Grimmfest Is Running, ‘Clayface’ Is Coming for Halloween: Horror’s Best Year at the Box Office Is Bleeding Into Everything Else

Nobody expected Obsession to be the story. A micro-budget haunted-house film with no stars anyone outside the genre could name, and by late August it had crossed half a billion dollars worldwide, the first original film of the 2020s to do it. That alone would make 2026 a strange year for horror. It was not even close to the only headline.

Scream 7 made it official too: with no Jenna Ortega and plenty of doubt going in, it finished its run as the highest-grossing installment in the franchise’s history, over $207 million worldwide, beating out both the 1996 original and Scream 2 without adjusting for inflation. Resident Evil opened to $60.2 million and a 96% Tomatometer score, the biggest opening weekend an R-rated video game adaptation has ever had, in a genre where Silent Hill and Doom barely registered. Evil Dead Burn arrived in July from Sebastien Vanicek carrying some of the strongest buzz of the summer. And now Clayface, Warner Bros’ R-rated DC horror film, lands in cinemas from October 21, positioned as the big theatrical swing of the Halloween season.

Put those next to each other and the pattern is hard to miss: horror has not had a year like this at the box office in a generation, and it is not staying inside its own lane. It is already spilling into gaming, into comics, into the kind of digital entertainment that shares a visual language with every film on that list without being a film at all.

That spillover is the part worth paying attention to here, not the box office numbers themselves. Resident Evil‘s success pulled in an audience that was never purely cinema-literate to begin with, the overlap between horror fandom and gaming fandom that the franchise has traded on since the first game shipped in 1996. Clayface does the same thing from the other direction: a villain who has existed in DC comics for over eighty years, now headlining his own theatrical horror film in the same month Devolution readers are deep into Grimmfest coverage and already arguing about where Evil Dead Burn ranks in the franchise.

Online entertainment has picked up the same seasonal signal, for exactly the reason you’d expect: October is when horror sells, in whatever form it takes. UKGC-licensed casino platforms lean hard into horror-themed slot catalogues this time of year, titles like Halloween Jack, Blood Suckers 2 and The Wolf’s Bane carrying the same visual grammar as the films dominating cinemas right now, down to the typography. It is a genuinely seasonal category, the same way Christmas slots show up every December, and it runs in parallel with the theatrical calendar rather than competing with it.

For anyone curious where that leaves the licensed platforms themselves, the UK’s newest online casino sites is a decent place to start: a running comparison of which UKGC-licensed operators carry the stronger horror-themed slot libraries this month, what RTP actually means in practice when a game like Halloween Jack sits at 96.28% against something far leaner, and where the licensing checks that matter sit before a player deposits anything at all.

RTP is not a marketing number worth skipping over either; it is the single most useful figure on a slot’s info page, and the discipline of checking it mirrors something horror fans already do instinctively with box office claims. Resident Evil’s domestic run has now passed $125 million, a number that only means anything once you know it against the $75 million budget and the opening weekend that drove it. A slot’s RTP works the same way: the headline figure is only useful next to what it is being measured against.

We covered the other side of this month’s horror calendar in 5 Films You Can’t Miss at Grimmfest 2026, and the festival’s lineup this year makes the same point the box office numbers do: there is more genuinely good horror competing for attention in October 2026 than there has been in years, across every format it can reach.

Halloween is still three weeks out and the genre has already had its best twelve months since the slasher boom of the late 1990s. Clayface is the last big theatrical swing before the month ends, and if Obsession and Resident Evil are any guide, the audience showing up for it will not stop at the cinema doors. It rarely does anymore.
