Reviews and Festivals
"Extraordinary and necessary film. A poetic journey into the teeth of collapse that leaves us with one question: how will I comport myself during this time?"
— Dahr Jamail, author of The End of Ice: Bearing Witness and Finding Meaning in the path of Climate Disruption
"A triumph. With rare aesthetic taste, it delivers the facts about our accelerating climate chaos with an almost tender respect for those of us confronting the crisis. Unforgettable portraits of climate leaders in Bangladesh, France, and the US, help make our own choices clear. They leave me feeling inspired to lead a life that is relevant to this global movement."
— Joanna Macy, featured in A Wild Love for the World: Joanna Macy and the Work of Our Time
"A loving, beautifully crafted, deeply evocative film, if one can use those words to describe the poetic personal journey of Emmanuel Cappellin through his fear of inevitable global ecological collapse and chaos to his belief that only a vision of local, community resilience and a transition to new ways of living, creating, and organizing can save us. For those of us working on the edge of this collapse and hopefully this transition, once you know you can never unknow. You can only act."
— Peter Gleick, Scientist, Co-Founder of the Pacific Institute
"A beautiful, heart-breaking, and ultimately affirming journey into the grim future we all face. Once You Know confronts our global trajectory of ecological and civilizational collapse and doesn't flinch or reach for false hope, but helps find a way to live with a truth we cannot unsee."
— Roy Scranton, Author of Total Mobilization: World War II and American Literature
"Cappellin doesn't mean to overcome all of the consequences of climate change. He, like many experts, concedes that it may very well be too late to stave off economic disaster and a collapse of global exchanges due to energy depletion. Instead, his film focuses on our collective ability to confront the challenges ahead and adapt by turning to one another for support...It is a powerful narrative that takes us on a journey around the globe."
"An inspiring documentary, with a stimulating subject, with magnificent images...A deep and powerful reflection on collapse"
— Profession Spectacle
"Exposes the vertiginous gigantism of the consumer society and its inexorable decline. In response, the director tries to identify the new narratives that emerge and that attempt to explain the challenges facing humanity...Tells the story of the author's intellectual development, from the moment when he realizes the fragility of our society and the possibility that we have passed points of no return, suggesting the possibility of global collapse."
— Mr Mondialisation
"A film that encourages awareness...In this committed documentary film, the director sets out to meet 5 major climate and energy specialists to understand how to live and think about the future in the face of energy depletion and climatic runaway...The film is a great entry point that lays the foundations for a complex reflection on the energy transition and the urgent realities of the planetary situation."
"An excellent way to accompany your own inner journey"
— Jacques Tiberi, EscapetheCity
"Inspired by an apocalyptic sea crossing on a container ship, he sought out climate experts to learn how to stay hopeful in a world on the brink and best bring about change to try to save this rock we call home."
— NZ Herald
"Intimately portrays four international figures in the fight against climate change...Another documentary with a bittersweet flavor. Sweet for very careful photography and extraordinary landscapes; and sour for the conviction it conveys: that much will be lost in the coming decades if we do not react in time, as individuals and as a society."
— El Pais
— Resilience Journal
"Cappellin does not lose sight of the wider context; instead of creating another warning of the impending crisis, he shows how to minimize its effects. He visits people who have had to learn to deal with extreme weather events and their aftermath and talks to experts who are looking for practical solutions for difficult times. Sooner or later we will all have to face the tough questions posed by his film."
— Konrad Wirkowski, Watch Docs IFF
"This intimate yet undeniably ambitious documentary serves as a wake-up call to a planet on the brink of climate-induced collapse...Cappellin's film boldly tackles the big questions confronting everyone today, as population growth and diminishing resources further the trajectory towards the collapse of everyday life as we know it....this poetic and haunting documentary deftly balances global fears with our own personal uncertainty and hints at a future where individual and collective resilience can offer some hope in the acceptance of unavoidable and fundamental change. An important film that's guaranteed to stay with you long after you've witnessed it."
— Adam Mattera, Raindance
