Mentawai Documentary Film Project
1. LOGLINE
Deep in the rainforests of Siberut Island in Indonesia, one of the world’s most intact animistic cultures continues to live. Through the lives of a Mentawai family spanning three generations, the film explores whether ancient knowledge of the forest and spirit world can continue in a rapidly changing society.
2. Project Overview
Deep in the rainforests of Siberut Island in Indonesia, one of the world’s oldest Indigenous cultures still survives.
The Mentawai people have lived for thousands of years in a forest‑based society shaped by ritual, shamanism, and an animistic worldview in which humans, animals, plants, and objects all possess souls. Their traditional belief system, Arat Sabulungan, understands the forest as a living spiritual world where balance must constantly be maintained.
At the center of this society are the kerei (shamans) — healers, ritual leaders, and mediators between the human and spiritual worlds.
But this world is changing rapidly.
Government resettlement programs, missionary influence, education, and globalization have profoundly altered Mentawai life over the past century. Today, only a small number of clans continue to live traditionally in the forest.
Mentawai — A Living Spiritual World is a long‑form documentary that captures the daily life, rituals, knowledge, and transformation of one of the world’s last living rainforest cultures — told from within the community itself.
This film is not about a disappearing culture, but about a society deciding what knowledge it will carry forward into the future.
3. SHORT SYNOPSIS
On Siberut Island in Indonesia, the Mentawai people have lived for thousands of years in a rainforest world where humans, animals, plants, and objects all possess souls. Their spiritual system, Arat Sabulungan, governs daily life through rituals, taboos, and the guidance of shamans known as kerei.
But this world is changing.
Missionary influence, government resettlement programs, education, and globalization have reshaped Mentawai society within a single generation. Only a small number of clans continue to live traditionally in the forest.
Mentawai — A Living Spiritual World follows several families as they navigate the delicate balance between cultural continuity and modern change. Through ceremonies, forest life, and intimate conversations across generations, the film captures a society deciding what parts of its ancient knowledge will survive into the future.
4. Why This Film Matters
Despite global fascination with Indigenous cultures and rainforest societies, there is currently no comprehensive modern documentary film portraying Mentawai life from within the community itself.
The most widely referenced film about the Mentawai — the BBC ethnographic documentary The Sakuddei (1974) — is now more than half a century old. While historically important, it reflects an external anthropological perspective rather than a long-term relationship with the people whose lives it portrays.
Most existing representations of the Mentawai are fragmented, external, or tourism-driven, offering little insight into lived experience within the community today.
This absence is particularly striking given the global cultural and ecological significance of the Mentawai.
The Mentawai are among Indonesia’s oldest Indigenous cultures, with roots stretching back thousands of years. Their cosmology — Arat Sabulungan — represents one of the world’s most intact animistic belief systems, structured around the idea that humans, animals, plants, and even objects possess spiritual essence.
Equally remarkable is the Mentawai’s ecological knowledge of the rainforest environment. Their understanding of plants, forest ecosystems, and the balance between human activity and the natural world reflects generations of accumulated knowledge that is increasingly relevant to contemporary conversations about sustainability and biodiversity.
Yet today this knowledge faces a profound transition.
Over the past century, government resettlement programs, missionary influence, formal education, and economic change have transformed Mentawai society. Many families have moved away from traditional forest settlements, and fewer young people are choosing to follow the demanding path of becoming a kerei, the Mentawai shamans who carry much of the community’s spiritual knowledge.
The result is a moment of cultural transition rarely captured on film: a society whose traditions are still alive, yet whose future is being quietly negotiated by a new generation.
It is precisely at such moments — between continuity and transformation — that documentary storytelling becomes most meaningful.
This film offers a rare opportunity to document Mentawai life from within the community itself, made possible by a relationship with the family at the center of the story that spans more than three decades.
5. Director's Statement
For more than thirty years, the Mentawai people have been part of my life.
I first traveled to Siberut Island in 1990 and was welcomed into a Mentawai family living in a traditional uma longhouse along a forest river. Over time, the late shaman Aman Patre and his wife, now called Teteu, adopted me into their family.
Since then, I have returned regularly — living with them, learning their language, and sharing daily life. Through these relationships, I came to understand the values that shape Mentawai society: balance with the forest, responsibility toward the spirit world, and the deep bonds of community.
This long-term relationship allows the film to be made from within the community, rather than observed from the outside.
Over the decades, I have witnessed Mentawai life change.
Children who once learned forest knowledge daily now attend schools in distant villages. Mobile phones appear in places that were once completely isolated. Some families have moved away from the forest, while others continue to maintain traditional life in their ancestral territories.
Yet the core of Mentawai culture remains remarkably strong.
At the heart of this world are the kerei, the Mentawai shamans — healers and mediators between humans and the spirit world. Their knowledge has evolved over thousands of years, yet today it stands at a fragile threshold.
