first book’s main antagonist Quirinus Quirrell, and comedian Paul Whitehouse will play the magic-less Hogwarts School of Witchcraft And Wizardry caretaker Argus Filch. Elsewhere, Warwick Davis will return to Hogwarts to reprise his film role as Professor Filius Flitwick.

The trailer was released on YouTube on Wednesday evening and has already been watched millions of times as fans await the latest Harry Potter franchise to land.
