Harry Potter is coming on Christmas Day, and HBO’s boss has seen every episode: ‘It is great’

If you thought the film series was where the story would end, well, think again: HBO is pulling out all the stops with a sprawling, prestige-telly adaptation of the Harry Potter novels, and if you believe the network’s head honcho, it’s shaping up rather nicely. The studio is promising a proper long-form reboot, aiming to dig into bits of the Wizarding World that never got their due on the big screen. It's all coming a lot sooner than people reckon, too.

Full cast, early verdicts

Let’s start with the most immediate news: Season 1 has already finished shooting. HBO charged ahead with production straight after landing their main trio — Dominic McLaughlin as Harry, Alastair Stout as Ron, and Arabella Stanton as Hermione. There’s also a mix of familiar faces for the grown-ups, including John Lithgow (Dumbledore), Janet McTeer (McGonagall), Nick Frost (Hagrid), and Paapa Essiedu (Snape). Lithgow and Essiedu’s casting choices ruffled a few feathers when first revealed, with die-hard fans airing classic internet outrage.

Meanwhile, the first teasers for the show have left the fandom split. Some don’t fancy the colour palette (a bit grey for their tastes), others gripe about creative tweaks, and there's the perennial grumbling about whether a reboot was ever needed. You do rather have to laugh — we all know Potterheads aren’t exactly shy with their opinions. That said, we now have the view from the top at HBO itself: CEO Casey Bloys has seen every episode of the premiere run and gave his thoughts to Bloomberg during a recent chat.

Here’s what Bloys had to say about his early screening experience:

I have seen the entire season and it is great and I'm very, very happy. So, I feel really, really good about that Christmas Day. I think a lot of people will be watching around the globe.

He's clearly chuffed with how it's turned out, and is backing the team even as the online sniping continues. For HBO, it’s a monster gamble: the books still have one of the most relentless fanbases on planet Earth, and the expectations are not exactly modest.

Eight episodes, Christmas launch

Bizarrely, all this is coming much faster than expected—the whole season wraps with a Christmas Day release, at least in Bloys' own estimation. The streamer has already kicked off filming for Season 2, so there’s little risk of endless waits (or at least nothing as glacial as some of their prestige back-catalogue).

Season 1 will land on Christmas Day, giving HBO a flagship event for the holiday telly slot.

This first season will follow Harry Potter and the Philosopher's Stone over eight episodes, and yes, just to clear it up, the idea is a single book per season. They’re not doing it annually, though – Bloys told The Times you can’t expect the show to drop every year, as 'the show is too big and too massive.' There’s a ticking clock, too, since the child actors need to look vaguely the right age for their on-page equivalents — not a problem the old films ever really solved, but perhaps telly can do better, if only just.

If you’re wondering how the cast are preparing for all this attention and scrutiny, Bloys has been frank about the realities: they’ve had blunt chats with the young leads about social media, fan reaction, and the unfortunate need for extra security that comes with so much IP baggage. Veteran or new, everybody’s getting the HBO crash course in handling a fandom ready to pounce at the first whiff of trouble.
