Documentaries have a reputation for being “serious cinema” — educational, informative, maybe even a little stiff. But dig into the stranger corners of the genre, and you’ll find films that are anything but conventional. Some are hilariously absurd, others deeply unsettling, and a few blur the line between truth and surrealism so much you’ll wonder if you accidentally took the wrong streaming exit.
That’s the joy of documentaries: they’re not confined to tidy narratives. They follow obsessions, fixate on eccentric details, and sometimes turn the camera toward realities so bizarre they feel fictional. These are the films that make you laugh nervously, scratch your head, and text a friend: “You have to see this — I can’t explain it.”
Here’s our pick of 10 of the weirdest documentaries ever made — five of them streaming now on Guidedoc — guaranteed to challenge your sense of what non-fiction cinema can do.
Finders Keepers
Resurrect Dead: The Mystery of the Toynbee Tiles
Centipede Sun
Tickled
Holy Hell
It starts with a severed leg in a grill bought at a North Carolina auction. It spirals into a custody battle between the man who found it and the man it used to belong to. Equal parts tragic and hilarious, this film is proof that truth is stranger than trash TV.
Allan King’s groundbreaking 1969 film turned ten months inside a Toronto home into a raw portrait of love, conflict, and gender politics. A Cannes Directors’ Fortnight selection, it remains a visceral milestone in documentary history.
For decades, strange tiles bearing cryptic messages about resurrecting the dead appeared on streets across North and South America. Who put them there? Why? This lo-fi mystery documentary follows a group of obsessed amateur sleuths into the rabbit hole of urban paranoia.
Using raw footage from YouTubers, Dominic Gagnon assembles a chaotic constellation of voices that capture the spirit of our times: fake news, viral fears, and truths that spread faster than they can be verified. This documentary maps a digital landscape where meaning is stitched together only because we’re all perpetually online.
What do you get when you combine apocalyptic landscapes, hybrid creatures, and hypnotic sound design? A fever dream masquerading as a documentary. The Centipede Sun doesn’t explain itself — it crawls into your subconscious and refuses to leave.
In this artistic erotic documentary, Wim and Floor, a young couple, spend an afternoon together in a decaying Belgian home. Shot in real time, the film lingers on their slow, tender explorations, unfolding into a meditative portrait of love, desire, and intimacy.
Journalist David Farrier stumbles upon a seemingly harmless “competitive endurance tickling” video online. When he investigates, he’s met with threats, lawsuits, and a sprawling network of fetish exploitation. Equal parts dark comedy and horror, Tickled proves that kink and corruption make for truly bizarre viewing.
Winner of the Student Academy Award, this playful mockumentary follows a zoologist and a biochemist into an oilfield to study the elusive “oil gobblers.” Half scientific expedition, half absurd parody, the film turns industrial ruins into the unlikely habitat of creatures born from our own excess.
Coral reefs filmed like alien cities, creatures floating like dreams. This short transforms marine life into an uncanny, pulsating world. It’s science, yes, but science seen through the eyes of a poet on psychedelics.
Imagine filming your friends in a meditation group for two decades, only to realize you’ve actually joined a cult. That’s Holy Hell, a deeply unsettling inside look at the secretive Buddhafield cult — complete with sequined Speedos, guru worship, and trauma masked as enlightenment.
If bizarre stories are your thing, don’t miss our Guidedoc feature Truth, Stranger Than Fiction: The Ten Weirdest Documentaries That Will Flip Your Reality — a wild ride through films that prove life is far stranger than any screenplay.
So why highlight the weirdest of the weird? Because in 2025, when our feeds are drowning in AI-generated nonsense and recycled content, these documentaries remind us of the real power of cinema: to confuse, shock, and fascinate us with reality itself.
They also prove that “weird” isn’t just novelty — it’s perspective. Whether it’s coral reefs turned into cosmic cities or a courtroom battle over a severed leg, these films push us to see the ordinary as extraordinary, the familiar as alien. And that’s exactly what a documentary should do: stretch our understanding of the world until it snaps.
From cults in Speedos to cryptic tiles and tickling conspiracies, these ten films stretch documentary to its strangest edges. They are messy, unsettling, and often hilarious — proof that truth doesn’t need polish to captivate.
And five of them are streaming right now on Guidedoc. If you’re ready to dive into cinema’s oddest corners, Guidedoc is the place where the weird doesn’t just live — it thrives.
