Independent horror films often promise realism, but few productions push that idea quite as far as Bonekeeper. Shown at Glasgow Film Festival 2026, written and directed by Howard J. Ford, the creature feature plunges audiences deep underground into a claustrophobic world of caves, ancient secrets, and a deadly creature lurking in the darkness.

Filming in Real Caves

Bonekeeper was shot largely in real underground cave systems. No studio sets, no controlled lighting, no warmth between takes. The result is something increasingly rare in horror: environments that feel genuinely threatening because they genuinely were.

Sarah T. Cohen, who stars in the film, described conditions that no set decorator could replicate. “It smelt really bad and it was really dark. If you didn’t have the torches, it was pitch black. And there were literal real dead animal bones down there that ended up in the film.”

Committed to the Bone

The cast felt it. Sophia Eleni recalled long hours underground, the air thick and strange. “We all got really ill. We thought there was something called cave-lung.” She says it with the laugh of someone who survived it and would probably do it again.

Danny Rahim found that the physical reality sharpened the performances in ways rehearsal never could. Cast members instinctively checked on each other between takes “you alright? have you got that step?” exactly as real people would if the danger were genuine. “It added to the realism of the film,” he said. “Because it was real.”

Even a close call with a precarious boulder Ford describes it, with characteristic understatement, as “a death boulder, held by a pebble”, only deepened the cast’s commitment to the world they were building together.

A Monster Worth Watching

For Ford, the hope is that audiences embrace both the creature and the effort that went into making the film. “There are a lot of rubbish creatures around,” he admitted. “I didn’t want to do that. If you’re going to do a creature film, you need a really good monster.”

If early reactions are anything to go by, Bonekeeper might just deliver exactly that: a throwback creature feature with genuine underground danger and a passion for practical filmmaking.

Bonekeeper hits UK streaming on April 6th, with international release to follow.

It’s a film made by people who went somewhere most productions wouldn’t, endured what most crews wouldn’t, and came back with something that proves passion still hit harder than any studio budget ever could. That’s a rarer thing than it sounds.
