Harry Potter Trailer: First trailer for HBO's Harry Potter series promises 'a new era of Hogwarts'

After teasing followers on social media with a glimpse of Scottish actor Dominic McLaughlin as Harry in his quidditch uniform last night, the official trailer for the reboot is now here with season one confirmed to be named after the first book, Harry Potter and the Philosopher’s Stone.

The show, which is set to be released late this year, will reimagine J.K Rowling’s bestselling fantasy series for a new generation, following the hugely successful film series.

McLaughlin, who will take over from Daniel Radcliffe as the titular character, was cast in the lead role following an open casting call for actors from the UK and Ireland in 2024. He will star alongside Arabella Stanton, who will make her on screen debut as Hermione, and Alastair Stout who will play Ron - all three of whom can been seen throughout the first look.

Arriving just in time for the launch of HBO Max in the UK, other actors who appear in the Harry Potter trailer include Nick Frost, Paapa Essiedu, John Lithgow, and Bel Powley.

What does the Harry Potter trailer reveal?

The trailer opens with Petunia Dursley berating Harry that he his a “normal boy”, and that he must start acting like one. We see Harry being thrown into the cupboard under the stairs, with scenes from his life pre-Hogwarts - bullying, his aunt’s haircuts and more - shown.

Then, just as she tells Harry that there is “nothing special” about him, we see the arrival of a letter with no stamp. Mysterious. We also get a look at Frost as Hagrid as he leads Harry to the Wizarding World and sharing some information about his parents.

The trailer also reveals that the show will be set in the nineties based on the fashion, with very brief appearances from supporting characters such as Professor McGonagall, Professor Sprout, Professor Snape, Olivander, Mrs Weasley and more.

Notably, we also see Harry with Ron and Hermione at various points of the trailer - including their first meeting on the Hogwarts Express.
