We still want the scrapped ‘Harry Potter’ spin-off — shame about the unbeatable snag

So, as Warner Bros. lines up its Harry Potter reboot for HBO, it turns out we almost got a different trip back to Hogwarts — and honestly, this one would have caused more panic in the fandom than a Dementor at a birthday party. The project? A Marauders prequel, digging into the messy, tragic, and occasionally hilarious backstory of the infamous troublemakers from the original series.

The Harry Potter reboot drops on HBO and HBO Max this Christmas, 25 December.

The spin-off we nearly had

According to reporting out of Knight Edge Media, Warner Bros. had a proper play at making a Marauders TV show. Writers were brought in, ideas tossed about, presumably with a bit of fan-casting in the air, before the whole thing was sent packing in favour of just rebooting Harry’s main story. Surprising? Probably not, considering how cautious studios are with anything remotely risky. Disappointing? For a lot of people, absolutely.

Let’s be real: the Marauders have always been the white whale of Potter spin-offs. Their wild Hogwarts years, complicated friendship with Snape, oh, and the little detail about being hunted by Voldemort – it’s the perfect cocktail for a binge-worthy series. You'd have James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew (yes, let's pretend for argument’s sake that Wormtail gets invited to the pub), plus Lily Evans, darting through a period that’s properly loaded with drama and unavoidable heartbreak. Even in the books, most of these lot barely get more than a few decent scenes. A spin-off could be a chance to finally give them room to breathe, especially Sirius and Lupin, whose arcs always felt rushed onscreen.

• Warner Bros. considered a Marauders series before opting for a main timeline reboot
• The Marauders’ era would cover Hogwarts hijinks, rise of Voldemort, and the original Order of the Phoenix
• The project was ultimately dropped over concerns about narrative stakes and surprise

But was it doomed from the start?

Here's where the headache comes in: if you're serious about a Marauders show, you already know exactly which way the wind’s blowing. Practically every big moment – the deaths, the betrayals, the final fates – have been mapped out right there in the books. Think about it: Prisoner of Azkaban spells out the night Lily and James are killed, and we’ve already watched (and re-watched) Sirius’ downfall and Pettigrew’s little hobby of backstabbing his friends. So while you could certainly go deep on their friendships and trauma, the fundamental problem is that 'prequel syndrome' – the audience basically knows where every storyline crashes and burns before a single frame starts rolling.

The best spin-offs twist your expectations. They may start with something familiar, but then tip it on its head, giving you a reason to rewatch the original with new eyes. But with the Marauders, any new show is boxed in – you can add new characters to the Hogwarts crowd, or double down on the Order of the Phoenix adventures, but none of it would have true suspense. The fate of the central gang is fixed, right down to the last rat, and when the real heartbreak lands – Lily and James, that betrayal – we already know it's coming. There are only so many secret rooms at Hogwarts that the books didn’t mention.

The reboot faces its own tension problems

Now, as for that shiny new HBO Harry Potter reboot, it’s a similar conundrum. Yes, the show is promising a fresh crack at the original books, with more screen time for the sort of scenes that had to be trimmed from the films. But in 2026, you’ll be hard-pressed to find anyone above the age of twelve who doesn’t already know where the big plot twists land. Unless the writers go completely off-piste — which would start a war online — you’re left with the same problem: pleasing the hardcore crowd while giving newer viewers reason to actually care about the outcome. The reboot’s real audience, then, is those rare souls who haven’t been through Harry’s story before. For the rest of us, it’s a nostalgia trip, not a journey into the unknown.
