Warwick Davis, one of the returning characters from the original 'Harry Potter' movies, revealed how the upcoming TV series is different from the big screen feature. The actor who returns to his role as Professor Flitwick called the series "faithful adaptations" of the hit J.K. Rowling books.

In an interview with Times Radio, "I’m working on it at the moment, but I can’t really tell you anything other than we’re retelling those wonderful stories but with more depth and detail than has been seen before,” he said. "They’re very faithful adaptations of the book. We’re obviously telling the same story, so there are similar moments that we’re experiencing as actors on the set. But it’s weird being back in the same studios again, doing it all again, because Leavesden is where we shot the films."

It's worth noting that Davis played Professor Flitwick, a goblin bank teller and the voice of Griphook in 'Harry Potter and the Sorcerer’s Stone'. He appeared in all eight of the movie adaptations. In related news, HBO Chief Casey Bloys revealed that the writing for season 2 was already in the works ahead of the first season's release.

"The plan is to still try and get it — I don’t know if it’s going to be like stop shooting Season 1 on Friday and start Season 2 on Monday. There’ll be a break in there, but we’re going to do whatever we can to not have a huge gap," Bloys told the media during a press conference. "For the kids, obviously, but also for viewers. You know, trying not have massive gaps. It is a big show, lots of special effects, obviously, massive operation, but we’re going to do what we can."

On the cast front,  Dominic McLaughlin stars as the titular wizard. Alastair Stout will play Harry’s best friend Ron Weasley, and Arabella Stanton plays Hermione Granger. Nick Frost as Rubeus Hagrid, John Lithgow as Albus Dumbledore, and Janet McTeer as Professor McGonagall round up the major names. Gardiner and Mark Mylod write and direct, respectively. Francesca Gardiner and Mark Mylod write and direct the series, respectively.

HBO's 'Harry Potter' series is slated to release in 2027. The network has already planned that each season of the show will span one of Rowling’s novels. This would mean seven seasons in total, with work on the second already underway.
