Is a Siren Head movie happening?
UPDATE: A Siren Head movie has now been confirmed by the Hollywood Reporter to be in the works at Warner Bros. Pictures, with Zach Cregger (Weapons) and Brian Duffield (Whalefall) teaming up on the script.
Monsters that have long been haunting the internet are finding their way to the big screen.
2026 has already been a huge year for the world of creepypasta (internet urban legends) intersecting with Hollywood. Backrooms, Kane Parsons' feature length adaptation of his own series of YouTube shorts, has brought in $300 million at the global box office in four weeks. The Third Parent, an upcoming horror movie based on Elias Witherow's Tommy Taffy short story series that went viral on Reddit's r/NoSleep sub, is due for release next January.

The question is, will another internet nightmare soon be joining their ranks? Could Siren Head, the towering monster created by artist Trevor Henderson, be the next creepypasta to get the movie treatment? Nothing is confirmed yet — but if you look closely, there are clues.
What is Siren Head?
In a nutshell, Siren Head is a monster the height of a telegraph pole that's capable of blending into its surroundings while it hunts human prey. It was created by Henderson back in 2018, after a follower called Cally sent him an image of a graveyard framed against a blue sky. At this point Henderson was quickly building his social media by drawing monsters that he'd splice into photos. He liked Cally's image, and tried to draw something that he thought would look scary standing among the tombstones. Just like that, Siren Head was born.
"I was just drawing a long, emaciated figure, and I just had the idea to put a siren for its head because a) that noise has always terrified me, and b) I've always been kind of obsessed with the idea of numbers stations," Henderson told Mashable back in 2022. "Numbers stations are these radio broadcasts that are constantly playing — and no-one can identify their origins or what they're supposed to accomplish — that are just weird snippets of music, and strange voices saying odd number combinations. There's a lot of theories that they're like old Russian spy channels that have been abandoned and are still counting out codes."
It's difficult to overstate just how popular Siren Head has become in the years since Henderson shared that first image. It was a slow burn initially, but when YouTuber Markiplier — who recently had his own feature film success with Iron Lung — started talking about the monster on his channel in early 2020, millions of people tuned in.
The thing is now all over the internet. Siren Head-inspired content has millions of views on TikTok and YouTube. There are multiple unofficial Siren Head games on Steam and merchandise on Amazon (much of which has been created without Henderson's knowledge or permission).
"The internet just kind of takes stuff," Henderson said. "And there's not a lot you can do, really, especially when a character blows up like Siren Head did. It kind of stops becoming yours, in some ways, and starts becoming everyone's."
Is a Siren Head movie in the works?
Speculation around a possible movie adaptation has been ramping up over the past week. There's been a couple of reasons for this. First, Henderson has started posting frequently about the creature again on Instagram.
By itself, this isn't that unusual. Although Henderson has created hundreds of monsters, Siren Head is a favorite that pops up now and then. But it's worth noting that the frequency of his posts has dialled up — there have been a handful over the last week alone, including some found footage-style Reels featuring the creature's trademark siren call.
What's even more intriguing, though, is who's been commenting on these posts.
Beneath the above image, which Henderson posted about a week ago, movie producer Scott Glassgold replied with several eyes emoji. Glassgold, who founded production company 12:01 Films, is a big name in the horror movie space, particularly when it comes to adaptations based on viral internet urban legends (he's previously been involved in a number of deals, including stories that originally started on Reddit).
Glassgold's comment didn't go unnoticed. A commenter asked him directly about the possibility of a Siren Head movie in response, to which he replied with three slightly cryptic siren emoji. Henderson himself then responded to Glassgold with a little megaphone. Mashable reached out to Glassgold to ask about the possibility of a film, and his response was just as cryptic. "I'm a huge fan of Trevor's and will be first in line to see anything he does," Glassgold said.
Henderson, when asked about the potential for a movie, also didn't give much away. “I'd be delighted," he told Mashable. "I think Siren Head has a lot of potential to be expanded into a film, but we’ll have to see. Either way, it makes me very happy that people still respond positively to the creature design in 2026."
So, what does it all mean? Well so far, there have been no official announcements and this is all speculative. But Glassgold's comments — plus the fact he's been sharing Henderson's recent Siren Head Reels — seem too deliberate to be chalked up to mere coincidence.
Here's hoping the creepypasta-to-movie pipeline gets a telegraph pole-sized extension in the near future.
