Warner Bros. Discovery’s new Harry Potter series for HBO and HBO Max will premiere in 2027, the company announced. Production has started on the show in the UK.

The show is set to be a “faithful adaptation of the beloved Harry Potter books,” according to WBD, and the original Harry Potter movies will still be available on HBO Max. When the show was first announced in 2023, WBD said it would be a “decade-long series.”

WBD also released an on-set picture of Dominic McLaughlin, who is playing Harry Potter, in his Hogwarts robes. Newcomers Alastair Stout and Arabella Stanton will play Ron Weasley and Hermione Granger.

The company announced some new cast members, too: Rory Wilmot will play Neville Longbottom, Amos Kitson will play Dudley Dursley, Louise Brealey will play Madam Rolanda Hooch, and Anton Lesser (who you might recognize as Lio Partagaz from Andor) will play Garrick Ollivander. WBD has trickled out other cast announcements over the past few months, including that John Lithgow will play Dumbledore.

Harry Potter author J.K. Rowling, who has been heavily criticized for hurtful comments toward the transgender community, is serving as an executive producer on the series.
