It: Welcome to Derry Surprise-Releases a 30-Minute Halloween Special Set Centuries Before Pennywise

HBO Max did not announce this one. Overnight on 31 October 2026, the service put a 30-minute episode of It: Welcome to Derry online under the title "A Story of Derry", with an ASL variant and a listing of its own, separate from the main series. Variety and Deadline both reported the drop on Halloween morning.

The obvious reading is that this is the start of season 2. It is not. "A Story of Derry" is a standalone side story, dropped for the holiday, and season 2 is a different production in a different decade. Anyone who queues the special expecting the next chapter of the 1962 story will spend 30 minutes waiting for characters who are not in it.

What they will get instead is the oldest thing the show has attempted: a story set hundreds of years before the events of season 1, in a forest that was already hungry.

What actually dropped, and what it is not

The details are modest and easy to list. Thirty minutes, directed by Tazbah Chavez, written by Cherie Dimaline and Jasmyne Flournoy according to Gizmodo. HBO Max lists it as its own entry, with a separate ASL version, rather than slotting it into the season 1 run.

That framing matters more than it sounds. A surprise drop can mean a bonus instalment that continues the current arc. A separate listing says the opposite: this is a short film in the show's universe, and it does not owe the main plot anything.

Season 1 premiered on HBO Max on 26 October 2025, so the special lands a little over a year later, in the gap between one season and the next. That gap is the point. A show with a finished season behind it and an unfinished one ahead has little to offer in October except a reminder that it exists.

The timing is the whole reason it exists in this shape. Halloween is the natural window for a horror series, and the show is between seasons, with the next one not expected until late 2027 or 2028. A 30-minute side story fills that gap without committing the production to a premiere date it cannot yet hit. There is no published ratings motive here, and none should be invented. It arrived as a holiday extra, sized to be watched in one sitting.

Three children, and a forest older than the town

The premise is deliberately small. Three children enter the Western Wood and meet a terrifying ancient spirit there. That is the entire engine, and it is enough for half an hour.

The setting does a lot of work that dialogue would otherwise have to. Season 1 introduced the tribe and the ritual that bound the entity to the forest as history behind the 1962 story. A story set centuries earlier can put that material on screen instead of in an explanation, with a forest and a handful of people who have not yet agreed on what the place is.

The first season kept that history at a distance from its 1962 characters. The casting follows that shift: Kimberly Guerrero returns as a young Rose, Morningstar Angeline and Kiawentiio appear as past warriors Sesqui and Necani, and Zahn McClarnon joins the episode. Putting named faces and a language on it is a real change of method.

The episode expands that material rather than detouring from it. A side story about the ritual can also answer a question the main timeline cannot: what the binding actually cost the people who performed it.

The one review, and what it says

Only one written, scored review was available at the time of writing. Tyler Nichols at JoBlo published on 1 November 2026 and scored the episode 7/10, which the site labels "GOOD". That is a single critic's verdict, and it should be read as one.

The praise is specific. Nichols responds to what he calls a Prey-like aesthetic, the choice to open in a Native language before switching to English, and the arrival of Maturin the Turtle, which he describes as the character's first substantial on-screen appearance, rendered as a cosmic figure. He also flags that Pennywise turns up as a moose, which is the kind of image a 30-minute runtime can afford and a full season probably could not.

The criticisms are equally specific, and they follow from the format. Thirty minutes leaves little room to build dread, so the monster arrives early and stays visible. Nichols notes that the runtime forces the creature on screen quickly, and that the characters make stupid decisions along the way. Those are the standard costs of a short horror story, and they land harder when the audience has already spent a season with more patient storytelling.

His summary is that the episode tells readers of Stephen King's novel little they do not already know, but adds depth to the show's mythology and works as a one-off. That is a fair description of what a side story can do. It is not trying to surprise the book audience. It is trying to make the show's invented history feel older than the show.

Maturin, and why the cameo is the story

The Maturin appearance is the part fans will argue about, and it needs a caveat. According to Nichols, the turtle shows up inside a drug-induced trip. That framing matters, because it means the episode is not making a clean claim about what is real in the show's world. It is showing the characters something, and letting the audience decide how much of it to trust.

Within that limit, the choice is interesting. Maturin is rendered as a cosmic figure, not a mascot, and the review treats the scale as the point. For a series built around a clown, a turtle the size of a sky is a different register of fear. It also gives the show somewhere to go that does not require Bill Skarsgård to put the makeup on again.

The risk is that a cosmic cameo in a 30-minute episode reads as fan service rather than story. The defence is context: this is a story about the ritual that bound the entity to the forest, so a creature older than the entity belongs in the frame. Whether the execution earns that is exactly the thing a single review cannot settle.

There is also a practical reading. A show about a shapeshifting entity has an obvious production problem: every new form is a new build, and every Pennywise scene needs Skarsgård. A cosmology with more than one ancient thing in it gives the writers somewhere to put the horror that is not a clown. The special is a 30-minute test of whether that idea holds up.

Caveats: one review and no aggregate

This is the part that usually gets skipped. As of writing, no Rotten Tomatoes or Metacritic aggregate existed for "A Story of Derry". The JoBlo 7/10 is one critic's score, published a day after the drop, and it is not a consensus.

That is normal for a surprise release. Aggregates usually need a screening window, and a Halloween drop with no advance press means reviews arrive after the audience does. It also means readers should treat any number they see attached to the special with care, including the one in this piece. A 7/10 from one outlet is a reasonable signal about craft. It is not evidence about how the episode will sit with the wider audience, and there is no audience score to compare it against either.

Viewers who liked season 1's lore episodes more than its jump scares are the audience for this. Viewers who wanted the clown get a moose and a turtle instead.

Season 2 is a different animal

The thing to keep separate from the special is the actual next season. HBO Max renewed the show in August 2026. Season 2 is set in 1935, during the Great Depression, and centres on the Bradley Gang massacre, an interlude from King's novel.

Andy Muschietti has described the aesthetic as a break from the 1962 season: a town of poor, tired, jobless residents and orphaned or runaway kids. That is a period piece with a different palette, a different cast of children, and a different relationship to the town's violence.

On the surface, Derry is a graveyard almost. It's a carcass of something because people are depleted, poor, tired, jobless, homeless.

The schedule is the reason the special exists at all. Season 2 is expected in late 2027 or 2028, and scripts were about halfway written when Muschietti and the showrunner spoke earlier in 2026. A 30-minute episode does not shorten that wait. It does give the show something to be discussed for in the meantime, and it tests whether the mythology can carry a story without the 1962 cast.

What to watch

The useful question is not whether the special is good. It is whether the show can keep making these. A standalone episode that expands the ritual gives the series a second mode, one that does not depend on Pennywise's schedule or Skarsgård's availability, and that mode does not need the 1962 cast to return.

If HBO Max orders more of them, the model gets a second run. If it does not, "A Story of Derry" stays a Halloween curiosity: a well-cast, sharply limited experiment that arrived without warning and left the main timeline exactly where it was. Either way, season 2 remains the real test, and it is still a long way off.
