HBO’s Harry Potter TV Series Scores Warwick Davis to Bring Back Beloved Professor Flitwick

Alright, Potterheads and casual muggles alike, brace yourselves. Just when you thought the Wizarding World had been milked dry for every last spell and snitch, HBO goes and drops a mega-bombshell: Warwick Davis is reprising his role as Professor Filius Flitwick in the new Harry Potter TV series. Yes, that Warwick Davis, the wizard who schooled us all in charms, and who somehow managed to pull double duty as both Flitwick and the goblin Griphook back in the day.

Spoiler alert: no goblin gig this time. But why mess with a winning formula? Let’s unpack this magical mystery tour and why this casting choice is basically wizard-level genius.

Warwick Davis Is Back: The Truth About Nostalgia

Look, Hollywood loves nostalgia like Dobby loves socks. But when it comes to reboots, nostalgia can either be a warm, fuzzy Patronus or a cringe-worthy Dementor sucking the life out of your favorite story. HBO wisely chose the former by bringing Warwick Davis back to reprise Flitwick. This isn’t just a cameo to get clicks, this is a full-on "welcome home, mate" moment.

Warwick Davis has been part of the Harry Potter family for over two decades. From 2001’s Sorcerer’s Stone all the way through Deathly Hallows Part 2, he was the go-to guy for all things magically charming. Bringing him back anchors the series in the original magic, while reminding us all that some things don’t need fixing.

What We Actually Know About HBO’s Harry Potter Series (Besides Warwick)

So here’s the deal: HBO and Warner Bros. are taking their sweet time and rightfully so, with this project. The series is set to cover all seven books, one season per book. That means no more cramming entire novels into two-and-a-half-hour movies with scenes hacked off like a rogue spell gone wrong.

Filming kicked off in July 2025 at Leavesden Studios, the very same lot that birthed the original films. That alone should calm your cranky inner critic. It means the creators want to maintain the authentic Hogwarts vibe, from the cobblestone halls to the dusty potions classrooms.

The cast is a juicy mix of new faces and seasoned actors, including:

• John Lithgow as Dumbledore—because the world clearly needs another Dumbledore, and if anyone can pull off eccentric and brilliant, it’s Lithgow.

• Nick Frost as Hagrid—a casting choice that makes you say “Oh, that actually works.”

• Paapa Essiedu as Severus Snape—which might cause a few gasps, but hey, maybe he’s got the brooding dark wizard vibe down cold.

• And then there’s the young trio: Dominic McLaughlin (Harry), Arabella Stanton (Hermione), and Alastair Stout (Ron). Fresh faces, so be gentle.

Warwick Davis’s Flitwick: Big Personality

In the original films, Flitwick was kind of a background character, cute, quirky, and always ready to cast a charm or two. But now that we’re dealing with a TV series, there’s room to actually explore the professor’s story. Davis himself hinted that this feels like a “homecoming,” so expect him to bring a whole lot of heart and maybe even some surprises to a role that was previously relegated to quick classroom scenes and a bit of comic relief.

No longer just a background flicker, Flitwick might finally get the character depth he deserves. After all, who else is going to teach all those complicated charms? If HBO plays their cards right, Flitwick could become a fan favorite all over again, or for the first time.

Why This Series Could Actually Work (Don’t Roll Your Eyes Yet)

Look, it’s easy to be cynical about any Harry Potter project announced after the original movies. We’ve had everything from cursed video games to stage plays. But HBO is not messing around. The showrunner Francesca Gardiner is steering this ship, and Mark Mylod, who has serious chops from shows like Succession, is directing multiple episodes. These are not people who want to phone it in.

Plus, the plan to dedicate an entire season to each book means no more rushed plotlines or weird character cuts. Want to see Hogwarts classes? They got time for that. Want to linger on those deliciously awkward teen moments? Check. More spells, more politics, more drama, the series is promising a slow-burn feast for fans who’ve been craving depth for years.

The One Big Question: Will This Be Magical or Just Another Dud?

Warwick Davis’s involvement feels like the producers saying, “We get it. We respect the fans.” It’s a smart move, but the rest of the series has a lot to live up to. The original films had charm, pacing, and that unique mix of darkness and whimsy that made the books so beloved. HBO’s adaptation better capture that or risk getting lost in a sea of streaming content.

For now, the return of Davis as Professor Flitwick is a beacon of hope and maybe a little bit of fan service we’re totally here for. He’s the first original cast member officially confirmed, which sets the tone for a series that wants to honor its roots without getting stuck in the past.

Wrapping It Up: Expect Magic, Mystery, and a Dash of Snark

With Warwick Davis back as Professor Filius Flitwick, authentic locations, and a commitment to faithful storytelling, this show could be something interesting. So, dust off your robes and prepare your best sarcastic quips because Hogwarts is reopening.

Got hot takes on the casting or want to speculate on which Hogwarts house Warwick Davis’s Flitwick will really belong to? Drop your thoughts—because nothing in the Wizarding World is ever without a little drama.
