We’re seeing a trend of Creepypasta adaptations coming back, and Siren Head is the next internet horror phenomenon to be adapted for the big screen.
Creepypasta-based movies have varied in quality over the years, whether it’s the terrible Slender Man or the critically acclaimed Backrooms, and it seems we’re about to get even more new horror movies based on these terrifying online tales.
When it comes to Siren Head, it already has a strong team behind it. Trevor Henderson’s original creation has been picked up by Warner Bros., with Weapons‘ Zach Cregger and Whalefall‘s Brian Duffield working on the script, according to reports from Deadline.
Siren Head has all the ingredients to be a successful horror movie, but it’s, of course, too early to say if it will ever reach the heights of Backrooms, which became the second highest-grossing horror movie of 2026 with box office takings of $331 million.
The question is, will a Siren Head movie work as a feature length? At the moment, I’m not entirely convinced.
Siren Head’s short film was good, but I’m not sure a feature length movie is necessary
Sometimes, less is more. That’s how I feel about Siren Head, as the creepy cryptid is well suited to short-form entertainment like YouTube videos and quick horror games. Will it have the same impact with a longer runtime?
Creepypasta stories are often quite simple, and Siren Head is no exception. The creature is known for camouflaging with its surroundings before attacking anyone in its vicinity, with the Siren Head wiki page explaining it is responsible for “a large number of disappearances across suburbia and rural environments”.
Scary as it is, I’m worried there’s not enough substance to make this work, and we may get bored with Siren Head’s modus operandi of chasing and killing anyone in its path, seemingly for no reason, before doing it all over again.
Backrooms, on the other hand, is more of a slow burn and requires deep exploration to uncover the true horror, which is why I think it has done exceptionally well theatrically. There are lots of areas, lore, and monsters to explore, and the Backrooms fandom is full of fan-created levels featuring new threats and ideas.
Like the Backrooms, the storytelling possibilities seem infinite. It is a vast, terrifying space with weird set design and that signature dark ambient sound design to keep us on edge. Any character can set foot in it, often no-clipping out of reality unexpectedly. It’s ripe for multiple adaptations and interpretations, whereas Siren Head may not live up to that.
But, as I said, there is a strong team behind it. We may well be headed into a new era of very effective Creepypasta adaptations, and I’m excited if that’s true.
I’ll be following Siren Head closely, and I hope it’ll be a thrilling feature-length adaptation after all.
