Investigation into the Invisible World

Lore & Background

The film features interviews with several Icelanders who recount playing with elves as children. Mediums sometimes contact the Icelandic Road Administration when a planned road crosses a known elf site, and the agency takes measures to avoid causing problems for the elves. Seismologist Ragnar Stefánsson argues that the elf phenomenon can be understood as a way to cope with Iceland's geology and volcanic activity. Neopagan leader Jörmundur Ingi Hansen explains it from a pagan cosmological viewpoint, noting that the term huldufólk—hidden people—emerged as a euphemism because the word 'elves' has a stronger religious connotation. Iceland's former president Vigdís Finnbogadóttir says she thinks the belief in elves and ghosts is strong in Iceland because Catholicism never was particularly strong.

Several people claim to have seen a monstrous sea serpent off the Icelandic coast, though these sightings are conventionally explained as hallucinations. Film director Friðrik Þór Friðriksson and others discuss personal sightings of UFOs and encounters with what they believe were extraterrestrial beings. Icelanders tell stories about ghost encounters; the manager of Hótel Borg in Reykjavík contacts a medium after unusual activities and is told there are many ghosts at the hotel. Mediums, a priest, scientists, clairvoyants, and healers present their experiences and theories about paranormal phenomena. Participants express hope that their practices will be unified with science and that more people will have access to their abilities.

Reader's Guide

Investigation into the Invisible World is significant as a documentary that catalogs a wide range of paranormal beliefs held by Icelanders, from elves and hidden people to sea serpents, UFOs, ghosts, and angels. It presents these beliefs without judgment, allowing interviewees—including scientists, a former president, a neopagan leader, and ordinary citizens—to speak for themselves. The film's reception was mixed: Le Monde's Jacques Mandelbaum considered it a missed opportunity for not exploring cinema's possibilities beyond putting interviews to music, while Libération's Bruno Icher praised its appreciation for Iceland's paganistic charm and called it a 'throbbing and delirious lullaby where discerning the true from the false does not have the slightest importance.' Variety's Eddie Cockrell described it as 'hugely entertaining' and a 'nature documentary as otherworldly thriller,' noting its technical tricks. The film was shown at international festivals including Karlovy Vary, Toronto, and Sundance between 2002 and 2004. Its legacy lies in documenting a cultural phenomenon that blends folklore, geology, and spirituality in modern Iceland.

• Several Icelanders interviewed in the film say they used to play with elves as children.
• Iceland's former president Vigdís Finnbogadóttir says the belief in elves and ghosts is strong because Catholicism never was particularly strong in Iceland.

The Icelandic Supernatural Landscape

The documentary centers on the rich tapestry of paranormal belief woven into Icelandic daily life. From childhood memories of playing with elves to the practical measure of the Icelandic Road Administration rerouting projects to avoid known elf sites, the film presents a culture where the supernatural is not merely folklore but an active part of social infrastructure. Beyond the huldufólk, the film ventures into sightings of a monstrous sea serpent along the coast, personal UFO encounters, and ghost stories that haunt Reykjavík's Hótel Borg. The conventional explanation for the sea serpent is dismissed as hallucination, yet the film lets these accounts stand alongside scientific and spiritual interpretations without forcing resolution. This breadth—from tiny hidden folk to cosmic visitors—gives the documentary a sweeping scope that treats every layer of the invisible world with equal curiosity.

A Chorus of Voices

Roux assembles a remarkably diverse panel of speakers, each offering a different lens on the same phenomena. Seismologist Ragnar Stefánsson proposes that the elf phenomenon functions as a psychological coping mechanism for Iceland's volatile geology and volcanic activity. Neopagan leader Jörmundur Ingi Hansen reframes the discussion through a pagan cosmological lens, noting that the term huldufólk—hidden people—served as a euphemism because the word for elves carried heavier religious weight. Former president Vigdís Finnbogadóttir attributes the persistence of such beliefs to the historically weak grip of Catholicism on Icelandic society. Film director Friðrik Þór Friðriksson shares personal UFO encounters, while a hotel manager, mediums, a priest, scientists, clairvoyants, and healers each contribute their own theories and practices. The result is a polyphonic portrait where no single authority dominates the conversation.

Festival Circuits and Critical Response

Premiering in French cinemas on 30 September 2002, the film went on to travel through a notable run of international festivals between 2002 and 2004, including the 38th Karlovy Vary International Film Festival, the 2003 Toronto International Film Festival, and the 2004 Sundance Film Festival. Critical responses were divided. Jacques Mandelbaum of Le Monde felt the film squandered its subject by pairing interviews with music rather than pushing the boundaries of cinematic form. Bruno Icher of Libération, by contrast, praised the director's evident affection for Iceland's paganistic charm, describing the result as a "throbbing and delirious lullaby" in which distinguishing truth from fiction barely matters. Eddie Cockrell of Variety lauded the film's "breathtaking bag of technical tricks," calling it hugely entertaining and likening it to a nature documentary crossed with an otherworldly thriller.

Between Faith and Inquiry

The film's structural premise is one of open-ended investigation rather than definitive proof. Roux positions himself as a curious observer, letting participants articulate their beliefs without imposing a verdict. Scientists and clairvoyants are given parallel platforms to lay out competing theories about paranormal experiences, while healers describe their practices and mediums recount their encounters. The neopagan and Catholic perspectives coexist without one being privileged over the other. Notably, the film closes on a forward-looking note: participants express hope that their spiritual practices will eventually be unified with science and that broader access to these abilities will become possible. This aspirational ending, combined with the film's refusal to mock or fully endorse any single worldview, positions the documentary as a bridge between rational inquiry and lived faith, inviting the audience to sit comfortably in the ambiguity.