Becoming a kerei requires years of training, discipline, and responsibility. Increasingly, fewer young people feel able to follow that demanding path.
This moment — when a culture is still fully alive yet its future is being renegotiated — is precisely when documentation becomes most meaningful.
The story of this film unfolds within the family that welcomed me decades ago.
Teteu, now in her late seventies, raised six children after the death of her husband, the respected shaman Aman Patre. Two of her sons, Aman Manja and Aman Sasali, have become shamans themselves. Aman Sasali now raises his own children in the same forest landscape where their grandparents once lived.
Among them is his son Tona, a teenager who stands between two worlds: the expectations of tradition and the possibilities of modern life.
Through their lives, the film follows a simple but profound question:
Who will carry this knowledge forward?
This film is not intended as an ethnographic study of a remote culture, nor as a nostalgic portrait of a disappearing world.
Instead, it is a story about continuity, responsibility, and the choices faced by younger generations in a rapidly changing society.
My aim is to create a documentary that allows viewers to experience Mentawai life as it is lived — through the rhythms of the forest, the sounds of ritual song and dance, the preparation of food, the sharing of knowledge between generations, and the quiet moments that shape the future.
Because of the trust built over decades, this story can be told from within the community itself.
Ultimately, this documentary is both a portrait and a record — a portrait of a society that continues to live in profound relationship with its environment and spiritual traditions, and a record for future generations of how this world was lived at a moment when its future was being quietly negotiated.
6. Story Concept
The film follows a Mentawai family living along a remote river valley on Siberut Island in Indonesia, the cultural heartland of the Mentawai people.
Through their lives we experience the rhythms of a Mentawai world shaped by the forest and the spiritual system known as Arat Sabulungan.
Daily life unfolds through:
- the building and life of the uma longhouse
- hunting and forest subsistence
- sago harvesting and fishing
- the preparation of medicinal plants
- shamanic healing rituals and ceremonial life
Within this world, the boundaries between the physical and spiritual realms are fluid. Rituals guide the balance between humans, animals, and the unseen forces believed to inhabit the forest.
At the same time, new realities enter this environment.
Children travel to schools in government villages. Mobile phones appear in remote settlements. Younger generations begin to question whether they will follow the demanding path of becoming a kerei, the Mentawai shamans who maintain spiritual balance within the community.
Families increasingly move between two worlds — the forest settlements of their ancestors and the growing influence of modern Indonesian society.
Through the lives of three generations within one family, the film explores a fundamental question:
What happens when a culture built on balance with the forest confronts a rapidly changing world?
The film unfolds through a series of observational chapters that follow daily life, ritual practice, and the growing question of who will carry Mentawai knowledge into the future.

7. Story & Narrative Structure
PROLOGUE — THE SONG
Night inside a Mentawai uma longhouse.
A shaman sits cross-legged in the dim firelight and begins to sing a sacred urai song.
There is no explanation.
Only:
- the voice
- the forest night outside
- the flicker of firelight on wooden beams
- people sitting quietly along the walls
The song moves slowly through the house.
The camera lingers on faces illuminated by firelight.
Children watch silently.
The song continues.
Voice-over:
“For the Mentawai, the world is alive with souls.“
Title appears.
MENTAWAI — A LIVING SPIRITUAL WORLD
ACT I — THE FOREST WORLD
Morning arrives in the forest.
Mist drifts above the river.
A canoe moves silently through the water.
Inside the uma, daily life begins.
Women prepare food near the hearth.
Children move between the pillars of the house.
Pigs and chickens wander beneath the raised floor.
We enter the rhythm of Mentawai life through Aman Sasali and his family.
We see:
- sago harvesting in the forest
- fishing along the river
- walking narrow forest trails
- children playing near the house
- cooking and preparing food inside the uma
Gradually we meet the central characters.
Teteu, the matriarch who raised her family after the death of her husband, the shaman Aman Patre.
Aman Manja, one of her sons and a respected shaman.
Aman Sasali, her younger son and the film’s central character.
And Tona, Aman Sasali’s teenage son.
Through these moments the forest is established not as wilderness, but as home.
The audience begins to understand the rhythm of life within this world.
ACT II — THE SPIRIT WORLD
A deeper layer of Mentawai life slowly emerges.
Ritual objects are prepared.
Leaves are gathered and arranged.
Sacred ornaments are attached to the bodies of shamans.
As night falls, ceremonies begin.
Inside the uma:
- drums echo through the house
- shamans dance across the wooden floor
- bells shake with every movement
- chants fill the room
During rituals, shamans enter trance and communicate with the spirit world.
Through these ceremonies we begin to understand the role of the kerei, the Mentawai shamans.
They are healers.
Mediators between humans and spirits.
Guardians of balance between worlds.
Aman Manja speaks quietly about the relationship between humans, nature, and the unseen world.
