Investigation into the Invisible World

A documentary exploring Iceland's belief in elves, ghosts, and the paranormal.

Last updated 12 October 2026

Investigation into the Invisible World is a 2002 French documentary by Jean-Michel Roux. It examines how paranormal beliefs are held by people in Iceland. Many Icelanders interviewed recall playing with elves in childhood. When road construction risks disturbing known elf sites, mediums sometimes contact the Icelandic Road Administration, which then takes steps to avoid troubling the elves.

Seismologist Ragnar Stefánsson suggests the elf phenomenon helps people cope with Iceland’s geology and volcanic activity. Neopagan leader Jörmundur Ingi Hansen offers a pagan cosmological view, noting that the term huldufólk (hidden people) arose as a euphemism because “elves” carries a stronger religious meaning. Former president Vigdís Finnbogadóttir attributes the strong belief in elves and ghosts to the fact that Catholicism was never particularly powerful in Iceland.

Several people claim to have seen a monstrous sea serpent off the coast. These sightings are usually explained as hallucinations rather than spirits or unknown animals. Director Friðrik Þór Friðriksson and others describe personal UFO sightings and encounters they believe were with extraterrestrials. Icelanders share stories of ghost encounters.

The manager of a Reykjavík hotel, after unusual activity, consulted a medium and was told the hotel harbors many ghosts. Mediums and a priest discuss their experiences and ideas about angels. Scientists and clairvoyants present theories on paranormal experiences.

Healers describe their practices. Participants express hope that their abilities will one day be unified with science and become more widely accessible. The film premiered in French cinemas on 30 September 2002 and appeared at international festivals from 2002 to 2004, including the 38th Karlovy Vary International Film Festival, the 2003 Toronto International Film Festival, and the 2004 Sundance Film Festival. Le Monde’s Jacques Mandelbaum considered it a missed opportunity, arguing it fails to explore cinema’s possibilities beyond setting interviews to music.

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.
