To celebrate today's "Back to Hogwarts" celebrations, HBO's Harry Potter TV series has confirmed (via SFFGazette.com) that Warwick Davis will reprise his film role as Professor Filius Flitwick, marking his return to the Wizarding World. 

The series has also cast more Hogwarts students, with Elijah Oshin as Dean Thomas, Finn Stephens as Vincent Crabbe, and William Nash as Gregory Goyle. The school's staff has added to its ranks, with Sirine Saba as Professor Pomona Sprout, Richard Durden as Professor Cuthbert Binns, and Bríd Brennan as Madam Poppy Pomfrey.

Finally, Joker star Leigh Gill will take on the role of Gringotts Bank's Griphook, a role Davis previously took on in the Harry Potter movies. 

With that, the Harry Potter cast is nearly complete. A few key roles still need to be filled—the biggest is Lord Voldemort, though the plan is reportedly for him to be unveiled when the show airs—but HBO has put together an impressive ensemble that, inevitably, will be compared to what we saw in theaters from 2001 to 2011.

Does Davis' return mean we'll see more actors reprise their roles from the movies in Harry Potter when it arrives on HBO in 2027? This does feel a little like stunt casting, and is likely a one-off, but the Willow star is beloved among sci-fi and fantasy fans, so there are unlikely to be too many grumblings around his comeback. 

Taking place annually on September 1, "Back to Hogwarts" is a global celebration of all things Harry Potter where fans mark the iconic return to Hogwarts School of Witchcraft and Wizardry.

Weigh in with your thoughts on these latest additions to the Harry Potter cast in the comments section below. 

Dominic McLaughlin has been cast in the role of Harry Potter, with Arabella Stanton as Hermione Granger, and Alastair Stout as Ron Weasley.

Joining them will be Lox Pratt as Draco Malfoy, Rory Wilmot as Neville Longbottom, Tristan Harland as Fred Weasley, Gabriel Harland as George Weasley, Ruari Spooner as Percy Weasley, Gracie Cochrane as Ginny Weasley, Leo Earley as Seamus Finnigan, Alessia Leoni as Parvati Patil, Sienna Moosah as Lavender Brown, and Amos Kitson as Dudley Dursley.

Harry Potter's adult cast includes John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall, Paapa Essiedu as Severus Snape, Nick Frost as Rubeus Hagrid, Luke Thallon as Quirinus Quirrell, Louise Brealey as Madam Rolanda Hooch, and Paul Whitehouse as Argus Filch.

Joining them will be Katherine Parkinson as Molly Weasley, Johnny Flynn as Lucius Malfoy, Bel Powley as Petunia Dursley, Daniel Rigby as Vernon Dursley, Anton Lesser as Garrick Ollivander, and Bertie Carvel as Cornelius Fudge.

The series will be a faithful adaptation of the beloved Harry Potter book series by author and executive producer J.K. Rowling and will feature an exciting and talented cast to lead a new generation of fandom, full of the fantastic detail and much-loved characters Harry Potter fans have adored for over 25 years.

The series is written and executive-produced by Francesca Gardiner. Mark Mylod will executive produce and direct multiple episodes of the series for HBO in association with Brontë Film and TV and Warner Bros. Television. The series is executive produced by J.K. Rowling, Neil Blair, and Ruth Kenley-Letts of Brontë Film and TV, and David Heyman of Heyday Films.

Harry Potter premieres on HBO in 2027.

"Warwick Davis will reprise his film role as Professor Filius Flitwick, marking his return to the Wizarding World."

Did he first remember to get Peter Dinklage's permission I wonder??? 🤔

@SuperiorHeckler - He'd have to, given Dinklage is the king of the little people 😁

Makes this show even more pointless. What's the point?

@WalletsClosed - To create a version more in line with the books, which the films weren’t. “The Goblet of Fire” film wasn’t even close to the book, which is sad since it was one of the best in the series.

Cool!!.

I’m honestly fine with Warwick Davis reprising his role as Professor Flitwick from the films in the show since it’s just a nice homage & connection to the former (hopefully though we don’t get anymore old cast members)…

I do wonder how Flitwick will look in the show though since he has had 2 distinct looks in the films?:

Anyway , the rest look fine and seem to fit their roles!!.

Those suggesting that the series isn’t different enough don’t really understand the majority of the HP fandom. They don’t want “different” as much as they want a complete adaptation closer to the books. The films, especially number three onward, cut so many significant subplots and many fan-favorite moments in favor of a shorter runtime. It’s telling when the Order of the Phoenix film is the shortest in the series while being comfortably the longest book. For context, the first movie is almost 20 minutes longer than the fifth, despite the book being less than 1/3 of the length. And a lot of what was adapted took some big creative liberties.

The HBO series isn’t supposed to be this huge departure from the movies. The entire premise is “we will adapt the stuff the movies didn’t have time to get to”.

Could've had potential as an interesting, more book accurate take but the Snape casting kills it in the crib unfortunately