Mentawai spirituality is revealed not as symbolic belief, but as a system that shapes daily life.
ACT III — THE UMA
The camera slows.
The film lingers inside the uma.
This communal longhouse is more than a place to live.
It is where family life, ritual life, and memory come together.
We observe:
- communal meals around the hearth
- storytelling late at night
- preparation of ritual objects
- quiet moments of rest
- children learning through observation
Knowledge passes between generations through daily life rather than formal instruction.
In a quiet moment late in the afternoon, children sit on the wooden floor while Teteu watches them from near the hearth. Light enters softly through the open walls of the house. As the children play around her, she reflects on the time when her husband, the shaman Aman Patre, was still alive and ceremonies filled the house with song and dance.
For the children it is simply a story.
For Teteu it is a memory.
The house holds traces of countless moments — ceremonies, births, deaths, and generations that lived here before.
The uma becomes the emotional center of the film — a place where memory is carried forward and continuity is quietly maintained.
ACT IV — CHANGE
Gradually, tension enters the story.
The younger generation faces new possibilities.
Education.
Village life.
Modern technology.
We see signs of change:
- school uniforms hanging inside the house
- conversations about life outside the forest
- young people moving between village and forest
The focus shifts to Tona, Aman Sasali’s teenage son.
Tona recently left school and now stands between two worlds.
Will he remain in the forest?
Or choose a different life?
His father, Aman Sasali, reflects on the responsibility of becoming a shaman.
Aman Manja speaks about knowledge that may disappear if fewer young people follow this path.
The film’s central question emerges:
Who will carry the knowledge forward?
ACT V — THE FUTURE
A major ceremony unfolds.
People gather from nearby settlements.
Inside the uma the atmosphere becomes intense.
Drums begin.
Shamans prepare ritual leaves.
Offerings are arranged.
As night falls, the ceremony begins.
Shamans dance across the wooden floor.
Their stamping echoes through the house.
The entire community participates.
Children sit along the walls watching quietly.
Among them stands Tona, observing the ritual.
For the first time the audience sees the ceremony not only as spectacle, but as a living tradition being witnessed by the next generation.
The knowledge is still alive.
But its future remains uncertain.
EPILOGUE
Night inside the uma.
The drums begin again.
Shamans step onto the dance floor.
The stamping rhythm echoes through the house.
Firelight flickers across tattooed skin.
Along the walls, children sit quietly watching.
Among them stands Tona.
Feet strike the wooden floor in steady rhythm.
The sound fills the house.
But now the viewer understands what they are witnessing:
a world where
the forest
the spirits
the family
and the living tradition
remain bound together.
8. Main Characters
Teteu — The Matriarch: Represents memory and resilience.
Bajak — The Elder Shaman: Keeper of ancestral knowledge.
Aman Manja — Senior Ritual Authority: Represents the weight of tradition and ritual expertise.
Aman Sasali — Central Character: A father and active shaman bridging generations.
Tona — The Young Generation: Represents uncertainty about the future and the question of cultural continuation.
9. VISUAL STYLE & CINEMATIC APPROACH
The film will follow a cinematic observational documentary approach that allows Mentawai life to unfold naturally.
Key elements include:
- natural light cinematography
- immersive forest soundscapes
- long observational takes
- minimal narration
Influences include Honeyland and The Salt of the Earth. The camera functions as a quiet observer within the community.
The camera functions as a quiet observer within the community. The goal is to create a sensory experience of place, rather than an explanatory ethnographic film.
10. ACCESS & ETHICAL COLLABORATION
Because the filmmaker has maintained close relationships with the Mentawai family featured in the film for more than three decades, the project is based on long-term trust and collaboration with the community. The film will be made with the ongoing consent and participation of the family and clan whose lives are portrayed, ensuring that their perspectives remain central to the storytelling process.
11. Production Plan
Development: script development, partnerships, community collaboration.
Production: filming across multiple visits over 12–18 months to capture seasonal and ritual cycles.
Post‑production: editing, sound design, color grading, subtitling.
Distribution: targeting international documentary festivals including IDFA, Sundance, HotDocs, and Sheffield DocFest.
12. Impact
The film aims to become a cinematic record of Mentawai life in the early twenty-first century.
Beyond festival audiences, the film can contribute to cultural preservation, educational use, Indigenous knowledge documentation, and broader awareness of the relationship between traditional societies and their natural environments.
At a time when Indigenous ecological knowledge is increasingly recognized as essential to understanding sustainable relationships with nature, the Mentawai perspective offers insights that extend far beyond the islands where this culture developed.
Most importantly, the film will remain a record for the Mentawai themselves — for future generations who may one day wish to understand how their ancestors lived.
13. Closing Statement
The Mentawai world is not yet gone.
It is still alive — in the forests, in the uma, in the rituals and knowledge carried by elders.
But the window to document it meaningfully is closing.
This film seeks to capture that world while it is still being lived.
